Eaton helical limited slip question
I'm thinking of buying an Eaton Detroit Trutrac helical limited slip. I don't offroad, but live on a gravel road and drive in some areas where true 2wd is nice to have. I currently have 2000 2wd 4.6L with a 3.55 ls rearend. The rearend shaking is bothering me. I put friction modifier in the rearend 20,000 miles ago and it did help the shaking but now its back. Also, at 70,000 miles I don't know how much longer my current limited slip clutches will last(personally I think they are fine at the time being but idk).
Anyway, the helical gear sounds nice since it's maintenance free and shouldn't ever shake. Any reviews on this helical limited slip? Is it a good buy? Does it truly not shake? Is it truly maintenance free? Thought I'd ask the off-road guys what they think about this rearend since you guys would be the experts on the best type to buy.
