knocking sound coming from the passenger front.

sounds like bad control arm bushings possibly.

knocking is usually associated with bad bushings, bad ball joint or bad bearings. all have different variations of "knock" sound.

youd hear a whirring sound at speed and a clicking at very low speeds if it was a bearing. if it was knocking, ud be in some smelly brown stuff (ask me how i know).

ball joints click and/or knock when turning or during suspension articulation, so its possible but if you already checked then ur fine.

bushings will present a heavy knocking noise, especially when compressing the suspension, depending on where the bushing has cracked.

ive had this happen a few times, and normally they arent hard to replace.

the other thing it may be is sway bar bushings so check them too.

if its the bushings, get a prothane front end bushing kit. itll stiffen up the front end nicely and last longer than oem.
