is it my CV axle or my wheel bearing...

[T2urtle]

i figured i'll throw this out there to see what others think..

my mother's 96 camry with 115k miles. i've done the axles on it about 3 years ago, i rebuilt them myself and yea. lately the has been making a screeching noise.

The noise is on driver side 100%. i pulled the wheel off and put the car in drive and listen for the noise. The noise is either coming from the CV axle or the wheel bearing. Its there the hub meets.

Here are my issues and why i think its mainly the CV axle.

1. CV axle boot on that side is torn and leaking, Just started not a lot of grease all over yet.
2. Driving straight down the road no noise or issue.
3. noise mainly happens when i make left handed turns. But the noise doesn't happen when i'm on the brakes making a left hand turn. ANYTIME i'm on the brakes there is NO NOISE.

This screech noise i'm referring to is what sounds like HORRIBLE metal to metal contact on brakes. But its a very low pitch.

The axle boot is torn so i have to replace the axle regardless but while I'm there if the wheel bearing is bad i might as well replace that too.. To me to symptoms don't really seem like the wheel bearing but i cant be 100% sure.

What do you guys think? Just the CV axle?

You said this happens while braking?

Typically a wheel hub bearing going bad will be a dull grinding sound that gets worse the faster you go (obviously as the wheel is spinning faster).

Are you sure you just don't need to replace the brake pads?

its the oppsite. while braking there is no noise, say i'm going into a turn the 1st part of the turn is slowing down and braking, no noise is happening and while i'm acclerating out of the turn the noise is happening.

I can use the brake as a off switch the noise at any given time.

The brakes i've look at pad material as well and there is some on both side of that rotor. I'm replacing those while i'm there anyways along with the axle. Brakes i would say compared to new pads its about 30% left. Good enough material to not make a noise. rotors are no grooved up.

See if you can wiggle the tire/wheel vertically with the car jacked up. It sounds like you have a rotor rubbing on the caliper mounting bracket. If it's that bad, you should be able to detect a lot of play when wiggling it.

I think once you get the CV shaft out, you'll be able to tell if the hub and bearing assembly is worn out just by spinning it. Although I'm assuming you're planning on getting parts together prior to taking everything apart.

^yes i wanted to gather everything that i can do on my own before i start.

mainly front pads and rotors and Drivers axle. I cant do the wheel bearing by myslef.. thats why i'm asking now. if it is indeed the wheel bearing i might just pay someone to do both axle and wheel bearing since its the should be the same cost.

 

[T2urtle]

no thoughts on this... i'm shopping around for an axle right now.

oh yea, if i didn't state it before, the noise when turning left its not a always happening type of noise. it happens often enough to be annoying but there are turns where its nice and quiet.

 

[mizzou]

if you can wiggle the tire when its jacked up, that means your wheel hub bearing should be replaced STAT


Good luck getting the thing off, it can be a huge pain in the #%%

 

[fbrdphreak]

Yeah, you need to jack it up and try to wiggle the tire. Compare to another wheel to see how much additional play it has.

I doubt it's axle. Typically axles make more of a clicking noise, although I suppose far gone enough you could hear screeching.

I had a similar issue with my 97 Legacy wagon. It actually had a metallic noise, first only really audible during turning. My gf was driving the car exclusively at the time, so I only got to hear it when I was trying to figure out what was wrong. I had a mechanic friend look at it before she met me down in FL, 1000 miles away from her. He didn't see any issues with the axles and sent her on her way.

A week or so after she got down here, the noise was getting worse. As we were pulling into the parking lot of the shop I was going to have look at the car, I was hearing this horrendous metal on metal screeching as she drove by, from within my car with the windows up.

They looked at it and the bearing was trashed. The bearing was so bad, the hub shifted and the rotor was grinding into something, I forget what. The rotor and my ABS sensor were trashed. New front rotors & pads + new right front hub done by the shop to the tune of $900, which included a couple hundred to drop the steering rack and replace some leaking boots while they were at it. I got the ABS sensor at a later date and replaced it on my own.

Of course even though I told the guy to use good parts for the brakes even if it cost more, a few months later the brakes were pulsing as if you were driving over speed bumps. Just replaced those, thanks dbags A waste of money paying them to do all that, but we had just moved and I didn't have any of my tools or anything down here.

any updates on this? i have a similar issue and it gets louder when turning. Could it be my axle assembly? How much would a complete axle assembly set cost now a days? Im leaning towards the ACEI parts.

 

[kornphlake]

Most likely a wheel bearing, if the axles need to be replaced anyway it will be pretty easy to feel any roughness in the bearing spinning it by hand once the axle is removed.

 

[T2urtle]

it was the axle.

I picked up a reman axle at napa for $55-65 after core exchange and everything was all good.

hi, i came across this thread via a google search when trying to diagnose my car. does it sound like this? (i know this thread is 2.5 years old)

typically when working in this area you may hav bent the bottom of the dust cover allowing it to rub the bottom of rotor..it will give a mean metal to metal sound..you can just take a screw driver and bend it bak or hammer and lightly tap it..I just replaced my driver side axel and put in new bearings wen i put it all bak together i noticed a real bad sound metal on metal sound..a mech pointed out that my dust cover was bent and there were rub marks where the bottom of rotor was hitting...but now i hav to replace other axel..i dont think the driver side was wut was bad now.....but try the dust cover i cudnt believ it was some thing as easy as that..

thanks for your reply.
it turns out to be my brake pad. when i checked the pad, it had a lot of meat left, of course i only checked the outter pads. the inner pad was wearing thin - causing the rotor to rub against the warning tabs on the pads. what a noob mistake :-\
