Vibration

Seat Leon 2005

From the first day I got the car, it has been vibrating at certain revolution ranges. The tires, transmission and flywheel, but the vibration persists. I've been taking it to the mechanic for 8 months but no one has yet found out the failure. They are now telling me the gearbox needs to be replaced, but I do not trust them anymore, so I doubt that is the problem.

Hi, your vibration problem has nothing to do with all the parts that have been replaced in your vehicle. What must have happened is that, at some moment, when changing timing belt, a wrong tool was used to release the screw that holds the crankshaft pulley, and the screw was tightened, causing more pressure on such pulley. As a consequence, the crankshaft axis twisted or was left off-centered, producing the engine vibrations, especially at low revolutions. In these cases, you need to replace the crankshaft or try to straighten it up, which is a bit hard unless you use a lathe to rectify its balance. I hope I was able to help you with my comment.
