Car's been audibly rattling a lot at low/high RPMs where the engine is shaking the most (cold, on the freeway/above 55 MPH). Looked under the car and found the alternator hanging fine...minus the lower through-bolt.
Second time I've had problems with alternator bolts; about a month ago the upper bolt kept trying to back out after loosing the nut (didn't get sheered off by the fan, thankfully). That time I just took a spare nut from a bad starter motor and stuck it on there (perfect fit
). Now I need a new bolt+nut. Anyone wanna take a guess or give an exact measurement of it? Should be something I can just pick up at a hardware store? Or do I have to pay $2.00 at PNP just to (try) and find one?
Also, good or bad idea using threadlocker on these...?
