Newbie squeak question

Hi,

Newbie here. Been lurking for about 3 months. I'm pretty mechanical, but I've never even changed my own oil. But after reading threads here, I've now changed an axle u-joint, and put a new muffler/tail pipe on. So I'm feeling confident about working on things a little more now.

I have a '97 SE. We are having a chirping noise in the front end. It starts after driving for about 10 minutes, and goes away when I hit the brakes. It reminds me of a brake squealer, but the pads are like brand new. Any thoughts?

Thanks,

Mike

Hey Mike, how long have the current pads been on there and what kind of shape are the rotors in? Asking cuz a grooved rotor can wear your pads down quicker than normal I believe. Also a lower quality/cheaper pad will wear fast or start squeaking a lot faster than you'd think...thats my experience anyway. I'm thinking that since the squeak stops when you apply the brake either your rotor or pads, or both are worn down and could possibly need to be replaced. I'd take the front tires off and inspect the pads and rotors and go from there. If they're grooved or warped but still thick enough, the rotors could be resurfaced instead of replaced....

Chris,

Not sure. Previous owner put them on shrotly before we purchased. I think 3 months/5000 miles. How can you tell if the rotors are warped?

Thanks,

Mike

It might be what is called "Angry Squirrel Syndrome". Your front drive shaft has whats called a CV joint at the transfer case, this joint is in a very bad spot to grease so most people don't do it. It has what is called a ball & socket type of joint in it, after awhile it dries out and starts to do this annoying squeak that will eventually become constant.If the ujoints/socket is still original there will not be any grease fittings so you will have to change them out, when you do make sure you get the greasable type. I have gone as far as removing the entire driveshaft to grease the CV.

If it was the cv joint, would the noise stop when I hit the brakes? Definitely goes away with application of brakes.

In that case I'd have to say either a warped rotor or a caliper that is seizing which can also warp a rotor. Grease the CV anyway, if that thing blows it will take out your transfer case with it.

I'm pretty green. Will they be noticeably warped? Also, how can I tell if the caliper is bad?

Thanks in advance.

Mike

If you lift the tires and give them a spin it will not spin freely,you will feel resistance, you may hear a slight rubbing noise and the tire will stop at the point where the rotor is warped. When driving with a seized caliper the vehicle will tend to pull to the side of the bad caliper and gets worse when you hit the brakes. Eventually it will completely seize up, overheat and then you will smell burning brakes.

Thanks for the help. The caliper was stuck. Also decided to change rotors since they were only 20 bucks each. Squeak is gone.
