a knocking sound has suddenly appeared coming rom my rear sways i think. this happen to anyone else out there?

 

Knocking noise? From my experience, if it IS coming from the hotchkis sways, it's gonna be a "creaking" or a "rubbing" noise. It's most apparent when you're going over speed bumps or taking on an incline (like a driveway)

It's from the bushings. Whoever installed your sway bars, didn't lube it up enough with Lithium Grease. It needs to be laid on there pretty damn thick.

When does the sound go off?

 

i can hear it whenever i turn. i installed it myself so i guess its possible i didnt put enough. but i thought i put alot. since it was an amateur install i suppose there are alot of ways i could have messed up

 

I'm not sure if this would work for the g35s, but white teflon tape instead of grease worked well on my Acura TL-S Comptech sways.

 

Also check the torque on your swaybar links. If they are not properly torqued they could make that clunking sound. Just my .02
