alright, im a new supra owner as well as new to driving a manual trans car. the other day when i was driving i screwed up shifting from 3rd to 4th, i missed the gear, but it didnt affect driving. right after that i noticed a loud knocking noise coming from what sounds to me like the back left wheel assembly. nothings loose and ive had the car jacked up and nothings visibly damaged. talked to toyota and the tech said it sounded like coincidence that the noise started right after missing a gear. either way, the noise is coming from the back and not the engine, and only when i let off the gas. it shifts into gear fine and still drives fine, no loss of power, just feels like a bearing is missing or something because when i let off the gas i can feel a bit of a lag from the rear as well as the loud knocking noise. anybody have any idea as to what this might be? any help would be appreciated. also, its my bad if i posted in the wrong spot, im still new to SM.
