My 300e has a rattle in the rear left , i`ve had it now for 2 years,it`s sound is just like as if i had a loose dress rim, you know the thin tinny ones. It only happens when the accelerator is not depressed, coasting at low speeds over undulating surfaces or bumps, it`s definatly comming from within the wheel and has got me stumped what it is. I`ve replaced the rear bearings thinking it may be that but it still persists, just this tinny rattle like a dress rim or a loose baffel in the muffler.
Thanks for any help George
