SteveRK Posted March 3, 2008 Share Posted March 3, 2008 At that speed i would guess that its not wear in a UJ. I recently replaced the U/J in the rear prop at the axle end (it has massive ammounts of wear) and never had any clunks - What i did have was vibration at around 50-60. If you are getting a definate 'clunk' check out gearbox mounts as well as U/Js Quote Link to comment Share on other sites More sharing options...
