Exactly! All AL diff setups are $$$$$. that is why I just saved that money and bought the UE 1/8's instead of screwing around with the stock diffs. UE 1/8's cost the same amount of money as buying AL housings, diff cups, and RRP gears and I've had the 1/8 diffs since they were first released and no ring/peione wearing or breakage just a once a year spider gear rebuilding costing $20 total.

hmmm.... clicking on aceleration. icould be the tranny mabey diffs still depending on how hard you are on the breaks. I had a dual disk setup on mine which gave incredible rear wheels up stoping power but it was also hell on the poor diffs. if you don't get it figured out bring it on the 21st and run it because I know several of us will know if its the diffs or tranny just by the sound.
