How doI engage the CDL on a 2001 disco 2 ?

 

That's a bit histeric isn't it? As I understand it, the failure is caused by the cateletic converter heating the grease inside the u joints, causing it to breakdown over time. If they replaced his old drive shaft with a new rover driveshaft, it's going to take some miles before the cats heat the grease inside the U joints enough to cause them to fail, right?

That said, I agree he should have greaseable u joints, just that he shouldn't fear driving till he can get it done if he has a brand new shaft.

 

Jon,
I sent you a PM.

 

Ok replaced the front prop shaft within two days it failed. Did not break transmission I had it towed home. Ordered new shaft with zerts in u joints and on shaft. Drove 60 miles begain feeling vibration again. I removed front shaft , manually engaged cdl. No vibration. This is in a 2001 d2. My question is. Why is it destroying new shafts? What am I missing? I am totally lost on this one.

 

Ist off you should really start a new thread - take a look how old this one is.

Next your problem is not the drive shaft at this point it has to be one of three things

• Front diff
• Transfer case output shaft - most likely to my mind
• Broken mounts

Functionally the problem is your drive shaft is not sitting true causing binding and failure, most likely excessive side to side, vertical or combined movement.

You need to make sure that the is no movement in the output of the transfer case or front diff, give the speed of failure I am betting the output on the transfer case moves a lot or the mounts are completely gone
