I just had a Speedmaster installed. The rear end shop couldn’t set the end play. Specs call for .006 to .008 in. I have about a 1/4″ on each side. Today I received a reply from Speedmaster regarding how to get the axles to seat properly. The response was ” Tell your shop they “need to do a 1-piece axle conversion”.
Well, that requires replacing the tapered axles with straight axles that have the hub as part of the assembly. This would also require new seals and axle bearings. They had no information on what axles, bearings, seals, etc. would work.
