Re: Knocking and Squeeking
front wishbones knock when the bushes fail, unfortunately you have to replace the entire wishbone, upper ones are not expensive, £25ish, bottom ones are up to £100 depending where you go. not a big job for a garage to undergo, few hours work.
the squeaking could be connected, the upper wishbone can cause a squeak, as can the anti roll bar. i would advise you get a reputable garage to check out the wishbones, its quite easy to see if they have failed as there will be excessive play in them.
best of luck.
