CDL Engaged

[DiscoBell]

Just thought i would let everone know, i finally got my CDL linked so i can now activate while off road.

I went to watagans this weekend & did some fairly hectic trails & with the CDL engaged was very very impressed with the improved off road performance.

The traction control was hardly working only every now & then.

What a difference.

What are your experiences with CDL engaged??

Cheers for now

Good to hear.  I have also found that the CDL makes a huge difference.  It's great to be able to engage the CDL without getting out of the vehicle and crawling under it to try and fiddle with a hot transfer case...

Am I reading that CDL is 'controlled decent" ??

If so the Man at Landrover Land advised me when I was trying to work out the gizmoes on my V8 that it's not a good idea to use it to often as the ABS works it's ring off and gets quite hot. and at around $3,500 for a replacement"you be the Judge!!"

If I got the CDL wrong then disregard my concern guy's

No, CDL has nothing to do with ABS.  Glen should have actually said ABS AND TC (traction control), as they are an integrated system  ABS/TC is electro-mechanical, whereas CDL is purely mechanical.  In fact, with CDL engaged, the ABS/TC system works far less than without CDL engaged.  This is because the CDL distributes power with an even 50% front/rear split.  And as the ABS/TC is particularly sensitive to cross axle wheel speed differences, engaging CDL greatly reduces the power distribution differences between front and rear, thereby reducing ABS/TC actuation.

So the sum up is this: Basically use CDL when climbing or descending, and this will reduce the ABS/TC actuation to the point where you'll probably never notice it.  On the flip side, be sure to use HDC (Hill Descent Control) every few months by finding a really steep hill and engaging HDC, so that the ABS block doesn't freeze up.

Got all "Ballsed up" it was actually HILL DECENT that gives ABS a work out. Any way I'm all for a kicking if required. I will bend over but won't push back Regards Steve

Steve, looking back at your original post, and the fact that you meant HDC, I definitely agree with Glen.  HDC, especially with the V8, will tend to overheat the braking system, and has been known to cause brake fade on a long hill.  Using CDL will assist the vehicle significantly when descending.  I find that with CDL engaged in my TD5 auto, I rarely need to brake unless the hill is extremely steep and rocky.

Central Diff Lock?? think i'm getting it.

[Winaje]

Yep, CDL is Centre Diff Lock.    I just realised after looking back over the thread that CDL had not been defined.  It locks the centre diff to split the output from the transfer case 50% front and rear.  Particularly useful for towing large loads up slippery inclines (such as wet boat ramps  )
