Hey everyone, Ive got an 07 mazda 3s, and almost at 200k. I have this noise that I believe to either be a bad strut in the front right or motor mount... the mounts are not broken but the rubber lining? I guess? Is starting to crack. I have a lot of engine noise in the right side of the cabin, only when exccelerating and mostly in 2nd and third. I dont feel it in the steering wheel or outside. I also have a rumbling feeling/ sound when idle at stoplights sometimes. It stops if I either release off the brakes or am in anything other than drive. Any suggestions???
