Default 1977 newb suspension question

Hi! I am from Jax FL and my wife is still there while I am currently in grad school in Tuscaloosa. I just got a 1977 Vette as my daily driver... super solid car! Was on a bike and totalled it in Pcola returning for the fall. Rather than get a used Honda Civic with 80K on it, I got my dream car!

I got a sound in the back end 2 weeks after getting the car and two local tire shops in Tuscaloosa just say its wheel bearings. Well, it could be aggravating it, but It sounds more like a rotor brushing on the guard. It only happens on turns, and usually only when the rear end is lower than the front, turning out of a lot, or on some of the hills here in Alabama... a whump, whump, whump and then gone after the turn. The mechanics here don't want to deal with it and are avoiding me. Thoughts?

I live next door to a family that owns a shop.. they are super nice, Armenian, and drive nice Benzes and BMWs... they worked on my f150. They are offering to do the work... do I need to only find a vette specialist for this, or is this something a good mechanic can handle? Since I am in grad school, I don't have time or access to a garage myself, just my parking garage. I appreciate your thoughts!

I would find a shop that does Corvettes on a regular basis since the rear wheel bearing set up on them is different than most cars. In addition it could be a u-joint or other wear items related to the trailing arms or differential. Check with a local Corvette club for a recommendation.

Hi Billy,
Welcome!
First posts!!
And a 77 as a daily driver!!!!
If it turns out to be wheel bearings the person doing the work needs to have experience doing Corvette trailing arms, AND the necessary tools and equipment to it without damaging other drive train and suspension parts while they're working.
You really DO NOT want to pay someone to LEARN how to do this job on YOUR car.
Good Luck!
Regards,
Alan

Yeah, I had a local shop grease my rear bearings with a tool I supplied... the fellow that sold me the car and did the work on it said it might help and would be a quick way to find out.. maybe a hour. Well, it took the guy working on it all day and they charged me for it... hundreds to just grease them and it did nothing. So, I've already had someone back there trying to learn, sadly. I may see about changing the rear end fluid if folks think that might work.. they can do that. If not, will have someone look at it when I get it home for Christmas break in December.

FIXED! I took it in and had the differential lub done... immediately fixed! I told the seller and he was baffled because he said he changed it out himself and asked if they added the limited slip additive. The shop told me they did and used BP products. Whatever, they did it has completely gone away! Thanks for the suggestions!
