Hi all, basically as it says above. When driving my '91 cooper, if I turn left I get a grinding noise, sounds almost like when your breaks wear down to metal on metal, but under right hand turns and straights all is well.
I have checked the wheel bearings, 3 sets are brand new anyway, the rear radius arms are perfect and have no play, there is no play in any bearings or hub ect, and all the brakes are new. The car has only just been put back on the road after a years restoration.

So basically I suspect the diff is at fault, so firstly do you think this is right and is there a way to rectify this with shims perhaps between the output shaft cover plates, or is it just a case of bite the bullet and engine out?

Any help would be fantastic,

Cheers

You need to check c/v joints before you start on the diff

We'll when I replaced the gaiters as part of the build I cleaned, checked and re greased the cv's, although saying that now they have done a few miles it can't hurt to re check I guess?

Thanks for the input, I'll have a look at this before I do anything drastic lol

yea id agree with the above :) also, and this is a bit obvious but, could it be something sticking in your spokes or your tyres rubbing on the arch/inner arch/arch liner/random piece of metal that shouldn't be there

Greasing up your CV joints wont help if the actual metal of the joints are worn which is very common.

wouldn't a cv click more then grind? id suspect wheel bearing for a grinding on a turn.

That's why I haven't checked the CV's, I always thought you get the characteristic 'click click click...' as you turn when these are worn, I have never came across one that grinds. I will have a look just to be on the safe side.

Have you got the old stone guards fitted behind the discs?? any damage to them at all??

[lsto]

Yeah the back plates are in place, I checked these and they are fine  Not touching against the disk...

 

Thanks for the suggestion tho. Any help is greatly appreciated!!
