I don't ever recall having a shimmy that could be seen not felt. If you can't feel it my first thought it was in the road.

I've never experienced an off balance wheel that couldn't be felt. Both my X5s need the rear control arms front axle replaced and the primary symptom is wheel shake when either slight braking at speed or just the right amount of crown in the road trying to force the wheel off the self centered caster.

To discount the control arms the tests are:

Medium to light braking from 60>50 or 50> 40 mph

Driving straight on a level road (least crown eg center lane of three) then drive in a gentle "S" in your lane. 1 foot back and forth is enough. Use just two fingers to steer. If the control rods are shot you should feel just 2-3 wiggles at moment the wheels flip from right to left over the self centered spot.

If you get a tiny wiggle reliably and especially if both tests are positive it's for sure the front axle rear control arms.

FCP euro has a great price on lamforder brand.
