YJ Pinion Seal Tips

Ok guys so I am going to replace my pinion seal this weekend sometime and was wondering if anyone had done this? I figured while I was at it I would do a yoke swap and convert from those flimsy straps to u-bolts. Anyone have any tips/suggestions for doing this?
Thanks

Pretty simple and very straight forward honestly. Don't let the end caps pop off the u-joints.

I have no experience at all with the JKs and I assume that is what you are going to do this change to. Correct me if in error.

I would get some 1 ton U joints from a junk yard and regular U bolts and then redo it. That way you have much heavier U bolts and those snap clips go away.

I have 1 ton DLs with CV joints front and rear in VEX, the 1983 CJ-7, and its great.

Just a thought.

Ok so from what I have gathered I can mark the nut with a paint marker and the yoke and count the turns that it takes to take off the nut then when putting it back on i count the turns and line the mark up. might be hard since in doing a new yoke and new nut. anyone know the specs on the tork for this nut?

Robert this is being done on a YJ. I think I am on the YJ forum. (correct me if I am wrong) and I specified it was a YJ in my title. thanks for the help tho

IF you don't get an answer by the time I get home from work (graveyard worker) I'll check my Chiltons manual for specs.

Basically put a pipe wrench on the yolk and a breaker bar on the nut and tighten it till you feel no play back and forth on the pinion it's a simple install when you don't have to crush a brand new crush collar I had the specs from all data but they wer wrong they wanted it too tight so I did jus like I posted. Same gos for all pinion nuts

The Marking the the nut trick only works with the same part. If you are putting in a new part that isn't the exact same thickness it won't work.

Anything with a bearing in it, like a Wheel hub you need to do as suggested above and get to where it spins with no play. Some people tighten it to just where it stops spinning and bring back to where it starts spinning again.

This will minimize wear from being to loose or too tight.

The number given by Chilton is 210 ft-lbs for 87-90 for the Pinion nut. For 91 to 94 they give as 6 in-lbs over the release torque that want you to measure before you remove the nut and after it is installed. The release torque is how much torque is required to rotate the pinion using a torque wrench.

Thank you guys this helps a lot. I have also heard about the play thing on the yoke. This sounds pretty straight forward.
