weird knocking noise

[nismo racer]

just recently i was driving to pick my girl from thousand oaks and on the way back i hit a damn pot hole, but nothing happened. i pick her up and on the way back i beggin to hear this knocking noise from the front right wheel i pull over and check it out and i see a tie rod is bent soo i hobble back to my house and leave it, i change out the tie rods and it still made that noise. i checked the coilovers, double checked the bolts and made sure everything was nice and tight and still that knocking noise continues. the sound it makes is as if the wheel is wobbling and is very apperant when i turn into drive ways or go over bumps. also i lifted the car up and looked under and saw nothing out of the ordinary.

anyone know what it could be?
