After taking down the differential assembly in the 42LE I am building for cleaning/inspection and new axle shaft support bushings I have found a severely bad problem. On both of the side gears (not the pinion gears) there are cracks on some of the gear teeth. For all I know they could have developed 5 minutes after the transmission was driven for the first time and be nothing or they could let loose the first time I put the unit back together and drive the car. Upon searching I am finding the differential guts are all more or less discontinued ? Since these share nothing in common with the 41TE on the final drive end.
There is a parts package p/n 5016367AA that comes back as NLA. The side gears p/n 4593110 also NLA and the pinion gears p/n 4593112. I think the side gears and pinion gears are listed backwards in the parts catalog. One hit on parts voice comes back for the 4593110.
Suggestions ? I am more or less really e'ffing screwed if I cannot find new parts here. I am not buying another transmission to maybe find the same problem. Would have thought at one time Quaife offered a differential for the Prowler crowd but I don't see anything besides a phantom grip when searching.
