Hi Everyone, As you can tell by my profile and low post count, I am a newby to this site. I have just recently purchased a VS S1 Exec Sedan with 168,000km on it. It's in great condition...drives nice, etc ,etc. However, one thing that is really niggling me is a vibration upon acceleration, through to about 35/40 km/hr. I can feel the vibration through the steering wheel and gearshifter. I know I need to get a wheel alignment ASAP as it pulls to the right a bit, however I get the feeling it's something to do with the drive train, as rolling down a hill from 0km/hr does not cause this vibration, nor revving the engine in neutral. This site has been a great and impressive source of information and initial reseach has led me to want to investigate the Uni Joints (I believe there are two of them between the gear box and the diff (?). I am getting a workshop manual ASAP (I prefer Gegory's, but is it the best?), but I'm wondering if the symptoms match to Uni Joints, and whether there might be other issues, such as rubber bushes on various linkages (can anyone expand on the bushes info? Such as how many there are, what their proper names are, should I replace them anyway, if so, what do I ask for at the shop?) Also, in Sydney (North Side) what are the best shops for these sorts of parts? Autobarn, Repco ? Thanks for reading my long winded post...I hope I made myslef clearer than by writing a short confusing one.
