There is a rubber bushing in the lower controle arm that goes bad .They come in a pair for about 95 bucks the left one is easy to change but the right one requires the removal of the motor mount. You will also need a balljoint service tool to press out the bushings . If your not a mechanic you shouldn't try this one.
It depends on the kind of knocking.... I have had 2 vehicles with knocking. 1 was related to the heating system or ignition andould quit shortly after starting the car. The other vehicle which was a toyota 4 runner was in the engine. It also depends on how loud the knocking. May not be helpful but look into it.
It is under the passenger seat!
Bottom, front, passenger side of the engine.
mine doing the same when turning been to garage could be broke spring or strut top bearing .
rack and pinion
Wheel bearing maybe?
you may have a rod knocking and you need to take it to a shop asap
Inisde the front (passenger side) of the engine. It is driven by the timing belt.
Might be a bad cv joint
That sounds like a broken or loose strut assembly.
possibly hitting the front bumper
A knocking noise in the front wheels can be a very serious problem. The knocking noise could be caused by bad ball joints. Bad ball joints can slip off the tie rods and cause the wheel assembly to collapse. This problem should be looked at as soon as possible.
