Well, I tried pulling up on the ebrake going over bumps and I think it may be making a difference. It's hard to tell if the bump was big enough to make the rattle sound so I don't know for sure if my pulling up is what's really stopping the sound. But anyway, I think I'm going to check on the ebrake...it takes a lot of clicks to get it to hold the car when parked so I think it may be that.
Can anyone explain to me how to adjust the ebrake?
Also, Billan, your car looks awesome in that pic.
