Man. Nicely done. There is a handful of people who care enough to put the time in to explain the intricacies of jeeps systems. For real, well done bro
Thanks!
Top shelf info that needed to be explained! Looks like it's best to get a QD2 system on a GC. Glad I saw you video and thanks for producing and sharing your video! Great job too!
This clear explanation of the distinction between Quadra-Drive II and Quadra-Trac II is very effectively illustrated with the video footage of the systems in action. Anyone going offroad in muddy conditions will do well to watch this lesson and thereby avoid getting stuck.
This was SO helpful for me understanding all that stuff! I’ve got a 2013 Trailhawk with the Quadra Trac 2 system and I have noticed a couple situations where staying on the gas and letting the Jeep work out the terrain itself worked out! Now I know why so thanks for this video! The comparisons with you talking about it made it very easy to understand
Your a legend. Ive been watching you for a while now. I must say i have learned tons of info on my Wk2 now.
Thank you and keep up the excellent job.
Love all the way from Oman 🇴🇲
Another very informative video. The differences between the two systems is crystal clear now! Thanks yet again, Brad. See you in about a week.
Absolutely! Looking forward to it!
Hi, I have a QUADRA DRIVE II on my 2007 JEEP Commander CRD...and I love it!.
Thank you for your illustrative video!
I'm new to all of this. Very informative here man. I just got my mom's mint condition 2017 Overland with 11k miles. She passed from cancer and loved the vehicle. I love it too!
Very pedantic and interesting functional comparison of these systems. I didn't know anything about the difference when I bought my QD-II JEEP GC. I just know it handles like a dream on rough terrain. I got lucky! Thanks for the education.
This was a really good video!! Actually was really fun to actually can watch working the both systems!
Glad you enjoyed it
Thanks a lot, I've been looking stuff and specially videos that describe how wk2 act off-road and all what I was finding were musical videos with wk2 passing by obstacles that my tiguan do everyday, or at the best I was finding videos of pure footage with no description and technical knowledge behind... so useless videos for the pleasure of the eye only. This video is the best I've seen and so far I feel that I knew some very very clear and useful information ! Thanks for your scientific spirit.
Sure thing! Glad it was helpful!
One of your BEST videos. Love to show it to friends of mine who think our GC can't go some places
Glad you enjoyed it!
Very good explanations of the various Jeep drive systems, Brad. Until I started following your channel I didn’t know a Quadra Trac, from a Quadra Drive, from a Flintstone mobile. Now I “Yabba dabba do!” ☺👍❤
Bro, great explanation! Thank you 👊🏻
Thank you, great video.
I have a wk1 diesel with QT2, I live in Canada and the winters get rough, but with my little tank, never had an issues getting out of difficult terrains.
Thanks for watching! Have fun out there!
I have been driving Grand Cherokees for 28 years, two for 10 years each, plus the present one is now 8 years old and find your videos very informative. Many thanks.
durable strong suvs!!
Your vidoes are VERY helpful in going into the details of Jeep drive and suspension for the WK2. Jeep should consider you as a spokesperson, IMHO. I'm currently searching for a WK2, and as n3rd eng1neer geek I really want to dig into the details as to which rig I pick . You have helped my decision. Thank you!
Thank you for detailed explanation the difference of 4WD Jeep's sytems.
I have understood it, finally:))
60 seconds into the video and already crazy thankful for it. Very curious about how to tell which I might have and how they behave side by side.
I have a WK1 with QuadraDrive2. It feels unstoppable. Even in sand. It has Vari-lock in the front and the rear
Excellent explanation, I have been waiting for this Thanks !!
I’m glad it was helpful!
great video with really good information. I am about to order a new GC and have been on the fence about which system to order. This helped make my mind up. I was leaning towards the QD2 but wasn't sure of the difference. Thank you for the great comparison.
Awesome! Glad it was helpful!
Very well explained, great comparison
Great demonstration Brad on open differentials! 4Runner for ever thought. Lockers, rear and middle dif locks are essential for your type of of terrain. I hate electronic assistant features that nowadays are common on most real offroaders0 having the right tires with the right pressure and most importantly a competent driver is a must. However, as seennin your video both Quadra trac 2 and Quadra drive 4wd systems are doing their job flawless.
This is great I’ve learned a ton from you.
Great video comparing these two systems. It's really a shame that Jeep has made it basically impossible to get the quadra-drive II on a Grand Cherokee now. It seems like they never actually produced any in 22' with the Off-Road Group due to parts shortages, and in 23' now you can't get the off-road group on anything but the 4xe Grand Cherokee.
Ausie videos of wk2 had same clicking. I think they indicated it was the transfer case chain jumping and slipping. QD2 has limited slip rear differential using clutch plates, not a true locker. Looking at the diff cover, if you see cooling fins, then it has QD2 ELSD. QT2 has a smooth diff cover. I’ve had both and it’s definitely better with QD2 in more extreme terrain.
Another great video thanks mate
Thanks for the video!
Nature's challenges, conquered! Offroading enthusiasts, dive into the heart of this thrilling video.
Great! Useful video!
Brilliantly done!
Brilliant !
Thank you for info!
I was wondering if there was footage of my Jeep slipping backwards up that hill every time I gave it gas. You warned me to watch out for trees at the top and then I promptly ran into one about 30 seconds later. Lol. Such a great time. Enjoy all that delicious pizza!!
Always a blast to head out to the trails with you!
Tks Man! I have a 99 Grand with Quadra Trac II and I just bought a 04 Grand with Quadra Trac II with only 93k miles on it today. I'm very excited about it but I want to say thank you for the explanation, now I understand more and feel more Learned! Tks man! I'm in Eugene Oregon BTW . We have lots of mountains but very little legal trails if you know what I mean.
My 99 WJ 4.0 is quads Trac 1 system and on dirt climbing hills it's great, haven't tried it in mud yet but won't spin a tire up dirt hills regardless how steep. I like mine
Very informative. I am picking up a new Summit with the Quadra Drive 2 and the Quadra Lift Suspension. I was very curious on the difference between the Quadra Drive 2 and Quadra Trac 2. Now I know I bought the right one. What I really like is how the suspension automatically adjusts depending on which terrain selection the driver chooses - select the terrain and the Summit does the rest. As dummy proof as you can get. Thx!
So quadra-drive 2 over quadra-track 2... Got it! Thanks for the video and showing how it works, always wondered about that but no one really explained that well
Happy to help!
I have the 05 Quadra drive 2 trail rated Hemi and I can go everywhere I want and I do not spin tires. Great video. Great explanation.
@ZenoSwarm Sucks! Cool.
Those are mean machines. I just bought one a week ago and love it !!! Tires also plays a big roll in traction...
This was a great video on the workings of both systems. I have an 08 GC Overland, Quadra drive 2, I’m fairly new to all this and the only problems I’ve had so far has been due to operator error, just not knowing what I’m doing yet. My friends all have wranglers, rubicons, and sports so they are a bit different than me lol. Thanks for the videos.
Glad you enjoyed it!
Your 08 grand cherokke actually has a better QD2 system than the new ones... your has the ability to fully lock all 4 wheels (basically like a rubicon)... unfortunately jeep stopped using that system in 2011...
GREAT video!
Excellent explanation!
Great demonstration, I would love to also see a comparison of the QT1 vs the QT2, I realize the difference is QT2 has 4x4 low and the QT1 does not but I would really like to actually SEE the real world difference it makes in the WK2.
I second this. Would love a break down with the QT1 in the mix.
Thanks for making me look at my 'new' used GC Trail Hawk window sticker and realize I have the Quadra-DRIVE II
I had a 2017 GC limited 4X4 on the 18in wheels and then I had a 2019 Summit 4X4 on the factory 20in Pirellis and the way I can describe it is that I felt the Summit with the Quadra Drive and Air Suspension made going through some scenarios extremely easy…. While having TRD Tacomas getting a bit stuck 😂
Thanks for this video. I'm having trouble figuring out with Grand Cherokee will be good for me. I don't plan on going to moab or any of trail as tough as you guys are going. I just need to be able to get through the snow and to camp grounds that RVs would get too. I think I can get the lower trim 4x4 and I'll be ok.
yep, just get a 4x4 and you'll be fine
Pro tip learned 1/2 to 3/4 of the way through this trip. If you have quadratrac II give it a little gas before letting the break go and it will help you crawl out.... at least with the ecodiesel. Awesome video Brad!
Thanks for this. Good tip!
Great explanation..dear thanx
Great info - thanks!
Glad it was helpful!
I have a 1999 wj with 4.7 and Quadra drive in it we just got our first snow and ice so far so good
Superb videos! I have a 2019 Altitude 4x4 so I believe it's got the Quadra Trac I. Would love if you had a video with some QT I offroading. Could be a fun challenge! :)
I am also curious about some quadra track 1 analysis. You do a great job explaining things and this system doesn’t get a lot of coverage. I understand it’s basic and basically open, but I’d be curious what your input/experience was with this system. I just got a 2011 WK2 26x (the loaded v6) and it has quadra trac 1 and I’m curious if it’s even worth putting armor and sliders on.
Thank you for the great information. Still learning about my WK2. I know it has QT2. I aspire more to back roads and modest exploring, so I should be fine. I appreciate the information on knowing the differences between versions.
Yep. You will be good to go!
I had to trade in my WK because I need a truck. The truck is great but the WK has been my all time favorite vehicle.
Solid information.
Great video! I had a 2005 GC with the hemi and QDII, and it was an absolute snowmobile thru a foot and a half of snow. Have a 2019 GC Limited with QTII I bought off lease (and a 2016 before it). They did have some hesitation on snow and mud, compared to the QDII. I hear you about the instant response difference. What tires were these Jeeps running? I had Michelin oems on the QTII and was disappointed. Falken ats on the 2005, and now Pirelli Scorps AT Plus on the newer one. Curious as to your experience with different tires...
Great video!
Thanks!
Learned a bit from this video I've been a ford guy and I've been thinking of making the switch to jeep.
I would agreed 100%. If I knew and I had one with drive 2 I would more likely keep it.
Awesome Video, I bought a brand new JGC Limited 2021 4x4 with 5.7L and it has teh Quadra-Drive II.
I was in Texas Hill country a few months ago with 500 miles on my jeep and had to climb a loose rock/gravel road up a mountain, it was easy and would have been better with real tires vs Factory :)
Quadrack ll,
The spinning axles engage the servos in the axles that lock the differentials. There is also a servo in the transfer case that lock the clutches in the transfer case either in 4 high or 4 low.
4 high is full time 4wd and open diffs front and rear in high range spinning locks the diffs and t case.
Great video, I just wanted to know how and who installs those front rails on the jeep. I need one
Question? Does the Quadra Trac 2 or Drive 2 system(s) comes with a "control" panel on the dash console for 4x4 off-roading in the Jeeps that were in the video? I have a 2016 Grand Cherokee Laredo with NO console for off-roading but I have a "sport" mode and I do believe I have a Quadra-Trac 1 4x4 system. Is this true? Great video!
Great info in the vid! I have a jeep commander with a 4.7 and qd2. See any Jeep Commanders out there?
Great video, very informative! But how do I identify QD2? I’m specifically looking at 2014 Overland models. Is there an easy way to Identify?
I actually have a 1995 jeep grand cherokee limited ovis 4.0iL the the frist gen quadra-trac awd and its my trail rig and daily driver its a beast off road
This is really good. Should be posted on Jeep's website. Spot ON! I would never have the guts to take my WK2 / Quadratrac II through this terrain, but it is good to know that it could do it. Is Quadradrive II a true locking rear differential, or a limited slip differential? Brake lock differential really helps. For on road use, Quadratrac I or II is all you need.
Hello. According to what I read on 2005 QD2 5.7 limited, the QD2 with front and rear limited slip can send up to 100% power to the one wheel with traction and lock the front and rear anywhere in between and all the way up to 100% full lock.
In the past that clicking sound was concluded by some to be the transfer case slipping, not sure if these still use a traditional transfer case with a chain like the older jeeps. Definitely interesting
100% true ive definitely experienced a slipping transfer case in my Jeep SRT aswell as GM light duty pickups occurs often when u have the front axle in a high load scenario coupled with larger tires the Jeep transfer case seems to be very heavy duty and can take a beating. Just be sure to change the fluid more often as that is an extremely important item to keep in mind
Nice vid! You've probably have figured it out by now that the popping was from the transfer case and that it should be inspected.
Just got my 2021 GC Trail Hawk!👍👍😎🇺🇸 I need to change my logo to red. I have been that guy with an open diff. Never again. Good illustration. Popping sound? Been to an Autocross lately? lol, hero mode, Sort Traction Control engaged. Its the Anti locks being engaged.Great review!
Congratulations on the new ride!
The WK ( WH in some markets ) Jeep Grand Cherokee Quadra drive 2 has front and rear electrically operated limited slip diffs and a center diff in the transfer case and low ratio so all the engine power can be directed to 1 wheel if necessary .
Great video.
Thanks!
Thanks for a great video. From my experience with the QTII, no need for extra throttle ever. Extra throttle will lead you to lose control over your vehicle. If you started climbing at the right speed, and the BLD, QTII, kicks in, stay exactly on the same throttle. It would take between 1.5 to 4 seconds to pull you out of the situation, with less harm to the Jeep and more control to the driver.
you probably dont care at all but does any of you know a way to log back into an instagram account..?
I stupidly forgot my account password. I appreciate any tips you can give me.
@Koda Harlan Instablaster =)
@Magnus Jaxtyn I really appreciate your reply. I got to the site on google and I'm waiting for the hacking stuff atm.
Looks like it's gonna take quite some time so I will reply here later when my account password hopefully is recovered.
@Magnus Jaxtyn It worked and I actually got access to my account again. Im so happy!
Thanks so much, you really help me out !
@Koda Harlan You are welcome :)
Jeep had both systems available with the air suspension early in production, you could even get a V8 in a Laredo trim back in 2011-13. So you could of had air suspension and QTII or QDII theoretically. The one way to tell is the rear diff. If you have QTII you have a 195mm differential ,if you have QDII you have a 230mm differential. All are made by the German company ZF. Both systems are good and utilize the same transfer case, with only difference being that QDII has the ELSD. QDII is better but smart driving and learning how to use the Select Terrain system is key. QTII will get you there it might just take some better driving and more patience. I'm on my second WK2 with QTII. I opted for that because I did NOT want the air suspension. I lifted my Jeep(Dobinsons Suspension) and for what I do it's perfect. I've done trails that my buddies have done in their PRO4X X-Terra & Tacoma TRD Pro. The WK2's capability drastically was improved with the new 8 speed ZF transmission. With a 44:1 crawl ratio on V6 models you can really get into some gnarly stuff. Choose a good line and lock into 4LO and these vehicle will surprise most people.
I contract for ZF and I support this message!!!
I have quaddadrive 2 in my 07 jeep hemmij
How can you tell if a gc has qd2? I know it came on 4 trims but when I’m looking at listings it’s never in the specs, I see qt 2 sometimes.
According to my build sheet, I have QT2, QD2, and rear ELSD on my 12 Overland Summit 5.7 4x4.
@@urbangroomer They'll tell you. No, wait that's how you can tell if someone drives stick.
I am glad I've hung onto my 2012 GC Overland as newer models no longer have the front e-LSD. So far I have mainly used it in beach/sand driving and mostly get away with selecting Sand/Mud in Selectatrac but for serious deep sand, the QD2 does a great job in low range with the fully locked diffs/transfer case making it almost unstoppable. This video shows that QT2 looks like a poor cousin and while it gets the job done, it needs a bit of finesse on the the throttle with a fair bit of drama whereas the QD2 makes it look easy. Shame on Jeep for dropping the e-LSD option.
I read that the new WL Grand Cherokee will have the eLSD on both the front and rear axles when equipped with the QDII system.
Would love to see a comparo of the WK1 & WK2 QuadraDrive II systems. The WK1 system uses an electronic limited slip (up to full lock) on the front as well as the rear.
yo tambien tengo wk1-06 qd2 y bloquea mejor que ese trailhawk. vaya qd2 mas rara, que le ocurre?
@ posible qd2 questa mas?
@ Desde 2011 el sistema Quadradrive2 solo tiene diferencial ELSD trasero, al diferencia del tuyo que tiene ELSD adelante y atrás.
Great info thanks , I was leaning towards a used WK1 as I didn’t want air suspension, although in my research I realised the Q-drive was a better system. I’m still on the fence . The WK is looking a better option for suspension upgrades …
Mine qd2 commander doesn't have cooling fi s on the diff . Wonder why?
The ELSD in the Quadradrive system operates like a fast-acting soft locker. It locks very quickly at very low speeds, unlike many other lsd's that only lock when you have both wheels turning before one starts to slip. Quadradrive ELSD is virtually instant engagement of the LSD.
Yes. I have found this to be the case.
I have the only WJ 4.0 Quadra Trac 1 system I'm aware of in my area. Hard to find videos on them 4wheeling
From what I can tell, if you have a low range button, you have the QD II system, the base model has the Selet-Trac, if you have a Neutral button its a Quadra-Drive I. Some models have the system written on the center console. Get the Quadra-Drive II if you can. The QD II is standard on Limited models of the older WK 2005-2010.
My 2008 WK Limited 4.7 has QT2, 4Low and Neutral. Maybe the Limited 5.7 has QD2 standard🤔
@@omaralexanderarmuelles2259 Yes because i have a 2005 limited and it does have the QD2
@@omaralexanderarmuelles2259 I have a t handle lever for 4 low next to shifter
@@datcrazywhiteboy6205 5.7 Hemi right?
If I am not mistaken all jeeps (wk2) come with traction control TC, this feature breaks the slipping tire to allow the opposite tire to spin (because open diff) sometimes this is not enough and you need more power and TC will keep braking your tires, you need to turn off TC and accelerate while breaking (mildly) this way you force both tires to spin at the same times. I mostly use my hand break at half to force the two rear tires to spin at the same time.
The clicking noises is when you enable 4lo and the TC gets disabled by the computer, then there is way to prevent slipping, but if you have QDII the ELSD gets activated and disabled To transfer power from one tire to other, that noise is normal.
QT - capability to have AWD by adding a differential in the Transfer case
QTII - AWD with LSD in the transfer case
QD - LSD front and rear
QDII - ELSD front and rear
QL - Air suspension
TC - only works on 4Hi or AWDm and uses the ABS computer to achieve power transfer.
(LSD-limited slip differential)
(ELSD- electric LSD)
QD Quadrant drive, QT quadratrack, QL quadralift
QDII clutches are controlled by a computer and cannot act as lockers, QD acts by centrifugal force, me in you have to accelerate for the clutch to engage.
If I am mistaken please feel free to correct me.
Bought a 06 Grand Cherokee 5.7/QD2. I don't do off roading but we get a lot of snow. It doesn't disappoint even though it has shitty tires.
Great video！
Thanks!
Hello. The story I’m telling myself is that to keep the throttle on so the system can work as it’s supposed to, learning to use the left foot to apply brake pressure at same time as needed to modulate speed is just as important. When I’m trying to get over a tough obstacle, my instinct is to give it more throttle to try and power through instead of applying steady throttle to let the Quadra drive 2 do its thing. Then I end up using too much throttle and it is not a graceful entry or exit.
Then one time in band camp….. I hit the accelerator instead of the brake and that almost turned into a disaster.
The Quadradrive 2 worked best in the earlier WK models with the ELSD front differential. Moving away from ELSD in the newer years made them far less capable..
I love my 06 WK with Hemi and QD2. I've put an OME lift on it and BFG KM3's and can go anywhere
Thank you for your comment! You mention "OME lift". Does that include an OME full suspension overhaul or is that purely a "lift". I don't know much about suspension or OME so if my question doesn't make sense or seems unnecessary that is why. Thank you.
Other then watching the wheels is there a visual indication in the vehicle to know what system you have? Or is it possible to find out using a search of its vin # ?
I've got the Quadra trac 2 in my 2012 durango crew. I only handle light to medium mud here in the south. Have you tried the difference in obstacles in low? Some sights say that it locks the front and rear shafts but I'm not sure how true that is.
Hi there. Really well made video showing the differences in 4x4 systems.
I got a question: My used bought jeep did tend to drive to the right side. Today I did an alignment and the front left wheel wasn't aligned.
So, you drive really bad roads up and down. Did you encounter any alignment issues?
I feel like we may have a slight alignment issue, It's on a list of things to get checked out when we are able to. But considering what we have done to the thing. I think it's doing great.
I have a '23 JGC Laredo w/ the QuadraTrac 1 (QT1) system. You can borrow it to shoot a comparison video if you like. QT1 vs QT2.
I think that sound is your rear locker engaging. My 01 with Quadra drive and vari lockers makes the same sound. I definitely don't have active braking...
Every WK I've owned states what drive system is fitted on the centre console. 😎
Where's the love for the wk qd2 with front and rear lockers ? It's a shame they stopped putting the front locker in when they went to the wk2.
It is. And we need wk owners to come out with us. In order to show that love. 😁
@@ProdigalOverland I'm in MI with a WK QD2
@@JordanKaczmarczyk we will be that way in May
Totally agree. My WK2 QDII is a better, more comfortable all around vehicle in every way than my old WK QD2... but the WK was absolutely the better off road machine. It crawled tank-like over most obstacles.
Hello. My 2005 with 5.7 and QD2 with 2.5 inch lift, is a heavy beast. With proper throttle control it goes just about everywhere except when it won’t. Usually the weight or lack of clearance is my issue, and my poor throttle control. I’m working on two pedal throttle control to become better. An awesome spotter is even more important that can see the proper line when I cannot.
Hi 👋 I've only recently learned about Quadra Trac 2 vs Quadra Drive 2 so finding this video was enlightening. Ive read that Overland and Summit trims had Quadra Drive 2 but i gotta assume the Trailhawk has to have it as well. Is the correct?
Yep all Trailhawks are Quadra drive 2
I have a 2014 wk2 diesel. Getting ready to lift. Im not sure even what the drive train is but it has the knob in the center with mud, snow, sand? And 4 low. I think its front wheel drive but uses allwheel drive when it needs to. It have cenrer diff and front and rear lockers.
I'm looking for a good used GC. 2011- 2015?? Which models or trims have the Quadra drive 2 with the ELSD? Do you have to get air lift to get the qd2?
Why didn't Jeep ever tell me this. I never knew about the active braking in 4wd and now I know how to use it properly Thank you Thank You
Both systems can direct more torque to the front or rear axles.
Quadra Trac 2 uses brakes to get more torque to a specific wheel.
Quadra Drive 2 uses an electronic slip differential to get more torque to a specific wheel.
Yep, But only the rear has the ELSD in Quadra Drive 2
@@ProdigalOverland so on the QD2 the front uses the brakes like the QT2
@@johnviera3884 yes. In the current version (wk2) you only have a rear elsd. The front is the same. Open brake lock differential as the qt2 system. If you watch out latest video you can see it’s limitations
Bought a Trailhawk because it has the QD2. Handles well on the beach in the deep sand as well.
It sure does!
@ZenoSwarm Sucks! not every overland has the qd2. But it is an option.
Quadradrive II is awesome. I’ve got it on my WK Hemi. I’ve had a lot of modified rigs and the Quadradrive II has been the best I’ve experienced.
I am going tomorrow to buy a 2006 WK with Hemi and Quadra Drive II system. It says Quadra-Drive II near the low range handle, so it was easy to see what drive it had. I think it is a good deal at 7400 bucks.
Great video! I wish there was at least a VLSD available for the QT-II system.
Yes for sure!
Just Purchased a new Jeep Grand Cherokee L Summit that has QD2 & ELSD. Im a little confused with this video...
