 I replace the strut (what a chore!) then I checked the half shafts for loose universal joint(Larry (ie) corvette specialties)gave me advice on how to check.They were tight no movement.I pulled the rotor off and checked the parking brake no signs of rubbing there.While I had the rotor off I tried to move the flange to check wheel bearing no movement there.But I still have the squeak went I drive off (step on gas squeak let off gas no squeak).I am at wits end any ideas would be appreciated.I am trying to avoid putting it in the shop right now ,not a good time for that.
                            Thanks Rick

Have you put posi-track fluid in the rear end and driven in circles, first left, then right (or right, then left, your choice).  Find a big parking lot (read church or other with no light poles around) and when it is empty, spend a while driving in circles after you put the fluid in.

Use the GM factory (blue and white label on a black bottle) fluid at the back of most Auto Zones with the other fluids on the upper shelves (at least here in OK).

Are you sure the squeak is coming from the wheel?? sometimes sounds travels mysteriously from other places... might try checking the u-joints on the drive shaft... also, it could still be a u-joint on the half shaft, they might feel tight, but i've encountered bad u-joints that had no play in them untill i took off the half shaft(believe me, i just rebuilt a wheel bearing assembly thinking i had a bad wheel bearing when infact, i had dry u-joint bearings... ugh.. oh well, i needed the practice again setting up the bearings :) ), just from the pressure of having the wheel jacked up, the half shaft is being pulled outward toward the wheel from the differential, applying pressure on the u-joints and making it difficult to feel/see any looseness...

First I'm curious what dose posi track fluid and going in circles do?Hi Jim,You know I have the u-joints already so maybe I just change them anyway.I have to change the shocks anyway(I think the shocks are the originals white with blue GM letters).On my next day off I guess that what I will be doing,It cann't no worst than changing that bent Strut. Thanks Dennis and Jim.

Not sure of the chemistry behind it, but it worked for mine when I had the same issue, but usually when turning or going slow (meaning I probably couldn't hear it at speed or the car, much like a boat, comes up on plane and changes the axis of the rear end, wheel bearings, etc at speed).

Jim makes a great point in that I didn't know I had U-joint issues until I had the shafts out of the car.

Squeaks as you take off usually indicate dry u-joints...especially if it squeak-squeak-squeaks with the tire rpm. as in, it squeaks every time the tire/wheel passes a certain point.
Jimmy has a point...it may well be driveshaft u-joints, and just being "tight" doesn't preclude the joints being bad. They can have nothing but rust in them, and not have any play that you can feel.
If you check the u-joints on the halfshafts with the halfshafts off the car, they should turn easily, both the end caps, and the cross that is still in the shaft. "Tight" in this case isn't a good thing.
I'm going with bad u-joints... Or at least ONE bad one...

No place to put grease in Rich.I'm going to just replace them no telling how old they are.The good thing is I already have the u-joints for the half shafts /with fitting for grease.I'll pick up the ones for drive shaft this week.

I am taking them to work,got a press there.First I'm going to try the vise if that don't work the press is next.Joel said to watch out so not to bend the haft shaft flanges .I am going to take the car up to the base and put it on a lift for the drive shaft.They also have a press if I need it.I know my back will appecate thatLOL ,but seriously I hope this solves my problem.I only have 19 days till our road trip.

just a tidbit if you have't been there before, but the rear yoke caps on the drive shaft, i've found it much much easier to use a about a 2 foot+ extension on a ratchet to remove the bolts, coming from the transmission side over the crossmember..... otherwise, its 1/4 turn with a boxed end wrench if you take them off at the yoke itself(little clearance between the differential and the mount that runs under it to the crossmember... :)

 Got the vette back together today,and took it out for a short drive.No more squeak squeak...I am still going to do the driveshaft u-joints.But because of the schedule that I am working I probably will not be able to get them until next month.I was a nervous nelly expecting something to go wrong.I got a couple of small things I need to do before CFC.It felt great being able to drive Ol Blue want to thank everyone again for the advice.Thumbs Up.
