thanks for the reply. fluids have been flushed per the service manual and my alternator has been rebuilt at around 85K miles.

i know the delaer once told me to replace the steering wheel shock absorber but the vibration feels fine to me, didn't seem to be needed.

as for the timing chaing stuff, any tips on what symptoms may be a sign of time to change?

also can you explain more about the wheel bearings...thanks!
