thanks for all the heads up. it is in my 84 ute. i have a serious shudder above 80km/h and i origanlly thought it was the wheels till i popped it out of gear to listen and the shudder became worse and when i went to select 4th again it wouldnt go in. i was thinking of getting a LSD in the rear axle i have to getting it looked at but they will charge me the same as it would cost for a R31 diff from Mad Dat. :(
