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. |

Update: I filled the diff with Lucas regular 80w90. I did mostly highway driving with a couple of parking lot maneuvers. I notice a little noise in tight turns but nothing bad. On the way home I made a hard right turn from a stop and got on the gas hard. The LSD locked up hard and sideways I went. The same LSD with the expensive grape flavored synthetic gear oil, I would have lit up the right tire.
I'll drive it more tomorrow, but so far the diff actually seems pretty happy with no friction modifier. Much happier than the synthetic stuff. |
