Replaced the driver side front ball joint lower after noticing a slight knocking sound over medium size bumps and being told it was bad by Monroe. Going over large bumps feels like front left of car is sustaining heavy casualties. Some of the knocking sounds in the suspension in the driver side front have disappeared after adding new tires and an alignment. Knocking sound is apparent even when braking. Front driver side caliper has a bit of play, but should stiffen when braking which I believe would not produce noise or knocking from the caliper. Therefore, when hitting medium size bumps hear a knocking sound above the caliper possibly somewhere on the strut tower. Top mounts are new also. Front strut assembly is approx 1 year old. Could this be a stabilizing bar issue or warn bushing or loose bolts in the strut tower? Please help, rattles and bumps drive me nuts. Thanks.
See if you can bounce car and replicate the noise. If you can, you should be able to find it, and put your hand on it. Stabilizer bushing are a place to look, both at the lower a arm and on the frame. If you narrow it down to the strut, it will need to be replaced. The front trans mount also goes bad, try putting it in drive with your foot on the brake and give it some gas and see if the engine moves an excessive amount.
