Detroit TrueTrac Installation -- Difficulty Level?

I was talking to my mechanic buddy about switching out my differentials (currently D30 and D44 both open diffs) for Detroit TrueTracs front and rear...I know some folks are wondering, why LSD units instead of lockers and the answer is simple...I do a LOT of snow driving in the winter living outside of town and working just outside of city limits on the other side of town.

My buddy has never done much in-depth gear work...he just took over the auto shop his grandpa has owned for over 30 years so when they need to do gear work, he just pays his grandpa to do it for him since he has a lot more experience. When we got to talking about installing the Detroit TrueTrac unit, he was asking if it was just one of those where you basically pull out the old stuff and pop in the new or something like that...I can't remember what all he asked, it was kinda over my head. Or is this something where you gotta pull the old stuff out and then do a bunch of shimming and adjusting to perfect it?

I guess what I'm asking is... does the installation of a Detroit TrueTrac (gear driven limited slip differential) involve a very complicated installation with a lot of very specific adjustments or is this something a decent auto mechanic can basically unbolt the old stuff and bolt in the new?

The reason I ask...his grandpa said it'd probably cost around $300 per unit to install (maybe less...can't remember), whereas if my buddy does it...I can work out a trade deal with him and save a considerable amount of money.

YES. Ring and pinion will need reset.

Thanks, I think that's exactly what he was wondering... I'm assuming that when the ring and pinion are reset, that's where the shimming and such comes into play?

Just as a side note (and this is not my forum), I have an Eaton Detroit True Trac in the rear of my Jeep YJ with a Ford 8.8 conversion - and I love it!

The True Trac is a monster on the trail and a "pussy cat" driving down the Hwy and running around town.

Yep, that's what I've heard from everyone... it works great when you need more traction but it won't cause understeer and fishtailing problems when driving in snow. Basically the best of both worlds. And since it's my DD and will not see any tough trails anytime soon (til it's paid off and I have a second DD), I really won't benefit from lockers anyway unless I wanted to shell out some serious bucks for air lockers.

I didn't wanna start a new thread so I figured I'd just bump this one up... I've decided to start saving for Detroit TrueTracs so I can get em installed before winter. Quadratec has em for the Dana 30 for around $400 and the rear Dana 44 for around $520. Anybody have a better source...preferably cheaper...?

4wd.com has the D44 for $461.99 and the D30 for $394.99

They're always running deals on free shipping as well. AND they'll price-match anything they sell.

Damn...I totally forgot about 4wd.com and that's who I do 99% of my shopping through too! D'oh!

Thanks for the reminder...lol

So far I'm up to about $400...so I'm looking at around $900 for the diffs and I was quoted $300 per axle for the install, but since it's a buddy's grandpa doing it...I'm gonna try and either work out a "quantity discount" or see if I can work something out with my buddy as far as a trade deal goes (design their shop's website for half the labor off or something). Wishful thinking probably...but worth a shot!

So did you ever get your truetracs? I'm thinking about getting one for my front axle to supplement my factory LSD in the D35 rear. (If I regear in the future, that is. I'll do both at the same time.)

ARB is a little more complicated. gotta be careful with air line routing. R&P setup & master install kit still required, just like any full case carrier.
