How much play should there be in the rear wheels? I know theres meant to be a little due to the way its all designed etc

Basically over large potholes the n/s rear left wheel sounds knocks. Rear is polybushed, everythings tight and solid, brakes etc are fine, just wondered if there was slightly too much play it would make the knock noise everytime it hit a pothole/solid bump in the road?

cheers

 

there should'nt be any play in the rear wheel bearings!!!!

 

words

 

yes there should, just a tiny tiny amount tho. Its part of the design

 

Who told you that Ive NEVER heard anyone say theres ment to be play in a wheel bearing

I cant see it being a wheel bearing anyway if it only happends when you hit a hole if it was the bearing it would knock/rumble most of the time i would think. Sounds to me like a suspension problem

 

Carnt you try adjusting the wheel bearing anyway

Yes, that design of wheel bearing really is supposed to have a bit of play. Anyways. Doesn't sound like a knackered bearing to me neither.

However you could always tighten the bearing a bit. But only a tiny bit. Make sure, the wheel is moving freely afterwards.

 

if there is ANY play in the rear wheel bearings it WILL fail the MOT.
there should NOT be ANY play in them!!

 

Thank you! Everyone else there IS meant to be play, just a tiny amount, if theres no play it would mean the wheel wouldnt turn! Read haynes or ask any person thats actually touched a rear bearing! Yes the fronts are solid, but the rears HAVE to have a small amount of play in

PeterRST i have nipped the bearing up slightly (to the correct torque) and its still doing it. If the suspension turret bush(the big old thing) was worn do you reckon this could cause it? Its the only bush i havent uprated

 

er....... i think i've done a few in my 22 years as a mechanic

 

The play that your on about that it say's it "should have" in the haynes maual you would hardly be able to notice it would be like half a mm - 1mm if that If theres anymore than that then id say your bearings fucked but that wouldn't cause it to knock just when you hit a bump as i said it would knock/rumble most of the time when you were driving.

 

1mms still play isnt it, fecking hell, wont bother asking in the future

 

why not just jack the car up an give it a good o'l shake an feel for play?

rear shoky might be fucked, top mount....will take you 10 mins max to jack it up check for play an check all bushes!

you shouldnt be able to feel any play in the rear wheel bearing!

 

Mate no ones having a go at you just the way you wrote it sounded like you had ALOT of play and were trying to say the haynes manual said you should have were just trying to help mate

 

Yeah, that's much more likely. Could also be the damper itself or anything loose (fuel tank? brake bias adjusting thingy? fuel pump?)

Wheel bearings usually cause grinding or whining noises. If it's "knocking" the bearing would most probably have to be totally fubarred with centimeters of play in it.

And yeah, usually the play is hardly noticeable. You might be able to feel it, when the car's jacked up. I don't use torque figures for tightening the bearings usually. I'm surprised that there is one actually. I just tighten it very gently with a spanner and make sure that the wheel's moving freely.

 

Ok cheers, ill have a look at the top mount. I know all other mounts are alright as i polybushed them the other day. Fuel tank and pump are definitly secure and the shocks are all a month or so old so i hope its not them,lol

antony215 ok mate no worries, think i just got the wrong end of the stick

 

No problem mate


That's probably what it is if it's worn then it's lose and causing it to move to much hence the bang you get when you go over a hole.
