Hi all...

Lately i've started to hear a chirping sound coming from the front left wheel. My thoughts were either wheel bearing or dust cap. It only occurs when the wheel warms up, after 5-10mins of normal driving and gets worse as it goes. I sprayed the dust cap with a bit of WD-40 but it didn't change anything.

It sounds like "chirp, chirp, chirp...", not a sqealing sound, its not brake related. Sounds like a bird has nested in my car.

The magna specialist in town said he's never had to change a wheel bearing on a magna before... and that they're generally pretty bulletproof.

Anywayz... i'd just like to get some input on this, coz if it is a wheel bearing i don't want it to get much worse. Cheers.

could be a warped rotor maybe ??

Thanx for the input, but its definately not brakes... i just replaced my front brakes. Calipers, rotors, pads & backing lines.

The sound doesn't change with brake application, or engine speed. Only with vehicle motion. It starts making noise at around 10km/h and becomes louder and faster as the speed increases.

Sounds like a bearing...regardless of if the mechanic hasnt had to change one, that doesnt really matter. What you've described is the same sound I heard when the bearings in my old meteor went, and the when the ones went in my old man's laser.

Rear handbrake shoes? Remember reading something like this while experiencing the same problem in my 3rd gen. Don't know if the same rule applies, but it has something to do with the handbrake not quite disengaging.

Can you only hear it at the particular speed because ambient sound increases with increased velocity or the sound is linear with the speed?



edit: sorry just read it's linear with speed increase, sounds like rear brake shoes IMO. Only difference is its a whooshing sound and not a chirp. (slip of wheel sound)

Its either the wheel bearing or a warped rotor. Regardless of whether you've just had them remplaced. Its not uncommon for rotors to be warped even before installation and very easy to warp glazed rotors with brand new pads.

I'm with killbilly though, just because they arent a common issue doesnt mean that your wheel bearing isnt going bad.

Oh and lastly, spraying WD40 on ANYTHING near your wheels is just plain stupid... they make a specific brake cleaner for such things that dries in a matter of seconds, unlike WD40 that'll stay on there and could possibly splash back to your rotors... have fun stopping when you're wheels are covered in lubricant.

Thanx guys... well looks like i'm gonna go with the wheel bearing... it was my first suspicion anyway. The sound got louder today...

Dpack, the wd-40 was just to lubricate the dust cap, i covered the rotor with a rag and made sure there were no drips... i still know what you're getting at though. Yes, the wd-40 could spray off when the wheel is in motion, but its nowhere near the ammount required to make the brakes uneffective. The reason i used the wd-40 was for lubrication purposes, using the brake cleaner would be stupid because, as you said, it dries in a matter of seconds, so how would it lubricate?

My car made this sound also and it was the wheel bearing :).

Cheers TR-Envy... now i know i'll definately try it.

Ok i found my problem after some poking around under the car today.

Just to confirm for others, it was not the wheel bearing; it's the driveshaft support link bearing. :cry:
