i have had a weird vibration the last coulpe weeks in the rear end i thought it was the tire because my right rear last week slipped a belt and looked like a mountin range when i was done but that didn't fix it i checked the u joint and it doesn't seem to be anything wrong with it .it only seems to do it on restarts when i get on it hard and coming off the corners. was wondering if maybe running that tire might have messed up the ring or pinion?also would a bad shock cause anything like this it feals like the left rear is hoping and i had a push tonite that was not there before i asked my guys to watch it and they said they never seen it bouncing tho. i guess i should add this i'm runing a stock 7.5 with welded gears and a t-350 tranny

it sounds like a tire spinning wheel hop thing. i'd check both rear shocks before i went any further. if they're soft, try stiffer ones.

i did have alot of hop in it last week but the track was super hard and slick and last nite it still had some good grip in it. i do have a set of good shocks to put on it i'll just have to run 5th lol i got a different drive shaft today gonna try that also

here's another suggestion if your rules will allow it. lower the rear mount of your lower control arm about 1". it'll help plant the tires and give you better forward bite.
