So I’ve had the dreaded endlink clunking issue ever since installing whiteline rear sway bar and end link kit. Several times now, I’ve removed the end links, attached the top bolts first, then attached the bottom to the sway bar with the car on the ground on a level surface. Yet, over and over the bolts loosen - particularly driver side.

Has anyone had this issue? Maybe I should install new lock bolts. Why would they continuously loosen - maybe something is in a bind?

 

dump em and get these

I had to tighten the locking nuts really tight with lock tite.

 

Had same issue. Used lock tight and a locking nut (from hardware store) and tonnes of torque... lol.

It fixed it. I have tracked the car since and the end links haven't come loose yet.
