Default is a clunking sound normal after sway bar install?

there wasn't anything at first, but today as I was going over some bumps, it started to clunk. I just installed cusco sways over the weekend (big thanks again to ricewagon ) Went for the usual testdrive after, and everything was kosher.

But, when turning hard to 1 side and going in a circle, there would be a slight rubbing sound. We checked under the car again and there doesn't appear to be anything that looks like it is rubbing.

And now the clunking, I'm just wondering if this is normal?

TIA

could you have installed the bar upside down? when i installed my RT bar upside down it would rub on the lower control arm when i turned the steering wheel either way hard and got the odd clunking when going over speedbumps.

the ends of the sway bar should go under the lower control arm instead of over. i might still have some pics for visual aid if needed

Aside from making sure everythings still torqued down to the proper spec (important!!!), look for any signs of rubbing or wear on suspension parts.

My front sway bar rubs slightly on my tie rod when I'm making a very specific maneuver, I wouldn't have figured out what it was unless I noticed the small patch of paint that was rubbed off.

i didn't torque down anything, I more or less elbow torqued it. Do you know where I could find the proper torque specs?

There are no signs of rubbing, thats why I'm totally clueless.

I'm pretty sure I didn't install it upside down. But I better double check.

Pretty sure that an installed strut tower bar should not have any clunking sound. there are no moving parts on it

The kit should have come with torque specs on the instructions.

An overtorqued mount, for instance, could cause the bar to bind up and move in big jerks instead of smoothly.

I have a Whiteline rear sway bar. When the car's on the ground, there's slightly less tension on the endlinks then when the car's in the air.

I have the 'fat' Whiteline endlinks. They jiggle in their brackets when going over small bumps. Normal in my case I guess. I'll eventually get around to getting some of their 'skinny' endlinks...

the stock endlink in the front was just pathetic.

the only english part says "these parts are made for japan only, it must not be used in any other country"

Dude, you need to torque those nuts down HARD or they are going to clunk like no body's business!

I went through this when I did my Whiteline sway install... Couldn't figure it out for the life of me....

I then replaced every single nut and bolt and torqued the crap out of them...

And oh sweet silence!

Also check your brackets that are connected to the frame. There were some nuts that were loose on mine that made the bracket move around and clunked... I kept thinking it was the endlinks....

Also you may have installed the end link on the wrong side of the sway bar?

Just ask Jay at Dale's he see's this all the time!

+1 for "Dude, you need to torque those nuts down HARD or they are going to clunk like no body's business!"

I put 1 inche sway bars (by hotchkis) on the front and rear of my 04 and the drive initially was quiet but by the next morning they were clunking while drving straight. I talked with a service tech at Hotchkis and he recommended to tighten them right down and ignore the torque specs assigned. When the bars are created, the holes are made a little large to accomadate different setups so the torque is an unknown variable or recommendation.

So just crank down but be carefull not to break anything.

funny how the clunking now is gone

Either way, I'm going to get at it and torque it down. I'm pretty sure they are on right. I'm going for an alignment on Sat anyways

Japan's gravity must be different !!
