anybody have experience in early 80s vettes? i got rear suspension problems. is there any common problems with these cars?
We have a '74, which should have essentially the same setup as anything up to and including '82. What's the issue?
well the car is an '81. when i take off the car squats in the rear which i thought at first may be normal.. but as i let off the gas while driving the rear of the car raises up and the car kinda swerves to the left a little...it could get a little dangerous depending on the speed traveled. i also have a steering issue. steering to the left is fine i guess but when i turn to the right the car acts like the ratio changes and shoots over to the right way faster than the left. this is my first experience with these cars and im kinda worried...
The car utilizes a transverse leaf spring for the rear. Over time, the springs tend to lose their arch and the rear end will get soft and squat. If you look under the rear, you will see a bolt on each side that attaches the spring to the trailing arm. These should be adjusted equally and there should be rubber bushings that sandwich each component. The differential cover acts as a spring perch and these sometimes fracture and break.
Your car may, or may not, have a rear sway bar. Check to see that a link or mount is not damaged or broken. My car somehow destroyed the sway bar and caused it to bounce up and down going down the road. The ends actually bent out and contacted the wheel. It was a bit of a mess.
Last thing would be your rear shocks -- if they are worn it may cause odd handling issues. Shocks sometimes seize up as well and that could result in the problem you described. Bounce the back of the car and see how it reacts. It should bounce once, maybe twice, and then settle. If it continues to bounce, the shocks are simply gone.
Also, FYI, the rear spindle set up on C3's is a bit of a pain, as is the e-brake setup. If you have a spindle going out or the e-brake (or even brake caliper) is hanging up this may also cause the car to pull to one side. Let me know what you find.
i will check it all out this coming weekend. and can you explain to me what and how to identify a c3?

oh that explains it lol
hahaha did you just buy it/get into vettes?
c3's are definatly my favorite, but they were def. not the best made/designed vettes of all time, i hope to get one someday and completely restomod it
this is my first one. its got its issues. the main one being the L81 engine sportin only 190hp lol....it runs great but its no Ls1. I drive it every day so im learning more and more about the car. its fairly clean. ill post up pics soon...
Ours was a bit of a basket case when I started the restoration. It needed lots of TLC, lots of new parts, and fought me every step of the way. Here are some recent pics of the end result: http://www.ls1.com/forums/showthread.php?t=121626
that is a good lookin car

Check out Al Knoch for door panels and such. I also order from Corvette Central as their prices and shipping seem to be a little cheaper than the other suppliers.
just trade me your ws6 for the vette...lolQuote:

well, passenger window motor decided to take a crap on me this morning on the way to work. figures it looks like rain. did i mention i blew an exhaust gasket yesterday? sounds like an old garbage truck lol.....i need to park this thing soon!
I replaced the driver window motor in our car last year. FYI: Autozone had the part numbers reversed. I ordered a motor for the driver door, and the part that came in was for the passenger side. Re-ordered the passenger side and received the correct part. Not sure if this has been remedied.Quote:

well sometimes the drivers motor freezes up on me and i have to take the panel off and tap on the door right where the motor is with a hammer and it will free up and work again. but i never had to do this with the passenger side. its getting annoying. im learning the hard way that this car is not practical for a daily driver. also sometimes have to remove the window switch and plug it back in in order for them to work. i may just buy new motors like you say and end this problem.Quote:

It is likely that your window tracks are pretty gummed up from all the crap the gets into the doors over the years. Would not hurt to clean and relubricate the tracks. Also, check out your rollers and squirt a little WD-40 on them.
As to the wiring, could be a loose or partially corroded connection. You may have a switch that is going bad, or the breaker could be overly sensitive.
so after my blowout saturday morning...i got a new tire. fixed my exhaust leak and my passenger window. lubed up the gear and tracks with silicone lubricant...seems to be working nicely. i know im slackin on the pics...ill be sure to have em up by tomorrow.:blah:
ok so this weekend i will be doing a few things to the vette...brand new dual exhaust with no cat or mufflers, new fan clutch and water pump, new brakes, shocks, and if i feel froggy i may order the cam, but i will not install it until i get a new intake manifold, carb, stall converter and all the gaskets that go along with this. i will try to get some detailed pics posted up of everything on the car so that everyone can see what kind of shape its really in. im kinda curious as to what lies beneath..(under the car that is).
