I recently brought my 2nd Seat Leon a 2.0 FR tdi, since owning it i noticed the steering wheel vibrates / Shakes slightly at 70ish. Ive had 4 new Tyres put on it, wheel alignment and balancing done but it’s still there. I recently took it to a garage and they put on the ramp and couldn’t find anything underneath saying it all looked in good condition. I was wondering if anyone on here had any further ideas of what to check as it seems to be a complete mystery.
Might be worth taking to a specialist wheel alignment place. I hit a large rock that damaged the wheel bearing and the wheel. It needed aligning after repairs but they found that the new, Seat replacement wheel was buckled.
