Chris, I have not found a manual....
What about the link (to the manual) I posted in reply #5 of this thread, and you thanked me for it in post #9?....
Read the manual, and read it again, then when you think you have it, read it again. It's an important set of steps that need to be followed TO THE LETTER.... As I said, set the backlash and preloads wrong and it's 'goodnight drive'..... (and by the sound of what you're doing, the workshop is helping you buy a new drive from them!)
Let me say this. I have done dozens of those drives, and I never once did one without using the special set up tools for the job. Even with that many done, I still wouldn't just 'do it by feel', which is what you have done. The depth of the drive gear with the bearing pack is set by the shims you put in. Those shims control how far in the drive gear sits. It needs to be accurate to within a thousandth of an inch.I don't care who you are, nobody has eyes that accurate, hence the special tools. You also replaced the upper drive shaft top bearing. That bearing is also shimmed to set the bearing pre-load for the upper drive shaft. Too tight and the bearings overheat and fail, too loose and the shaft is prone to 'rattling around' and the gear teeth will fail. Did you set the preload with a roller torque indicator? Did you then check the driven gear height? Also requiring to be set to within a thou. When you have the driven gear height and upper drive shaft preload set the housing is ready for the drive gear, but that also needs to have the perload set and the gear depth shimmed correctly. Would you rebuild a motor vehicle differential without all the right tools?
Chris.......
