This will be my first of many help threads I'm sure! I had some AP coilovers fitted to my 2000 TQS by a very experienced VAG specialist yesterday, very straightforward, no trouble with any seized bolts etc, however now I'm getting a very faint light knocking noise from the rear when going over rougher terrain i.e a bumpy gravel road - I didn't have this before and I don't get any knock when traveling on smooth roads at all. All bolts were triple checked and both axels were pre loaded prior to torquing up the bolts to stop bush stretch where needed.. it almost sounds like the knock you get from worn ARB bushes, only my rear bushes look pretty solid..
Any thoughts? I'm not really familiar with the rear end of a TQS, but I'm tempted to put some replacement ARB bushes in and see, but if its still there, are there any other common wear points, drop links etc??
