Help with problem on

I have a renault megane and for about a year mow and again I would here a funny noise from the underside of the car but had it on a ramp and could not find it, over the next few months it has got worse and tonight after more search I have found what is loose. Its the the hoop with the teeth in the picture. Anyone shed any light what it is and why its lose. Is it safe to drive etc. :confused:

should say its just behind the wheel on the ball joint. I'm sure it not a wheel bearing as I had it done not that long ago.

it is the ABS ring, as to why it is loose who knows, you'd have to strip it down and investigate.

Thats why my ABS Light is always on, should this have not been picked up on the MOT and also it was with renualt 2 weeks ago to go on there computer for another fault and they also checked the brakes and said they where fine :confused:

It shouldn't be loose, I would have thought having it welded in place again would be the only way to secure it, if not you will have to buy a new CV joint, although with many French cars you can only buy complete driveshafts.

So how does this work in relation to the ABS :confused:

moss · 6 May 2008 at 18:17

That ring is what the ABS sensors picks up (though magnetic pulses iirc) when the ring stops spinning it assumes the wheels have locked up and the ABS will kick in. If the ring has moved out of place, the sensor wont be picking it up which is why you have the ABS warning light on.

So its safe to drive then, I just wont have any ABS.

I cant imagine it causing any problems, just as you say, your ABS wont work.

What year megane? Trouble is as the ABS light is on if its got EBD then your brake balance will be all over the shop and greatly reduce the capability of the brakes as it just reverts to a 50/50 split.

Its a 1998 magane 20lt 16v, also what is EBD?

Electronic Brake Distribution, I'm not sure if you cars likely to have it though.

bmh.01 · 6 May 2008 at 18:37

Nope yours doesn't, it'll be fine. I'd get the ABS ring changed though.

Can I just get the ring changed or like good old reanult do I have to replace the hole engine and my girlfriend

I doubt you will be able to get the ring itself changed, its usually part of the CV joint.

bmh.01 · 6 May 2008 at 18:42

No you can get just the rings, they'll probably try to sell you a driveshaft though. If you can get me your oval plate details then i'll be able to find a part number/price for you.

Apparently they're very delicate and hard to replace without cracking them.

Have a look on ebay for the whole CV joint, probably only be about £25-£30

Can I just cut the old one off to stop the noise

, I know I will have no ABS but this is not a major problem till I get it fixed. Also why did this not get picked up by the renualt dealer when they done the check on the breaks or the MOT :mad:

Give that man a cigar, top job

I would have your CV boot (the black rubber part) checked too, it looks like some grease has escaped, you might have a small split in, I would expect that to be changed when the joint is done anyway.
