<DIV><FONT size=2>Bump steer is different to vibration. Bump steer is when
the trackrods are not at the idle angle on smooth surfaces, and that angle
increases when you hit a bump i.e. compress the suspension. That
effectively pulls the wheels in or give more toe in. Bad enough if both
wheels go up by the same amount, but if only one wheel hits a bump only that
turns in so with the other wheel pointing as it was the car changes
direction.</FONT></DIV>

<DIV><FONT size=2>Vibration over a bump is something loose, or something
hitting something it shouldn't i.e. insufficient clearance somewhere, or
something worn i.e. too much clearance. If the damper bearings are badly
worn it could be them, but usually it is just the oil seals that go. It
could also be king pins, bearings, upper and lower trunnions, track-rod ends,
anything in the rack, the UJ, or the column. It could be that the problem
was always there, but the bump-steer from lowering the suspension has made it
noticeable.</FONT></DIV>

<P class=MsoNormal>I hope someone can help me. I have a 1980 MGB that has been
lowered with parts sourced from Moss Motors. Since lowering the car I have an
annoying vibration in the steering wheel whenever I hit a bump.</P><!--[if gte mso 9]><xml>
