i have put on a new set of tires and had the 4 wheels balanced. The car still shakes a little. What could the problem be? This is my first corvette I've driven. Do you normally feel everything in the steering wheel?

 

The C4 does transmit all the bumps, cracks and uneven surfaces back to the driver one way or another. Wouldn't describe it as a shake though.

Consider having the wheels looked at to be sure none are bent. It's possible that the tires are still out of balance. If your alignment off that can contribute. How about the brakes, any pulsation in the pedal? Badly warped rotors might feel like a shake.

 

If your tires are balanced, wheels bend free and alignment is dead on, then I'd start looking at suspension components that are worn or loose.

 

Is the shake visible if you take your hand off the steering wheel? I'm trying to understand your definition on shake? Is it something that visibly shakes or a vibration you can feel? FYI, I posted earlier with old tires there had been on my 89 since 1994 when my dad bought the corvette. My new set of BFGoodrichs really made a difference when I changed them last month. Most all of my vibration is gone. Its a convertible though so due to the less stiff vehicle I can feel things more than I did in my 1984 Targa Top corvette I had back in 1986. I think its just due to it being a convertible but then again in 1986 that car was almost new. C5 was redesigned to further improve convertible isolation of vibration by increased stiffness. My C4 has the extra added x brace but not a full fix. I like mine none the less but the conv seems diff than the old targa top to me. Not sure if yours in a convertible or not. 13,000 miles though should be in good shape. I would take it to a diff tire shop and have the wheels rebalanced. Does the shake dependent on speed? If you add or lower air pressure does the shake change? Does it shake when going straight or when around a LH curve or RH curve? Does it shake more or less if you go to neutral at speed and coast? Any of these might give a clue as to what part of the vehicle may be the cause? Maybe have it put on a rack and look it over underneath for clues of looseness or damage? There are some weird things like if someone changed a U joint in the driveshaft or in the rear half shafts that might cause some minor out of balance if not matched up when reinstalled. The drive shaft main is typically a balanced part. Someone could have thrown off the balance in a prior repair but thats unlikely at 13,000 miles. Good Luck. Any other clues you can give might help? To quit guessing if you could measure the frequency of the shake in the steering wheel and match it up the other frequencies such as engine RPM or wheel RPM etc, that would be the logical way to do it. You can do that a bit by checking the things I mentioned but not sure how to do it with equipment.

 

Did you fix or replace the bent wheel??

 

please tell me you didn't put the bent wheel back on.
