I've had a knocking noise for about 3 weeks, i've had ball joints, wish bone, brakes, drop links, anti roll bars, bushers, shocks, and tyres all checked and there all fine, now it's starting to whine a bit so thats why i'm guessing bearings (if not then at least there done). Why do you think yours need doing are they just whining or have you had a knock aswell?
Just a rough idea £65 each for bearings from my local parts stockist, and i guess about 2 hours work at a garage about £40 per hour so I reckon about £210ish. I'm going to book mine in next week so will let you know exactly how much but different garages charge different prices for labour.
I'm getting n/s front done Tuesday, o/s is ok it's going to cost me £160 all in, i'm 99% convinced thats the problem although it's unusual for a bearing to knock!
Been in and had the bearing replaced today, knocking all gone, Happy Days.
