| Weeksys idea is a good one. Swapping the wheel will point the finger at either the wheel or the chassis being the problem.
Why just change the rh wheel bearing though? Personally I only change them as a pair. If ones gone, and they've both done the same mileage, the other won't be far behind.
When's it juddering? On the brake? all the time? Are any of the pistons sticking in the calipers? |
