BC Coil Over Clunking Sounds

Whenever I hit a bump in the road the right back coil over makes a clunk sound. Is this something I should be worried about or is is it semi normal for it to make that kind of sound?

That's a common problem. I don't think there is a fix.

It's semi normal. At worst, you're not damaging anything. I've got BC's, and I don't have any sound, but there are numerous reports of them clunking. Some members have found that adjusting the preload helps.

Disturbingly common.

This 18 page thread will notate many people's struggle, with one person resolving their issue in the quoted text:

This weekend I got the time to once again, pull lug nuts off. This time to replace the rear shocks that they finally shipped me.

The Short story: noisy, rattling, creaking is GONE!. The shocks themselves, not anything else!!!, were the culprit. Not an install error. This noisiness, btw, was from the initial install. Not gradual.

Of course, to get to this point, in the eyes of BC RACING, I had to jump thru virtual hoops, etc, etc. I tried to deal w them thru PM's to keep my mouth shut, if they would just refund my money, only to be told "they dont give refunds on USED EQUIPMENT!" (Used? Really? That one really got to me.)

So...... their defective products will go back to them today via UPS. Every company has defective merchandise....... thats NOT what my complaints are. Not at all.

I wouldn't be writing this if they had been upfront, professional and conducted themselves accordingly. It was all the negative finger pointing and accusatory so called "installation errors" and many emails and VM's that weren't ever answered. Weeks went by..... nothing.

My personal opinion for anyone looking to purchase coil overs for their cars...... is to look elsewhere. I wouldn't want anyone else to go though what some of us have...... and still are.

Hope they stay quiet.. Worst $1000.00 ever spent.
