[gmonde]

stick or automatic ? i just did the rear in my car,i bought the spool used,new 35 spline axles,yukon 489 case(good for 750 horse and the cast is a stronger blend) 4:56 richmond gear,new 1350 yoke,like jeff said the main caps have been suspect for breakage and pulling the threads,thats the reason i went for the new case,plus after doing some measuring on the maincap diameter,the carrier bearing was still a little loose even when torqued to spec,check your case gmonde
