David which front sway bar end links did you go with the Hellwig?
I got the moog f150 end links, now you got me worried
It is nothing to worry about per say, just keep an eye on them. Mine were trashed rather quickly.
I got these for the front:

Imho, the problem is the Hellwig is so stiff and the bushings on the average end links are too soft, not to mention the strength of the end link itself. This causes a lot of movement in the upper part of the link which eventually ruins the bushings and goes to town on the bolt (first with metal on metal clanking sounds and eventually destroying the bolt).
I ran the Moog's for a few months and a couple thousand miles only. When I finally got tired of all the noise they made and removed them, the bushings were trashed and the bolt was bent! The noise they made was the bolt clanging against the Hellwig when I hit a bump or there was some articulation in the front suspension, like pulling into a driveway at an angle... Btw, this same issue would come up with oem end links too.
Last but not least, I did not want rubber bushings because of the deflection. I want as sharp and precise handling as I could get out of the suspension parts...
