I need help or advice i recently installed some function 7 rear control arms it was fine for about 3 months but recently on hard turns i get this very fast popping noise from what i think is the right rear lca and also the car squeaks from the rear on bumps, i can push the car down physically and hear the squeak i uninstalled them and reinstalled them and no luck, i noticed that the side that is making the popping the shock for has no welded nut on it, so i put one of my own , i don't know if that could cause that noise?

 

Check your wheel bearing on that side.

Do you have a big sway bar installed?

Lug nuts tight?

 

Yeah lug nuts are tight its on the stock swaybar, and i jacked the car up on the wheel so i assume the bearing is good? Or is their another way to check it ?
