Guys, I thought I had posted on the front-end clunking fix; but couldn't find it in the archives.
Anyway, I posted several times last year about my new '08 sounding like the battery or the front wheel was going to fall out over rough roads or railroad tracks. A pretty heavy clunking sound and feel.
Well, I finally took it to the dealer, and asked them to check out the clunk.
They said the brake caliper pins were not sufficiently lubricated, allowing the calipers to click/clunk around when hitting bumps.
I was pretty skeptical, but I can report that after several months, it is definitely fixed! I rotated the tires last week, and sure enough, the caliper pins had been thoroughly greased.

Hope this helps anyone experiencing a similar problem.

I just changed the rear pads on mine. The pins didn't look overly greased. Do you know what kind of grease they used?

I always used this for my cars. I haven't done the brakes on my SRX yet.

G32, there was a TSB about it? I'll be darn!
I had read thru several of the TSB lists, but I guess the title of the TSB just didn't register with me if I saw it. But it's fixed, and I'm sure gonna use plenty of your recommended lube on a routine basis.

Tks,
DG

Would sure like the TSB number on this. My dealer says it was always like this. I installed new rotors and pads - thought it started after that, I do know that just a small amount of brake peddle stops the noise. Thought maybe I put the clips on wrong but hey are good. If there is a TSB# I can have them do it.
