Yes, good advice. The thing I was worrying about was that it would be necessary to back off the threaded carrier bearing adjusters (doesn't use shims) to get the original carrier out of the diff housing. And that it would then be a pain in the neck (requires special tool inserted through axle housing tube) to get everything back to the original lash after installing the truetrac.

Here's the deal...There are 2 adjustments (3 if you include the bearing pre-load)to setting up a rear end, pinion depth, and backlash. Pinion depth is already set up, and shouldn't need to be adjusted if you use the same gears over, and by checking the amount of backlash BEFORE tearing it down, you can thread the adjusters all you want to get the carrier out & back in.
After re-installing the new carrier, adjust the threaded collars to achieve the correct bearing pre-load, and original backlash, with original backlash, the pattern should be good to go...

Progress? Let's Git 'R Done !!

I was just talking with a good mechanic today. He pulled up the service manual on the Titan on his computer and we were discussing the Truetrac install. He said no big deal. He already has the tool for the carrier bearing adjusters, which he welded up himself. He drove my truck in 2WD on an icy sidestreet and he thinks the ABLS with the wheel spin - brake clamp - throttle cut is, to use his technical terminology, a PITA. Without me saying a word about the subject, he pointed out the cross shaft pin of the OEM carrier as being a weak design feature.

She goes in at 8;30 am.............

do the burn out mod and see if both tires spin. since it won't be under warranty anyway.... I think it would look nice since all Titan's thus far are one tire spinners. Man, I sure wonder what they'll say about needing custom tools to align the gears... This sounds like it is going to get expensive, real quick lol. I'll see if some of the guys here (gear shops) have the tool and have installed trutrac's before I get mine done.

rear end is in, now they just need to put it on. they're mechanics were busy yesterday and today... I'll call the GM as he said they'd work on it same day parts arrived.

To be more clear on what I said earlier, the GM said he ordered parts and it'll be fixed in two weeks, for which I made my second appointment for the same crap they could've fixed a month ago lol. The day of the appointment, I had to go in to sign papers to order the part, it was actually not ordered the two weeks before. Even though it was allready three weeks since it broke. this is week six or seven. Call the GM again tomorrow to fire someone lol, AFTER they fix my truck.

Now I too am worried about the price of the TruTrac getting installed lol. It wasn't in yet when I called the 4x4 shop last week, I'll call again when my truck is fixed. later,

I would think that somebody who was experienced with rear axle work in a well equipped shop should be able to take care of it in about 3 hours since you don't have to mess with the pinon. I saw a shop labor rate chart that had 5 to 6 hours for changing everything in a rear axle housing and setting up the gears. If I have this done, I would try to order the Truetrac with new carrier bearings already pressed into place and with a new set of races.

O4DRUNNER · 11-16-2005, 07:41 PM

so far no good news

due to someone at the mfg, the side gears in the tru-trac were not made correct,,,,, the splines were not finished correct so the axle only goes in about 1/16 of an inch.

so after phone calls they are pulling there remaining stock and checking them out we should here from them thursday,,,,,,,

so no posi burn outs yet,,,, i hope this is a fast fix,,,, and trac tech steps up with help to the shop on the labor,,,,,,,

pics are in the photo gallery

Sorry to hear about that. I hope they take care of this quickly. Thanks for blazing the trail.

so... what you're saying is no news may be good news on my trutrac not being in... that sucks, I sure hope it isn't a wide spread problem with these now! seems more guys are having rears replaced due to ring and pinion than shattered spiders, most get the howl and whine and replaced rear... so I may not solve the problem getting a LSD... sucks

I'm wondering why they always replace the whole rear axle? Cheaper for Dana that way? Or some misalignment problem with the housing itself?

The service manager quoted me $27xx as his cost on an axle assembly. I'm glad they replace the entire unit - there are probably quite a few dealership techs with the skills to do gears, but there are at least as many without.
