Hopefully that fixes it. Driveline vibrations and other difficult to diagnose problems can be frustrating as hell. I've had a good run so far with all my vehicles and not had any vibrations.
My tire shop couldn't even balance my Weld wheels because they didn't have the proper 5 lug attachment to clamp them down for balancing, they didn't understand how these wheels should be balanced, they were spinning them up and telling me they're bent as **** and to send them back, but I read the Weld Racing instructions and I knew the tire place don't know wtf is going on.. So I just took them and ran them on the car as is and without any balancing my car still feels 100% winding the speedometer right over.
If you repair your T56 and still have the vibration, all it could be left is something wrong with your pinion yoke, maybe it's been machined off center.. you never know these days. Personally I'd only run either a genuine Spicer, or a Strange or MW chromoly pinion yoke.
