Offside Rear Wheel Noise

[Tucky]

The car has just had a cambelt change as well as new oil, oil filter, air filter and plugs (Odometer has just gone over 59,000). The work was carried out at a local garage which is owned by a friend. I asked him to check the offside rear wheel as I sometimes get a knocking noise (I know this is a vague description) when travelling over bumpy surfaces, pot holes etc. He checked the wheel and has said that the "top link" nearest the front of the car looks like it has moved from its original location and is rubbing against the subframe. The offside looks fine, all three links, front, central and rear are in place. Could someone advise if this is the correct term for the part and where I would be best placed to buy one? The car is an 04 plate IS200 LE.

Many thanks

The car has just been back up the garage, my friend had it up on the ramp for a thorough check. Looking at the car from underneath and facing the front, the offside link bar nut is maybe 1mm to the right in comaprison to the nearside. They have checked everything and it is tight as a drum and does not rub on the subframe. One of the mechanic thinks the bar handles the tracking of the rear wheels and as such both sides might not be exactly the same in order to provide the correct geometry. I panicked a bit after the first diagnosis - but having seen it on the ramp there is nothing to worry about.
