306 noise when cornering - duggie
my lad has just bought his first car a pug 1.4 306, the car runs well enough but we have some problems to solve, first one is when the car is cornering a knocking noise can be heard from the front of the car, lve checked the wheel bearings - no play and the wheels spin freely enough with no apparent noise, l then jacked the front of the car up and turned the steering from side to side there is a knocking/grinding noise coming from the top of the suspension mounts one side louder than the other, could this be the noise when driving the car? any help and advice appreciated.

I believe the 306 suspension struts have bearings sandwiched between the strut and the chassis/body. This should be seen to, but probably not the cause of the cornering knocking. That is probably worn driveshafts.

I would tend to disagree,all Macpherson struts have a small ballbearing race at the top to allow the strut to swivel.If these are worn the strut will move up and down,only by a small amount,but enough to make a knock.Very slight wear may only show up when cornering as the load is thrown to one side of the car.Worn wheel bearings generally make a rumble and worn CVJs,the ones on the hub end of the driveshaft,click when you turn into it,i.e.worn on left clicks when you turn left.
Try jacking up a front wheel,make sure the car is well supported,and get a long bar in such a way so that you can lever the strut upwards.You may be able to feel play in the top bearing,or see it if it is excessive.

Yes, I think its the bearing at the top of the strut. I had a 306 with this problem. Additionally, the defective bearing in my car would make a noise as the steering was rotated from side to side.
