Default Perrin Front Bar on Wagon Question...

Guys,

Quick questions... I installed Perrin Front and rear bars on my '02 WRX wagon. I aslo went with Perrin Rear endlinks, and a Whiteline ALK. Front endlinks are stock wagon units.

First 2-3 miles of driving, I got a wierd clunking noise. It quickly settled until it only occurred when heavy, heavy Trigger-the-ABS braking.

After checking all the fasteners I could get to without redoing the entire install (That ALK was a pain in my posterior) I went out on a romp with my fiancee, following her Auto-X prepped Turbo Miata. The suspension made some REALLY odd noises under deceleration. Sounded like, I dunno, a loose backing plate (and I got a CEL, which MUST be totally unrelated). I was hearing a ton of scraping-like noises., but only while slowing, clutch in or out. I checked, everything looked OK. It seemed when weight transfer forward, there was a ton of constant whirring/scraping noises.

I followed the woman down a twisting bit on a two-lane road, with a vicous rough section. I really pushed it hard (like, siding the rear end at 80 hard).

After the road smoothed out, NO NOISE!

Question: Does the suspension need to "settle?" Did I just need to work it hard to get parts in place? Because I did the install on jackstands and not ramps were things wonky until they settled? I went back and retightened everything after the car was on the ground.

Two: The stock endlink bolts on the front anti-sway appear to be rubbing the bar itself. Would aftermarket Perrin front endlinks solve this? I am getting a sort of clunking noise like a bad ball-joint, but only when moving slowly. If I am not in a parking lot, I get no noise at all, everything is fine.

Any insight would be appreciated.

Thanks,

Phil

I don't know what exactly could be causing the sounds, but it might have something to do with the fact that you installed the parts with the wheels in the air, rather than on the ground. I doubt it would be that much of a problem, so it might be something else.

Did you remember to grease up all the bushings that came with the new parts? Did you grease the ALK bushings? I know it gets kinda noisy if you don't grease everything up.

Sorry I can't help anymore...

Good luck

Installing sway bar parts with the wheels off the ground does not matter - in fact it is the way the service manual says to do it. that you should do it on ramps is a myth perpetuated by people who fancy themselves engineers and don't understand how a sway bar really works.

Of course, without actually drving the car to experience the sounds it it hard to tell what could be causing them.... you greased up all the bushings when you installed them correct? it sounds liek some of the noises you are getting may be caused by dry bushings - although these sort of noises usually don't manifest themselves so quickly... There have been a few threads fro mpeople having very similar problems in the last few days, check them out, make sure you greased everything up well, and make sure all the bolts are tightened to the proper torque specs, and let us know if your problems persist

The answer:

The shop I went through made an error, and sent me a sedan front bar for my wagon. Since the sedan has a wider front track, the bar and the endlinks tried to occupy the same space at the same time, hence, bad noises.

I have since removed the piece, and have returned to stock up front. The retailer in question was nice enough to swap bars for me, instantly.

Thanks for the input, however.

(and, yes, I put moly grease in the bushings until it oozed out when I tightened the mounts.)
