the half shaft uj has massive play so i did as according to haynes manual and took the diff cover off to release the shaft, on inspection i didnt need to as my diff doesnt have a clip holding the shaft in as the book states! anyway my question is i noticed there was some play when turning the half shaft(the bit that wasnt worn!) the play seemed to come from the carrier and smaller cogs is this normal? should i be worried? the crown an pinion gear seemed solid 1998 tj 4.0 normal open front diff
