It was posted in here and in another thread I believe, but if you have a RATTLE when going over bumps/potholes at lower speeds, IT IS NOT THE SUSPENSION.
It is the coolant reservoir rattling!
I had this annoying rattle for as long as I could remember AND WAS 110% POSITIVE IT WAS THE SUSPENSION...welp this weekend I finally saw a thread about sticking a sponge underneath the coolant reservoir and an AC line. Instead of a sponge I bought 1/2 inch thick pipe insulation. If I could have found an inch thick pipe insulation it would have been perfect, but instead I tucked extra material under the 1/2 inch pipe insulation so it fit snugly between the AC line and the bottom of the reservoir.
THE RATTLING HAS STOPPED COMPLETELY.
