I think somethings seriously wrong with my rear suspension

I installed my Perrin RSB & End links about a month ago and noticed a "clunk" going around sharp turns. It only does it once though if you keep turning in the same direction. Do sharp turn the other way, and it clunks, but only once if you keep doing sharp turns in that direction.
Since it started doing it after I installed the sway bar, I assumed that's what it was. But I've checked and checked; even had it on a drive on lift, grabed the bar and tried to move it to clunk, and nothing. Nothings loose. The bushing in the endlink moves a bit, but I'm assuming a little give is a good thing there.
Now the car likes to turn better with the RSB and my new tires (KDWS's), but you still have to try to get the end to step out in the dry. I was driving down the street and did a right turn and floored it, got the end to step out a bit. Cool. Kept going down the street and came upon an "S" curve that I've driven over numerous times at high speeds. I was doing 45 and down shifted into 4th to have a little more umph going thru the turn. I shifted right as I entered the curve and hit a little bump and the car went way sideways. Luckily I caught it.
I'm a little nervous to drive my car right now. Someone said that he had a similar noise when he had a loose strut in his car and that the stronger sway bar may have aggravated it.

Any ideas?

What type of endlinks did you get? because I have read that the ones with spherical? joints allows the swaybar to walk which is not a good thing. Correct me if I am wrong fellas .... On the other hand your bolts might not be torqued down properly as in the thread below:

Did you put some type of grease or teflon tape in between the bushings and the bar? The polyurethane bushings give this clunking/ creeking sounds when load is applied to them (since you only hear the sound when making turns or going up driveways at an angle I assume). You're going to have to take the bar off the mounts, wrap some teflon tape around the area of the bar that the teflon bushings sits on, then re-intall them again. Make sure the bar is centered properly also. Good luck and hope this helps.

It's the Perrin end links.
I used all the grease they supplied with the kit (the whole tube). I don't think the instructions had any torque specs. I'll try to find them.

There is a tube of grease that is suppose to go with the Perrin endlinks? Can I use WD-40 instead?

Use the grease and make sure to tighten the bolts properly. A lot of that clunking noise could be from movement. Not using the grease could also make the noise, but this will increase the life of the parts.

I had the same problem

Today I finally removed the vapor box in the rear right hand side of the car. The metal mount that this box is mounted to is very flimzy and was making metal to metal contact. I took a saw and cut some of the metal away and re-assembled the box (it only has 3 bolts holding it in place). No more noize.

Check it out. It is making contact right where the tow hook is bolted to the body.
