Re: Still vibrating but better
Open driveshaft. I am going to have the DS rebuilt. Angles are right so is the balance but it looks like the ujs are not aligned.

Re: Still vibrating but better
You never posted how the rear axle is installed, what supports it?

Re: Still vibrating but better
I remember when I put a 67 4 speed in my 59 corvette I had to raise the tail shaft about 1/2 to stop a vibration. JMHO.

Re: Still vibrating but better
I'd like to revive this thread. I know this is better suited for the Hamb, but there's a lot of talented people here on the barn that deal with this problem. When I installed the new motor in my car, I had to raise the motor mounts up to clear the oil pan which was modified for main bearing cap supports. That pushed my angle to 3*. I'm not sure what the original degree was, but I don't remember any driveline vibration. Now I need to correct my rear angle by 2.5*. I purchased the proper shims and installed them yesterday. My original reading at the pinion yoke face was .4*. My 35 coupe has a Ford 9" with parallel leafs from Weedetr. After I installed the shims, I put everything back together and dropped the car back down on the wheels. I climbed under to get a reading, and I was getting 5* of angle on the pinion yoke instead of 2.5.
Can someone tell me what I may have done wrong? Thanks |

Re: Still vibrating but better
Was the flywheel and clutch balanced?
