Hi Poster..
1st of all. The word for your issue is "Wobbling". Wobble or wobbles means to shake or wiggle and may also refer to: Wobbling effect. At least us guys i.e a bit literate bunch of car freaks should use proper words for the issue.
Secondly : Go to Al-Turbo Motors... Freeadvisor is mentioning the same woshop at queens road.. They are realy very good at balancing/ alignment/ adjusting cambers etc.. They,ll guide you properly.
