Vibrations can sometimes be a real PITA and after a lot of testing and checking, I have to say I'm stumped on the source of my vibration.
So the problem is that I get a vibration at approximately 40km/h under the following conditions
1. The car must be accelerating for the vibration to occur, i.e does not vibrate when braking or cruising (although maintaining the 40km/h does produce a VERY slight vibration, thought he actual vibration is much worse).
2. Warm or cold engine, the vibration is there
3. Above 45km/h and below 35km/h, the vibration disappears. Even at speeds of 130km/h there is no vibration.
So far what I've checked is;
Engine mounts
CV joints
Wheel bearings
Wheels are balanced and aligned.
One of the rims is slightly bent, though I would have thought that this sort of vibration would get worse with increasing speeds. My winter set is in the storage and is a hassle to take out, so I won't be able to test this for a while.
Any other suggestions in the mean time? Is it highly probable that it's the slightly bent rim causing the issue?
Thanks in advanced, been killing me for a while
