Not the kind that make my 2 year old little girl giggle, but clunking from the diff of my stock 10 bolt.
I noticed it after my track day last week. I'll try to get a video of it tonight. If I have the engine off and let the car roll backwards down my driveway, I hear clunking. Probably not supposed to do that, huh? I did get some nasty axle hop a couple of times, I know that's hard on it. If it's bad, I have a stock axle off my 99 parts car. I just need to swap the brake lines and brakes over. I believe that's the only difference. |

Really? Everything I read said torsion is better for road racing. Well either way, I've got a free one, so might as well use it.
I'll take the cover off my diff tonight and see what parts fall out. I need to learn how to work on a diff anyway, may as well be now. I do need a write up or something though. |

QUOTE (Steve91T @ Mar 18 2016, 12:50 PM)  Really? Everything I read said torsion is better for road racing. The older, high bias Torsen T2Rs are better for road racing than most clutch pack/cone type diffs, but not the low bias, stock, Torsen T2s. The problem is that Torsen stopped making the Rs for our 10 bolts a while ago, and even the latter ones they did make had bad case cracking problems, IF you could even find any of those.
