Vibration in Steering Wheel and Floor Pan
I just cannot seem to figure this out - nor can the techs that have looked at my car.
1999 Bonneville SLE, 150k, new front struts, new cv half shafts both sides, all other front suspension components either replaced (stabilizer pins, ball joints, etc.) or determined (by techs) to be ok.
Can has been aligned; tires balanced with about 20k on the tires. Tracks perfectly straight at speed.
When I am at low speeds such as moving through a parking lot, if I hit a small bump, pot hole or expansion strip in the pavement I can feel a pronounced vibration in the steering wheel and what also feels to be in the floor pan. It seems to me to be a problem with the driver side suspension.
Traveling at higher speeds (i.e more than 30 mph) the problem is not evident. I do get what feels like some rotor pulsation at over 40mph, or what feels like it. No pulsation at lower speeds.
It almost feels like a loose strut or a bad cv with a lot of play. All struts and half shafts were replaced and did not resolve the problem
Could I have a bad hub that would cause this? They are just about the only components that haven't been replaced. No humming coming from any of the bearings that I can detect. Very annoying problem that has me at wits end. Your help and suggestions greatly appreciated....
