My car has a vibration on the left drive shaft. This vibration happens when accelerating either at low or high speeds. The vibration is always there, the moment I stop accelerating, the vibration stops and runs smoothly, when I start accelerating I can I feel the vibration. I have tried to change the inner CV joint, outer CV joint, the drive shaft and today I went as far has change the differ in the gearbox, despite doing all this I still have the vibration. Please note that this problem started last year after I replaced the gearbox. Please help, how can I fix this problem?

If you have already replaced the inner and outer CV joints, the drive shaft, and the differential in the gearbox

Hi Ken, thanks for your response. Sorry I did not mention this in my first post. The wheel bearing was replaced, the suspension was replaced and axle was replaced, despite this, the problem did not go away.

I would rotate the tires front to back, I have seen a tire come apart internally and it will cause this kind of problem.
