To try and cure it i have replaced, front n/s shock and strut top front o/s shock and new strut top front lower engine mounting top middle engine mounting both drop links are solid and are the anti roll bar bushes both track rod end joints are fine,i have had 5 people look at it on diferent ramps. we put it on a single poster and jacked the wheels up seperatly to try and trace it but no such look we then put it on a four poster and removed the wheels,spending a good 30 mins with a bar on every joint we could find but nothing moved an inch!,,im going to set fire to it tomorow if i dont find the offending part:(, my e-mail is ahartwell@hotmail.com and my phone number is 07790 845 975,,,,I HAVE SPENT A FORTUNE SO I AM NOT BOTHERED IF SOMEONE WANTS TO CHARGE ME FOR THE AWNSER,I WILL PAY THROUGH PAYPAL IF REQUIRED.
