Im in the process of rebuilding my rear end. Ive never done this before but I am very competent when it comes to just about anything mechanical. Im taking it slow so I dont mess anything up in the tear down process. My pinion bearing went out and caused it to try to climb the ring gear and busted a tooth on the ring gear. Chewed up the exciter ring and some of the shims are broken. Any tips that could make my life a little easier during this rebuild? Anything, any tricks I should know? Thanks for any help.

 

This thread came at a good time! What was your torque sequence on your side adjusters? Manual calls for 75 ft/lbs, but read other 4x4 site, and some stated up to 150 -200ft/lbs .http://www.ringpinion.com/TechnicalH....aspx?TipID=11 . The weird thing.... was when I loosened the side adjuster to pull the carrier out, I simply backed the adjusters out with a flick of a screw drive from the small access hole.

 

Is yours a trac-lok? Are you doing the rebuild with the diff in the truck?

Hmm, how about you ask me the questions and I will do my best to help you out?

I needed a big mother 3/4 inch drive johnson bar to tighten the pinion nut to the required preload.

The used rear diff i purchased for rebuild was very very grungy inside I used oven cleaner, a toilet brush taped to a wooden broom handle for inside the axle tubes and a nice strong pressure washer. LOL

Please shoot me a pm or ask in this thread?? I do have more pics too.

 

My manual said 75. I torqued each adjuster to about 10 ft lbs with the required backlash. I then tightened the right side to 75 ft lbs and checked backlash. It was close, however when I went to tighten the left side adjuster it was much too loose and I had to start all over again I played with the left and right adjusters until I had the right backlash while maintaining a 75 ft lb torque on each adjuster. Hope this is clearer than mud for ya. Let me know. I can copy and paste from the manual I have.

 

pm's.. why pms? keep that stuff out in the open!

good job by the way.

 

When making adjustments on the side adjusters for the backlash, make sure the whole ring and pinion is turned over several times forward and several times in reverse.
I read that that centers the whole assembly after adjustments have been made and seats the bearings correctly. Thus aiding in setting the backlash.

Thanks, I already have the PDF manual.

I applied that process as well.

I had a minor setback, my homemade tool for the adjusters broke. I have to wait til my neighbor gets home to re-weld it with a new grade 8 bolt. I'm hoping i can get some good gear patterns later today.

 

Good luck Nbrion1 ! Im working at getting this diff installed in the truck today. Man, I wish I could have sourced backing plates!! I have the 3.92 diff out. A little cleaning and quick paint while Im at it. .. Hope for test drive tomorrow!

 

Haha! Sweet, I'm pulling for ya! I'll be doing this same this evening. Got my fingers crossed!

 

I found a very good write up on setting gears on a jeep forum a little while ago, definitely worth a read if you're going to attempt the job yourself.
