In July I purchased a 2009 Dodge Challenger R/T automatic with approx. 94K miles. It now has around 99K miles.
There is an odd rattle/clunk that comes from, I believe, the right rear of the car. It only happens over bumps or rough spots in the road, and to add to the frustration, not every bump or rough spot in the road. You can hear it clearly with the windows down. It’s definitely a “metallic” sound. When the windows are up, you can hear kind of a dull clunk coming from the same area.
I believe the noise is related to the brakes somehow, because whenever you press the brake while going over a bump, the noises go away.
I took it to a shop, and they are convinced it’s the caliper pins, which is apparently common on a Dodge Challenger/Charger. They wanted to replace both right side calipers for $250. I declined, as I wanted to look at it myself.
So far, I’ve checked the following, with no luck in stopping the noise:
Brake pads are fine on both rear brake sides. I’ve applied grease to the caliper/piston side on both pads. I’ve also used a c-clamp to compress the right rear caliper piston in an attempt to “reset” it.
Right rear rotor appears to be fine, although I don’t have a way to measure the thickness.
I’ve replaced the anti-rattle metal brake pad clips.
The right rear shock/strut appears tight both at the bottom and top mounts.
The tension strut (or what I believe to be it) has no play, and best I can tell the rubber bushings are fine.
Earlier today I replaced the right rear caliper pins with brand new ones, new grease, and I also applied a little grease to the anti-rattle clips, where the brake pads are held.
I’m about at my wits end, as well as the limits of working in my garage. Everything appears solid, yet the noise is still there. Any thoughts or guidance would be most appreciated. Thanks!
