Default 1975 Corvette Chirp / squeak

I have a squeak or chirp coming from the drivers side rear wheel.

The faster I go, the quicker the chirp/squeak. This occurs regardless if I put on the brakes. However, when i apply the brakes, the chirp/squeak sound is more prevalent. It has rear disk brakes.

I replaced the leaf spring and bushings; however, the chirp/squeak is still there.

Any thoughts on the issue?

Most likely one of the u-joints: cheap and relatively easy to replace.
IF NOT:
Could be one of the wheel bearings (inner/outer): not overly expensive but considerably more difficult to replace.

Should i just replace the U-joint only, or is it wise to replace the entire axel? Also, if you replace one side, is it recommended to replace the other?

There are 2 u-joints per halfshaft so 4 u-joints total if you want to do both sides at the same time.
I'd minimum replace both on the squeak side. Generally, if the u-joint is bad you'll know it when you take it apart (rust, dust, dry, worn, etc).
While you have the halfshaft out you can check the axle.

I had a similar sound from the L/R on my 75. Found there were NO emergency brake shoes there..................




Good Luck,

Bill

If you have Rally wheels and trim rings, remove the trim rings on the rear wheels and see if the 'chirp' goes away.
