- Your Centre Diff.
The heart of your Land Rover's constant 4WD system is the centre diff. And it is a part of your vehicle that's not always fully understood, or worse, not correctly used, leading to almost guaranteed failure and costly repairs!
Brad from KLR clearly explains the clever inner workings of this crucial part and shows us how to use it correctly to extend its working life.
Great explanation-the text description in the email was excellent and the video brought it to light. Thankyou
Great explanation. I once drove my Defender 110 300tdi about 80kms at highway speeds on bitumen with the centre diff accidentally on lock (i'd just finished working on it with it jacked up and LR recommend you lock the diff while doing this). I'm pretty amazed nothing exploded, although I've been worried about it ever since (some 50,000 kms later...)
Great Video Brad, you are a gem to the Perentie community. Bloody nice.
I have friends who firmly believe that the difflock should never be used until you get stuck. That way you have something to get you out and home again. Which is silly, of course. As you said, the first thing you should do whenever you hit loose surface is engage the difflock on a full time FWD or the FWD on a part-time system (jeeps, etc). It makes the vehicle much, much safer and easier to drive.
My landcruiser used to wander side to side on icy roads 'til I tried the dif lock, always used it after that.
Brilliant explanation Brad.
How about a part 2 on when there is an ATB centre. When do you then engage your CDL?
Also keen to get some more info on this as I find myself not needing the CDL as much with an ATB centre.
Sound advice and a well put together video. Keep up the good work.
Absolutely ❤well explained and something I do all the time.
Awesome explanation! Thanks 👍
Excellent explination of how and when the centre diff lock is and can be used, I myself drove from the South of France back to the UK with the centre lock engaged towing our camper trailer due to the front propshaft breaking
I have always believed the Part Time 4WD set-up to be superior .
Engage Hubs when you hit the dirt and Engage/Disengage the Permanently Locked Centre on the fly with no issues .
Good explanatory Video for people with limited/no mechanical knowledge .
Here in the UK most people never use the diff lock or low range so things seize up ,((especially in the early Discoveries that had a diff lock )
Ironic considering Range Rover was the first to do it all!
Brilliant video mate!
Great explanation. It's like scratching a chalkboard to me when drivers "brag" they didn't need the diff lock when crossing the Simpson or going thru Wonnangatta etc.. Early Rangie owners made a lot of Warranty claims over this "premature wear".
Hi Brad. Awesome video. Great to see you on YT!
Great minds think alike, I did a video on this exact topic very recently.
Great explanation!
Well explained. Dave Ashcroft says that this is the most common point of fail in the LT230 etc. Why LR deleted the CDL in D2s is a mystery... well, they were experimenting with traction control.
Plus, engaging the CDL on gravel makes the car far more stable.
I wonder now about my subarus that have awd but no diff lock.
Only watched this 'cause of my Subaru's - they have a set of clutch plates that auto locks the diff when slippage occurs, like a limited slip kind of deal. Amazing bit of kit. I've got a couple in bits - when they failed I stripped them to show the mechanics who were arguing the toss about how they work.
thanks.. love the explanation, I have always stopped to tuen it on and off, can you turn off the cdl whilst on the move also? I normally have to reverse a bit to get the light to turn off.
That sounds more like Automatic Free-wheeling Hubs rather than a CDL .
@@johncunningham4820 Both my Rangeys and cruisers needed to be backed up to get the dif lock to let go. Really annoying when you're trying to get out of a tight spot onto fast roads.
Awesome - great visual explanation! Way too nervous though to lock while moving in my '95 Defender tdi.
Question: with a tricky axle twister, I really hate the idea of sending it through, because of how fast the opposite wheels get spinning before biting again. Would stomping on the brakes while full on the throttle simulate traction?
Not stomping on the brakes but trailing your foot on them w/o the difflock is very effective. It was taught to us in the military driving humvee's as 'trailing brake modulation". Basically, it's just keeps a little brake tension on the discs to keep them from spinning wildly if/when they break traction and not destroy anything. Much easier done with an autobox, of course!
@@ailo4x4 very interesting - who woulda thought doing it without Centre Diff! Will definitely try that 👍🏻
