Default After RSB and kartboy endlink install, loud and abnoxious "clunk"

I installed a whiteline 22 mm adjustable swaybar and rear endlinks. The sway bar is at lowest setting. I now hear a very loud and definite clunk sound specifically coming only from the right side connections. It usually happens when I'm making left turns but now it is starting to do it even more and more even after I tightened all the endlink bolts down. I tried searching but everyone has slightly different problems. The clunk sounds really unhealthy, and regular passengers can hear it almost immediately after the first clunk.

Anyone have any suggestions to resolve this issue?

Are you sure you got the right bar, and everything is torqued down to spec (bar bushings ~20 ft-lb, endlinks ~35 ft-lb)? Any chance the bar is hitting your exhaust? Can you see any marks on the bar or car that might indicate where there is contact?

Mine did that when the endlinks were loose. It was pretty loud. After they were tightened and greased properly, no more clunk.

Funny this thread came up. I installed the exact same setup on my 06 WRX and had the clunking also. I tried all suggestions - tightening, using a less stiff setting, etc. My problem was that when i put the U braces (the ones that hold the bushing) back on, they were backwards. I couldn't see the "-> F" imprint on them because of the muck build up. After I put the braces back on with the arrows facing FORWARD, no more clunk.

Hmm, I'll take these into consideration the next time I get under there. I didn't know there were torque specifications for tightening down the endlink bolts =(.

While under there make sure the muffler isn't hitting the bar. If it it then loosen the nuts and bolts on the chassis mounts, and shove the bar forward. there's a little bit of play there.

If you're still hitting the can then look into Tom@kartboy's stiffer exhaust hangers. Quite honestly folks should just start bundling them with new exhausts..... hhhhhmmmmmm.....

I'm pretty sure it's not rubbing or touching my exhaust. I have the long exhaust hangers from kartboy already.

Basically, the sound is coming from the right side and it is more of a sound like plunck, clunk, pop, type thing... yeah really unhealthy sounding. It now happens just over regular minute small bumps when the road surface becomes uneven in relation to both rear wheels. Before, it just happened when I turned ninety degrees or turned faster then slow. Anyways, I will get under there hopefully soon; I will let you guys know how things go though.

Im confused. Do you mean you greased the endlinks? I was under the impresion that endlinks like Kartboy that used the bushings didnt need grease. I know you need to lube up the swaybar bushings really good but I was told the endlinks didnt need any. If this is untrue though I guess I need to grease them..

I have the cobb rsb and kartboy endlinks. It doesnt really make any noise. I have some creaking but I think thats a combonation of the rear glass and the rear struts. I lubed the swaybar bushings really good but I left the endlinks dry.

FYI - there should be torque specs for just about everything holding your car together. If your aftermarket parts don't come with instructions, write the manufacturer to see what it should be. Too loose and you run the risk of it coming free or moving around. Too tight and you run the risk of breaking the bolt or moving things out of proper alignment.

You gotta torque down endlinks more like 45~50 lb/ft.
35lb/ft is for stock ones.
