Oh, thats a possibility I should have thought about. Especially as my backup car (old range rover) is currently in the garage awaiting a new donut after the old one failed catastrophically. It is a possibility for sure.

Hello. My 2014 Octavia 1.8 4x4 has developed a strange issue. There is a vibration coming from the rear of the car when driving. It feels like if there was severe unbalance, or a flat spot on the tires. I have however ruled out this possibility, by first having the wheels rebalanced, and then having the tires replaced. With no change. Symptoms: - Heavy vibration from rear of car. (No steering wheel vibration) - Can sometimes be felt from 20kmh. Frequency increases with wheel speed. - Vibration of varying severity. Especially after being parked it is severe. If it was wheel imbalance, I'd say it was up to 100 grams off at its worst. But it sometimes disappears nearly completely after a few kms. - No sounds. - No change in vibration when braking or gently applying park break while driving. (So I suspect not brake related) - No change in vibration when cornering at speed. (So I suspect no wheel bearing or rear differential issues) - Shocks seem to behave normally over bumps, so they are not really suspect. I used to be a mechanic 20 years ago, and by the feel I could have sworn this was a wheel balance issue. But having the problem persist even through swapping out the tires makes me rule out this possibility, and now Im at a loss.
