Mazda 3 2017 2.0L
Just under 70k kilometers.
Our car started a vibration while driving after a front disk change. Went back immediately, and over the last few weeks the dealer tried everything they could think of, wheel balance, different wheels, redoing the disks, tried different disks, checked arms, bushings, wheel bearings... car still vibrates. You feel it in the steering wheel, but also some through the body. Rears were not worked on when the vibration started, but were later checked anyway, no fault found. Braking hard does change the vibration a bit, but the vibration is there while driving. Official Mazda dealer sent a letter to factory asking for suggestions because they are stumped. Does anyone know where to go from here or what do you think it might be? Thanks!
Well if it happened after disc change obviously something was done wrong. Perhaps they sold bad discs that aren't balanced and it's going to vibrate. But there's so many things that can go wrong when they put something back on. I've even seen them do that because the idiots tightened everything up too tight with an air impact wrench which then warp the new parts. So there's lots of things that can go wrong and a lot of times mechanics don't stand behind their work and they don't want to do it over for free and they'll just say oh we can't find what's wrong. If it happened right after you got his back they screwed something up
@scottykilmer Hi Scotty, just wanted to give a little update on the vibration. You were probably right about the overtightening, we had found that the nuts were way too tight and actually ruined some thread. They eventually changed the wheel bearings on the side with the most vibration and it helped a lot. It's not free of vibration, but the worst is gone. Of course, they wanted 2500 dollars for the whole job. Which naturally we told them to stick up their ***
Cheers!
