Sure Grip unit feels much better than Eaton TruTrac did..

@72bluNblu what do you disagree with?

Dr Diff is invoking a PhD in his business name...which may be a "doctor" more along the lines of Dr Pepper or the Rug Doctor...but still, I doubt that he has a PhD in business ethics. Was I actually wrong about that?

He is evidentially strongly advising against a product...for which he's also willing to take your $500 in exchange for. :rolleyes:

It doesn't look good.

I don't know the man. I didn't even know it was one guy before this thread. My comments were mostly meant to be silly...but also made out of my own frustration since I just invested in one of these units on the basis of trusting the reputation of a product and trusting the word of a competing vendor who stands behind their work.

I do believe @jbc426 about his observations and it makes me wonder if I'll have to deal with this after pouring in a lot of time, money and work into the Dart this winter.

You’re 100% off base about Cass, aka, DrDiff. That’s what I disagree with. I’ve done business with him for years, bought everything from axles to disk brakes, even a brand new 3rd member with an Eaton Trutrac for my Duster that’s going in with my t56. I’ve called him, emailed him, bought products, you name it. He’s helped me out a few times diagnosing differential issues, even though there wasn’t any parts I bought from him involved. Even shipped me a couple parts overnight to get me back up and running. His knowledge and customer service is the best I’ve encountered in the Mopar world. So yeah, I disagree with you suggesting his ethics are suspect, that’s total BS.

As for the truetrac, I haven’t heard of any issues with them before this post, and I talked to a bunch of people. I’m pretty sure @autoxcuda and @GMachineDartGT both run them in their cars that are seeing plenty of track time. I’m not discounting jcb426’s assessment, and I’m not saying his truetrac wasn’t the source of his problem. But lots of people run them successfully. I’m definitely concerned about some of the issues he had because I haven’t installed mine yet, but there are plenty of parts in motion. I’d be interested to know if anyone else with green bearings has the issue, because I know the folks I talked to all run tapered bearings. Or maybe jcb426 just got a bad unit with excessive clearance. Or maybe it’s some combination of parts. Sucks with an expensive part like that, but it does happen, nothing is 100%.
