When I bought my car, it had bad rear springs. I addressed that soon after I bought it. It rides, drives incredibly smooth and quite as far as vibrations, etc. With exception I get a very small vibration in the tail shaft when I hit 65 mph or hammer down at slower speeds on occasion. Without a doubt, it’s coming from the driveshaft. Because I can see that it tickled the drive shaft tunnel. The motor mounts are brand new and tranny mount seems pretty descent. The U-Joints are brand new and the vibration was there before I replaced them.
I realize the driveshaft could use balanced or bent, yoke could be issue or tail bushing.
Regardless, I know the pinion angle is off a half inch or so in angle at front of drive shaft and the rear is pretty darn close to being perfectly straight. This is with weight on the wheels. I think it’s off enough when the car squats a tad in the rear under acceleration, it’s causing vibration. I need advice on how to straighten pinion angle at front. Can I slightly raise front of engine to drop tranny at the tail ? Is there a way to drop the tail housing by other means ? Drop the tranny crossmember ? Unless, the driveshaft is bent or out of balance. Or yoke is bent. I’m sure the pinion angle needs addressed. Because, visually looking at it in the front. And there is zero slop or movement in the driveshaft or yoke when I grab it. That eliminates the bushing too I believe. That and it doesn’t leak. Any advice or know how to address front pinion angle based on my information would be appreciated.
