Having just had some nice new tyres put on the rear of my '96 Chim 4.0 I had them check the brakes - to my surprise they said that they are OK!

Just recently my lovely car has developed a chirping type of noise from the rear. This 'chirping!' gets faster and slower with the speed of the car and stops whenever I apply the brakes no matter how hard or soft. I have also noticed that when cornering to the left it reduces and if I corner hard enough it stops then sets off again when I straighten up. I think it is coming from the rear left (as if you are sat in the car!) never did get to grips with off/on side!

If you have any suggestions please let me know - Thanks very much

James.

It may seem obvious but make sure the wheels are bolted on tightly. You could have a wheel balance weight catching on the rear brake/hub assembly/caliper or a big stone stuck in the nice big grooves on your new tyres. Always check the simple things first!

Otherwise it could be something in the brakes/handbrake mechanism or the wheel bearings (although they usually don't chirp).

Thanks Trefor

This has been happening both before and after the new tyres were put on so I guess that rules out the tightening / wheel weight. I had the garage blow all the krud off the brakes and have a thorough look around but no joy - I must stress that this was a tyre garage not a service center.

Cheers.

I had a slight hum (no pun intended) alongtime ago on my 2.8i Special Capri (no jokes please) and it was the bearings. My old man used to me a motor mechanic and he showed me a way of checking which was as you go along pull the bankbread up slightly, if the noise went away it was the bearing as the added presure took the strain out to the worn bearing.

Just an But failing that seek professional advice.

Not too sure about what you mean by chirping but if it is the type of noise that could be caused by a loose pad touching lightly then it could be caused by a loose wheel bearing on the side the noise is coming from. That being the case it will go if you apply the brakes or go round a corner which from your descrption ties up.

The easiest way to remember near side V off side is that when the car is parked on the correct side of the road facing the correct way the near side is nearest the kerb.

Before I say anything:
Disclaimer: Although I have bits of paper that say I'm an engineer, my advice may not be worth the pixels that are displaying it....

Wheel bearings tend to get noisier the more worn they are. If it's an occasional noise then not much to worry about, just don't plan a trip round Europe or a track day. If it's a noise and you can feel a vibration, I'd get it checked out soon and limit the use to shortish slowish journeys.

If a bearing does fail it shouldn't make the wheel fall off, but it may well knacker the hub by overheating it and your repair bill goes up.

They're about £80 per side fitted so not too bad. If the hub is scrap it will be about another £80 - good old Ford bits.

James,

Assuming the guess is correct in the first place(?), a loose wheel bearing is the sort of thing most people would worry about. The problem is probably just that there is too much play in it and which case it can go on for a good while. Cannot put a mileage to it but it would not stop me from the Curry and Beer route.

Now what was that song............."three wheels on my wagon and I'm still rolling along".........

If you think the bearing is worn, jack the car up that side until the wheel is off the ground by about 3", spin the wheel by hand, usually if the bearing is worn you will hear a hum or drone, also check if there is play within the bearing by placing your hands on the tyre at a quarter to three and three a clock and twelve a clock and six a clock there should be no bearing movement when you do this , if there is then the bearing is most probably worn , also check the brake pads and disc as these rot like there underwater, the pad coming into contact with the rust could give a chirping sound when rotating, if so take the pads out clean up backs and sides with wire brush and refit with a dab of copper grease to the back of the pads to stop them squealing. if the rear discs are fd they are cheap to replace around £20 - 25 for a standard pair. I've just changed mine make sure you get a tool to wind the bd things back in and spray past the rubbers with WD40, Bd job when things don't want to go back in bloody 2 BD hours it took it get them winding back in, if you can't get the tool a 4 1/2 grinder disc release tool will do the job.
Sorry about the language blame the Stella. Hehe !

Qube - I'm on the cheap stuff from Tescos which is not working so well, but I'll get there soon....

Anyway - small point - better to use the Rubber & Nylon lubricant stuff you can get from Halfords when lubricating anything near rubber. Seems to work just as well on non-rubber and doesn't rot it away. I've found the stuff doubles the life of an average CV boot, and actually quietens down suspension bushes. I love it!!

or it can fail and lock up the wheel and dump the car into the scenary... If it is that get it fixed. Cheaper thn writing it off.

Thanks all for you're help. I jacked the car up and the wheel is indeed wobling and as it does so it chirps/squeeks etc! so I guess its a new wheel bearing for me. I had the garage look at the diff a while back as I was getting a whiring from the rear of the car - I wonder if I'm going to kill two birds!?

BTW the beer was Adnams and the curry was by fantastic - pass the frozen loo roll!
