I drove the hour up to Mark for a transfer case for my 07 Tahoe (Autotrak)after the original rubbed through, and I came across your original tcase video. Mark is an awesome guy and a stand up business man, called him up and he had one ready next day. This was about 3 years ago I believe and its been great so far. 😎👍
Hell ya.
Thank you so much for this video! Today I discovered a small oil puddle and it was below the transfer case, I was worried it was pump rub. Thankfully it wasn’t because it didn’t have a hole where it could leak. Turns out it was an output seal needing replaced. I’m going to put a pump rub kit on my transfer case as well as the seal. You saved me a ton of time and money. You’re the best!
Mark you are a transfer case legend guru the dad of all T-Cases the amount of knowledge you have/share is amazing the automotive world needs more people like yourself,I’ve learned that you don’t like to send someone down the road with JUNK you’d rather give the best of the best and see the work speak for itself you deserve a standing ovation I wish some of the builders around here could go 1 day to marks T-Case school 😂😂😂 but another great video and lots of knowledge job well done sir.
When I rebuilt my T-case 5 years ago, I bought the pump rub kit. Super glad I did.
Here’s my lottery dream take my 05 Duramax diesel to Mark and sit and watch him rebuild my transmission and when he is done with that have him do the same for my 04 1500 Sierra. Mark at Kodiak is a legend. Truly admire a craftsman who knows his craft down! I know I’m not the only guy who has watched mark rebuild a transmission more than once…😊
My 2006 Chevy 2500 4x4 Duramax got 713000 miles 26000 hours and the same transfer case not a rub hole yet. But I change the oil in the case every 15000 miles using Lucas oil additive. Had to replace rear axle at 475000 miles but haven’t touch the transfer case. Guess I’ll keep changing my T case oil every 15000 miles. Live in northeast and always towing and using 4x4 during winter use. Again maintenance is been my key to not have break downs.
That's awesome! So you use 5w-30w and some Lucas oil additive full synthetic?
I watched a video years ago and started using Mobile 1 5w-30w full synthetic 2 qts. Good thing I did it replaced 3/4 qt of ATF that drained out 😅 Thanks Brother 🤠
@@ronaldbabbitt6318if you have an np246 with the auto 4x4 then congrats you fucked your transfer case by not using the proper recommended ATF
pump rub has absolutely nothing to do with how often you change the fluid and if you have an np246 with auto 4x4 you need a autotrac compatible ATF or you’ll completely fuck the clutches.
@tylerj6327 My Duramax HD2500 is not an suv or Suburban with the np246.
If interested check Rockland Gear or Kodiak DIESEL I did my research.🏁
@@tylerj6327 look a Keyboard warrior giving advise🤣🤣🤣. I’m now at 865000 miles still waiting for the clutches to F*** up like you say. Your Clueless and should be quiet because your info is clearly false or I would have had failure by now.
Without videos like these I wouldn't know of his products. Spreading the word up in Canada.
Have had my Kodiak transfer case for 2yrs love it!! It did give me better mileage as well.
Great to hear!
i did mine at 45,000 miles with the merchant automotive kit. the best kit available.
320k miles on my 10/05 build date 2006 LBZ w/261XHD... Gets run in 4wd almost every time I drive it as my sub has a steep hill that tends to washboard and 4wd helps keep it smooth. So far no pump rub hole in the case but when it does get one, I'm planning to put an aluminum rear case half on it... That roller bearing chain drive gear looks nice too!! Jeep took out the bearing when they went away from CAD, because everything is spinning all the time but with CAD, our trucks run that gear metal to metal, with only lube film to keep it from wearing... A bearing there just makes sense to me... FWIW, I run half and half synthetic ATF and synthetic 80W90. Thickens up the lube some but not as much as 5W30, since atf is ~10wt and 90wt on the same scale is like 30wt engine oil IIRC... The steel friction doesn't care about the 90wt but if you try this in the BW case with non-steel frictions, it will dissolve them and then grind going into 4wd... ask me how I know... :(
Videos like this is why I follow your channel. Thanks
I appreciate that!
So, I looked back at the pictures of the worn parts from back when I rebuilt my T-case. My old mode shift fork has the chain rub Mark was talking about. 😖
I think I'll be ordering a reman unit from Kodiak Truck when this one falls again.
This was a great video. Super informative
I designed those cases. GM wanted magnesium. We tried to talk them out of it with no success. My uncle Warner was the chief product engineer when they designed the NP205 and other older NVG models.
Awesome information, thank you sir!
Plus, I’ll make sure so I can follow. I want to learn more. I just bought Tahoe the 71 2003. I’m replacing the other one, but I still want to buy a better one and replace it.
Great Price for a Great Transfer case! Excellent work 👏 Thanks 🤠
I put in one of kodiak trucks cases and been awesome ever since installed.
Hey Josh could you do a video on parasitic draw or grouding issues (LOCATIONS as well) for LMM and LBZ and how to test for them. Appreciate it.
If you see this and end up doing it, include the LB7 too pls. Wiring is a b*** lmao
I've been replacing my u joints after realizing what the noise was on my truck had no needle bearings left and loose as a goose at first I thought the input shaft on diffarental was loose lucky I only needed u joints
Aluminum front case halves are available now? Thats great, the aluminum rears are markedly better in every way I can see, even the structural ribs on the outside are thicker than the OEM.
I really wouldnt go to anyone else but Kodiak if I was looking for a full replacement unit at this point. That rollerized carrier bearing alone is worth it, but the full aluminum unit being offered now makes it a no brainer. The only thing I dont agree on, that I did different was the merchant auto pump-rub plate, filing down the lugs is necessary to allow it to shift around freely like the OEM assembly to prevent binding when using the Al rear case half, but I feel getting rid of those knife like lugs on the OEM pump assy altogether is the best move. With such thin pieces of metal, even if you arent wearing the new Al case I feel those stand the chance of wearing down over time.
Of course I recommend adding something like the merchant auto or PPE t-case brace regardless of what route youre going. Peace of mind is priceless.
Hey TM I absolutely live the sound of that turbo on your red truck but anyway I have a 08 gmc sierra duramax dually that have a MP1626XHD Transfer case RPO code NQF are there any weaknesses in this tcase it currently has 304k miles and has been trouble free for 15 years and counting
Beautiful work but I am horrified at the parts and complication of todays transfer cases. I own an '86 f 250 which had one of the earlier aluminum / chain transfer cases and after rebuilding it and seeing the light duty nonsense I gave it away and replaced it with a new process 205. I love my np 205. I also replaced the lighter duty T-19 transmission with the np 435 transmission, much nicer and heavier design. Hard to beat big gears, tapered roller bearings and gear oil. I realize this isn't for everyone.
If vibration occurs, then no . Radial thrust tolerance should be minimal, might have wear in case on seating face.that amount gear lash is normal
Used that original video to rebuild my case back in the day. The mode fork wore out but I didn’t know it was the rear snap ring groove. Rebuilt it with a case saver and went on my way. For about 3k miles, then it did it again. Got an aluminum rear half and rebuilt it again. No issues this time. Swapped to 0w-20 motor oil as the viscosity is very close to that of Dexron VI. I change it once a year and it always comes out the same way it went in. I also fill through the speed sensor port so that it’s very full of oil.
Great info thanks for sharing
Good tip, I'm trying to remember isn't the typical recommendation to add an extra quart of fluid through the sensor bung?
@@blackbeardthepirate7467 i just fill until it comes out of the speed sensor hole.
@@brendan747 had to double check my notes, I put about an extra half quart in after a generous pre-oiling of the internals at overhaul. I've heard of guys adding an entire additional quart, but all the way up to the sensor bung sounds excessive and might cause issues. How many quarts did you add to get it there? Spec is 2 qts.
@@blackbeardthepirate7467 it’s is over 3qts. i don’t remember precisely how much. just till it comes back out the speed sensor hole. has been like for 3 years/60k miles with no issues. plenty of time spent in 4hi and low
I gonna have to look at my chevy transfer case thanks for the information truck Master
Any time!
Great video thank you. Awnserd all my questions.
Damn... I had a bad feeling in the back of my head when I did my pump rub upgrade kit, I kept thinking, what about the snap ring and bearing holding it in... They are probably worn as well.... Really wish I would of done more maintenance as well while I had it open., I also JB welded the pin hole, but it's been over a year now still good 🤞
536,000 miles on 2015 RAM 2500 4x4 Cummins Diesel I went to 5-40w Diesel Synthetic oil not the ATF4, and my Transfer case has lasted without problems, every 33k change the oils in 2Diff, Transfer Case and G56.... Diesel oil change 5k, (oil clear not black) and fuel filters every 5-10k depending on "environment" and 100k =coolant, brake, steering.
Don’t think Ram spec’d atf+4 for the transfer case for a few years on the 2500+ t’cases. They used it back in the older ones, pre- 2010 or something like that. It’s a b&w fluid on the newer ones(my ‘14 & ‘17 are anyway), similar appearance to atf, but not the same.
Im getting my 04 silverado transfer case right now should have seen this before taking it to the shop
my transfer case just started clunking really bad at 340k (pretty sure its those snap rings or the chain is slapping around) Getting a Kodiak transfer case next week! :)
Been there a little brake clean and some QUIKSTEEL and I definetly did the right thing and fixed it 😂😂
I have to agree on the best unit out there. I wish I would have seen it video before I rebuilt my t case I think ur t case is at least a 400 k unit I have the factory 273. I'm not unhappy with it. I've done lots with my truck and the tcase is not in bad shape. I replaced all bearings chain and sprockets cost about 300. I bought the parts from Allstate gear they are decent parts. I am sure there are better. But when this t case fails at some point. I am a machinist by trade so I get it. And wish I would have but I think it'll last another 200 k or so I have a general fix for the pump rub without doing a bunch although I have no issue with the pump rub no failure on the dodge ram 04 I know it's silly puttied in place go figure not a fix for poor parts fitment. Also I u uses substantially better gear lube it reduces wear in many key points again nothing lasts forever. If I need another t case for any reason I will be calling you. Thank u
Just did the pump rub kit on my 2003 Chevy Avalanche.
Really appreciate your videos!
I designed those cases. GM wanted magnesium. We tried to talk them out of it with no success.
When you said 1,585 my heart sank. I just spent 980 for a used one without the pump rub kit 😢
Great info!
I have a 241 transfer case that hit all 4 gears on my 95 Yukon.
Replaced the phone based the 4L60E transmission with A 4L80E trans mission once installed this is the s 2nd transfer case! 😢 It will not shift! I'm watching your video and it looks like you know what you're talking about! HELP IM GOING CRAZY
I had a hole in my 06 2500HD. I put a MA pump kit in it with a new rear t-case cover. Went through all the drivetrain in the t-case. Bearings and other metal parts all looked good. The only parts I had to replace other than the new pump kit and case half was the thrust washer for the planetary, new pads for the shift forks and I put new seals all the way around. Been working fine for several years now.
My case saver made it 5 years before the same thing happened in my 2001 2500HD
Is this for all years made? I have a 2015 LML.
Informative.
Tried using your code it doesn’t work with them though! Still great price and informative thank you!
You put the roller bearing on the shaft for a NP246? I was curious if that mod had been done for a NP246. Does the input bearing wear like that in the NP246 as well?
Im looking at doing my 263xhd , should i have axial (in and out) play at the output shaft of the Tcase?
My truck has a carrier bearing, so I guess I don't have to worry about the snap ring.
SOOOO this pump rub kit for the transfer case....is it just for alll or most diesel one's .......?? or for all transfer case's............?????? no matter how old they r or their currant mileage on ' em all.........................??????????
Truck master help buddy ……. when ur at a dead stop and let off brakes u can feel like the slip yoke move out of transfer case it feels like. Best way I can describe it , when u let off brake it feels like maybe someone tapped u in the rear .what would that be ? I have new tailhousing , new one piece driveshaft, slip yoke , ujoints , pinion seal all done same time. I have 6 inch lift . Truck had a clunk when put in drive or reverse so got the ujoints done and fixed all that while I was in there ! Thanks
I have an 08 crew cab dually 500k efi live on at 32k same trans, turbo, inj, everything. Just blew motor up 🤣 can’t complain thou, I just got new Motor and trans. but does T case on 08 have the pump rub issue. Thanks and thanks for the videos
.
Do you guys do 2018 Nissan Titan front differential rebuild?
Does this happen on the newer trucks? 17-19 l5p 20-24?
Yoooo truck master ily man
I would like to see another video on that Beast that you pulled out at the beginning of the video❤
Why are the manufacturers not made to recall these transfer cases and repair them this is wrong for the consumer as much as they cost all should be indestructible.
You want an indestructible truck?
@@Heywoodthepeckerwoodhahaha
recall is for safety issues not poor design . which is sad but that is all manufactures
I have question for anyone here. Is the drive train the same on a 07 2500hd duramax vrs 3500hd duramax? I'm thinking of converting mine to a 3500hd duramax. Besides the obvious rear-end, bed and gears match what else would I need or do?
Does anyone know the exact Loctite product he is speaking about at 19:08? I am petting for a rebuild on my transfer case and would like to use this.
What about the transfer case adapter that breaks
I’m ready to order the lifetime t-case. Can’t find it on the website.
I fid 2 of them. In a shop as s mechanic and do not knowvhow long they lasted
What if you don’t use the 4 we very often? Like your videos from central Florida!
WD
is this just a chevy problem ill have to look up my transfer case,I kind of stopped watching since im not really a duramax fan but still tune in for the info sometimes
So , Should I put 5/30 synthetic in my stock transfer case ? And if I never use four-wheel-drive am I in a better situation than somebody that does?
Unless you have a lever on the floor, all never using 4wd does is just about guarantee that when you want it, it won't work. None of the issues with this case are related to using 4wd so use it as much as you can. For the manual case, at least once a month just to keep oil slung around the front diff, with the electric shift t-case, shift that sucker in and out of 4wd at least once a week and it'll work forever. Leave it sit two years without pushing a button and you'll find that sooner or later it won't work at all...
I put the pump rub kit in mine about a little over a year ago it only had 67000 miles on it but even at that the little clip was broke into wasn't much wear but there was some I checked the bearings they seemed really good so I'm thinking it should last me years
Do you have to worry about this if you rarely ever use four wheel drive?
Yes you will still need to worry about it
No vibrate hole in the case broke the fork new case wish know about Marks case at that time
Does your coupon code still work? I’m planing on ordering one soon
5w30 synthetic motor oil in a trans case? That's a first. What's the deal with that?
Is this issue on HD only or is it including the 1/2 ton?
There is a list of transfer cases it affects, but yes 1500s are affected
Well buy one from hand's down. When well we hear about the new steel heads on the wifemax 😮
Mark
Has nothing to do with the video, but what bed cover do you have? Looking for a good one for my Lbz. Thanks
I think I bought it from rough country it’s a trifold
@@TruckMaster is it a tyger tri fold?
I'll be checking mine for sure. I'm getting ready to tow about #9000 1400 miles. I have 116k on my lbz. Should I be worried?
How did the trip go? I did 3,200 miles with about the same weight, and my LLY did great the truck has got around 170K
@@jessiedavis3543 NO problems at all. The 9.9 mpg kinda hurt but never lacked for power, having my cruise set at 77mph for long periods didn't help I'm sure. Cheers
Does he ship to Canada?
This was a problem 15yrs ago. Thought they were all fixed by now
That dude knows his $#!t.
I thought there was a point GM had updated rear case.
I know they did a different clip at one point but they still broke.
coupon code isn't working.....
Why do people setup their trucks for their wheels to stick out like that? Worse handling for what advantage?
Not being snarky, just trying to understand if most of the core goes into the trash, why is there a $700 core charge? What do they reuse to make it worth that?
I can’t speak for them but I’m sure there is a lot of good usable hard parts in the case that they can still use
Ok, yeah. I guess his comment threw me off.
so he is recommending using 5-30 engine oil even stock?
Yes 👍
I got a few questions. Anyway we can talk and answer a few questions for me
Transmission and transfer case redone don't agree with their work should been done right the first time
Send me one 🎉
so he ( ryan ) does the all alumn,. transfer case's all life time stuff........ is it only again for the diesel one's or can & will he do the say.....2002 G M C Sierra crew cab long bed 6 . 0 gas 4x4 that's manual on the floor ........... CAN HE DO BOTH THAT COME FACTORY IN THE GAS & DIESEL RIG'S.................???????? if so how much roughly for the 6 . 0 gas 4x4 on the floor t- cases say like in my rig here in...Ohio......... does he have any in stock for my sort of 4x4 rig........ or what...............????????
Be pretty easy to call Kodiak and find out
Toyota.
It's criminal that GM gets away with selling such garbage, prone to failure from the day it was designed on paper and they just never have to pay the price for it. The "Duramax" (Izuzu) engine is good, the Allison Transmission is great, the rear axles hardly ever have issues... the rest of the truck, absolute garbage, mostly made in Cheaper and that oem transfer case is a piece of junk.
If I buy one of these new manufactured Kodiac Transfer cases, can they bill GM for it?
2-3 mpg gain is pretty spectacular. Depending on condition of current transfer case, it will vary I’m sure.
Takeaway from this video, new transfer case from Kodiak will off set fuel economy lost by larger, more aggressive tires. Notes for review with my wife when she’s questions the decision.
All valid points 😂
does the kodiaktruck coupon stil work, would love to give them some money
How can I get this information either to buy a rebuilt or to get my own rebuild? Can you send me your address and phone number or email to contact? Thank you.
