2nd Gen Non-Engine/Transmission Carrier bearing & slip yoke failure

[abranz]

Hello everyone, just thought I would share my recent experience with my rear driveshaft. Truck was making horrible noise/vibration and I could smell burning rubber. I had a heavy load in the bed and was pulling 3 cord of wood in a trailer.

The slip yoke between the front and rear driveshaft failed to "slip" pushing the carrier bearing out of its housing and the front driveshaft into the t-case. Dissassembly revealed no lubrication and plenty of rust between the splines. This joint is normally covered by a boot and I suppose "lubed for life". I had our local driveshaft repairman replace the slip joint with one that is greaseable and now all is well. T-case appears fine. Just thought I would share this with everyone. Try to grease the splines by pulling the boot back if possible to help prevent the mess I was in.

Ouch! Thanks for the reminder. I had a similar problem with the front driveshaft, fortunately nothing else was damaged. I seperated the shafts, lubed it well and reassembled it. The splines were worn out a couple years later.



I have an old Volvo with aver 250k miles on it and have never had a problem. It has a grease zirk on it with a hole through the outer shaft to the splines. Now that my new front shaft is out of warrantee, I plan on adding the zirk.

A heavy load will make the drive shaft shorter, and you possibly have ran out of front to back slip. the rear drive shaft is up against the center piece.
