Might want to add that disclaimer to the first post just in case. Definitely easy, but for a complete newb, not including those details could be disastrous haha

I called Detroit and they said to fill with factory spec oil for the axles, but they also told me the TT diff likes regular plain 80w-90 gear oil. The lps had the Royal Purple on sale. Two new bearing, red loctite, and RTV.

I'll post pictures of the progress step by step, it's very easy.

Now that's a recipe to cook up some burnt rubbers.

E-locker is a 4wd feature. And you would never want to replace it with TT. TrueTrac is a limited slip diff. E-locker creates a positraction style setup ensuring that both wheels spin at the exact same rate. If you're doing any sort of offroad as your signature semi suggests, then E-locker is much better. Of course, unless those big tires are just for show.

As I was reading this thread I had the same thought as AcidJake75 on the backlash and preload settings. I've read that this information is necessary but I have no clue as to how to go about it or what tools to use to achieve the desired results. I would be quite interested in reading a detailed description of how this process is performed.

The limit of my experience with rear ends has been to remove the diff cover, check my True-trac for loose bolts and change the lubricant.

Thanks for the writeup as on the True-Trac installation as it is quite educational.

^^^has to be done - or it may fail early...Those who have had to replace their entire rear end know what that costs. For those that just want to "eyeball" it... Be my guest, its your $$..

You need a dial indicator and some gear marker

The gear marker will show the contact pattern on the ring gear.

AcidJake75 · 11-21-2012, 08:27 AM

Here is an ok vid of showing you how to do it..You can get a dial indicator from harbor frieght for cheap ($15 bucks)

how to check backlash on used gears for 12 bolt posi - YouTube

This will ensure proper function of your differential. I cant tell you how many I have done on a 350z including my own (Carbonetic 2way diff).. I cant wait until I do my install on the T. This thread is still good reference of whats all involved..

Had my ring and pinion gears changed out about a month ago and figured I should check it out,so I drained my gear oil and pulled diff cover. Man I am I lucky or what? I am thinking or What. well this will be FOUR times I have had to tear this rear end apart, all trutrac bolts backing out again. I am mad. Mad at the tech that did my gears for not checking to see if they were lose and Mad at my self for not telling him to check and also mad at myself for not going to a tranny/gear shop to have the work done. OK I did the red loctite on the last go round that was at around 100,000 miles I rebuilt the trutrac myself and gave it to the shop to install It lasted over 30 thousand miles but I guess the new ring and pinion gears was to much for the loctite to hold ( the vibration from install and break in) But Don't Get Mad GET EVEN! so Thanks to this thread I am going to do it myself great job spoolie for the write up and thanks to Acidjake75 for the final bit of info on the Backlash and wear patterns. That video in AJ's last post is great it will also lead to others that are quite useful. anyway with TT to back me up this should be a easy job and when it's done I will know it is DONE RIGHT! Thanks again to spoolie for getting this repair out ( so the carpenters on the forum can do this job) and to Acidjake75 for the fine point's.

this should be a sticky I could not find it in the how-to section and it really should be there. ( did I miss it ) Oh yea I am going to do the loctit again but this time I will let it cure more before I put the gear oil back in at least 24 hours.

BlueBOB · 12-07-2012, 06:55 AM

Ouch! Sucks to hear amigo. Glad you caught it before the fecal matter really hit the oscillating device... Good luck with the rebuild

TA CC TX · 12-07-2012, 07:01 AM

^^^ thanks I have done enough other work on this truck and others so I figure it's time I did it myself and Learn something Too! just need a dial gauge and a slide hammer!

**spoolie** · 12-07-2012, 07:50 AM

It's very very easy...the backlash is a quick check.
