recently asked re anti roll bar drop links "knocking" and was
pleasantly surprised to find it wasthe ARB bushes that were sh@gged.
Duly replaced with heavy duty items a day ago.

However now I'm getting a "knobbly tyre on road" type noise *in* the
car at 30mph or above - speed related, but not engine related....

Can changing ARB bushes affect tracking for e.g.? or is the firmer
material of the HD bushes likely to be transferring more road vibes
into the "chassis" ? or something else??

Cheers
