I've been chasing down a vibration that has be plaguing my car for a while now. I swear it didn't come in until after I changed my rear end out. Well, one area that has concerned me is the axles have almost no hub for the wheel adapters and thus wheels to center on. I'm afraid I don't have my rear wheels centered and that's causing the vibrations. Currently, the adapters are centered by me tightening each lug down evenly and attemp to center the wheels.
Here's what I have for a centering hub. 1/8th total protrution but only 1/16th is flat. The rest is the chamfer.
Think this is enough for me to get new adapters made that have less of a chamfer on them and fit tight enough to what's there to be centered? I really don't want to get new wheels. That's not in the budget now.
I've had the wheels balanced on a road force machine. Pinion angles are -2 on the transmission and +1 on the rear end. Going higher on the rear didn't change anything. Having the rear lower didn't either. Vibration comes in right about 60 to 65 mph and doesn't change with RPM only speed, and it doesn't change much as I go faster either. Only thing else I can think to check is the driveshaft.
Suggestions beyond the topic at hand?
Thanks
