Hey everyone,

I recently purchased a 3.9 ring and pinion set and am planning to install them soon. My question is what parts should I replace while I am in there or is everything good to go. My friend will be helping with the install who is much more knowledgeable then me but I figured I'd ask before we hit any speed pumps. I appreciate it.

 

If you are going to take it apart, you should be replacing all of the bearings, seals and should replace the caps with hardened parts. You will also need a crush-sleeve or a solid sleeve and shims.

Do you have the proper tools to read the turning torque adjustment to make it properly? If not, you must get or make one.

 

where can one get the crush-sleeve/solid and hardened caps?
