Detroit TrueTrac - Quality Issues?

Hey everyone!

I've been asking around on the TJ forum for 2nd opinions on how to repair my damaged rear D44, and have been thinking about adding a Detroit TrueTrac to replace the factory Trac-Lok. So far, several local diff/4x4 shops have been warning me against it. I was told manufacturing was outsourced a few years ago and the quality hasn't been the same since. One shop even went as far as telling me they just sent the 12-14 units they had back and were walking away from them entirely.

Can anyone confirm this? If so, are there any other gear-based limited slip options to consider? Not really wanting to spend the money on a Yukon or any other clutch pack based system, and and if I don't have many options I might just have a shop rebuild the Trac-Lok while replacing the ring and pinion so I can save a few pennies and put them towards something else in the future.

Just let me know what you think/know/have heard, and thanks in advance!

-Mike

I did a lot of research before I went with truetracks front D30 and rear D44. This is the first I have seen any mention of quality issues. I reside in the JK world but there are many on this site including myself that have not had any issues. I went to an ARB in the rear and will eventually move to a D44 and ARB upfront but that's due to the wheeling I have found myself in. They perform fantastic as long as you dont get a wheel in the air.

put 30k miles on my true trac's in my JK before selling it. the originals were limited on tire size the redesigned units that came out a few years ago were rated to 37" tires if i recall correctly.

Thanks guys! I found a shop that will do the ring/pinion and TrueTrac for the cost of what everyone else is charging for ring/pinion and Trac-Lok rebuild. Prolly will give it a shot!

That sounds like a good plan.
We put a TrueTrac in a couple years back, and my sister in-law went with TrueTracs front and rear a little bit after we did. Neither of us have had any issues, and both are very happy with the TrueTracs.
There is another player in the mechanical LSD market now, PowerTrax with their Pro Grip unit.

They are a little cheaper than the Eaton TrueTrac. I don't know how quality is, but a few have already went that way and I haven't heard anything bad yet.
