2008 GMC sierra. Just installed new quick strut on driver side, and now I am hearing and feeling a rythmic thumping coming from that side that I can feel in the steering wheel. it increases and decreases with the RPM of the wheel. it seems to get louder when slowing down and braking. turning has no effect on it. New tires were put on before all of this. the lug nuts are torqued to spec along with all the fasteners on the strut.
Any idea what could be causing this?
