I have a 02 Eiger 4x4 5spd and I was playing around and put it in reverse with 26" Vamps and Spun the back tires over, so i found out how easy it was so i hit the gas harder and i spun them a long ways and right before i stoped spinning the Axle hopped and jerked and i could hear the tranny knocking! Before I done that I have alot of times made the Axle hope by Going up ditches and hitting the gas and also pulling people out of mud bogs, want this hurt the Clutch? I think I have already messed something up!

 

if ur axle moves back and forth probably bearings gone or seal kit... then again like me i needed awhile new carrier... take it apart and inspect to prevent further damage....
