Ray, your vibration still sounds like tires. Not every one balances them quite right. Most balancers have a round off mode. Close enough for most, but not all. You could also have a tire slightly out of round.
The newest balancers have a road force load compensation as well. These do a fantastic job. Any Chevrolet dealer should now have or will have the latest balancer.

Ken,
Would you suggest that I try a GM Dealer vs a tire dealer?.. I haven't had them balanced yet. Also will get alignment done, but was going to a local tire dealer for both. If you think a GM cert is a better choice that is good with me...

Lifetime MemberThanks, guys. Y'all were right about the motor and tranny mounts. The right motor mount and the tranny mount were both shot. It was already off the rack by the time I got to it but the mech. said the drive shaft moved over a little. Hopefully enough to get tunnel insulation in. At least it shifts into first easily now. Also, what would be a reasonable labor cost on replacing all six u-joints?

Lifetime Member 78 bucks an hour! YIKES!
I'm in the wrong business. I only charge $38 hr. 
The local mech. that put my mounts in said he'd never done it before, (the half shafts) but didn't think it would be too much of a problem. He said probably around $125-$150. Sounds like a good price. Does this take any special skills if you have manuals? Not for me, for him.

The "end play" Chips is referring to is the play in the side yokes on the diff.(where the half-shafts attatch). Check the in/out movement of each of them. A small amount is OK, but I think the accepted measurement is around .010-.015".
It's hard(if not impossible) to get the half-shafts out with the car on a lift, or otherwise "in the air", unless it's on a drive-on lift. With the tires/suspension hanging, there will be pressure on the shafts. You may need to take the shafts off with the car on the ground, unless your mech. has a drive-on lift. You can raise the car, and take all of the attatching hardware off, and then lower it to the ground. The shafts will almost fall out on their own this way!
