Hello, I had most of my front suspension overhauled, and a while later new drive shafts both sides. all was peachy until an increasing vibration noise started to come through the foot wells. Having a look at the front with both wheels up; the right hand wheel turns smoothly, but the left side goes tight like it's under pressure, then with a clunk, pushes the engine inwards. Thought it might be a diff bearing going, but one mechanic looked at it and couldn't find anything wrong with the box. I've replaced the left drive shaft, track rod end, gearbox mount and two new tyres - no luck. Does anyone have ANY idea what on earth would make a shaft go in and out like that ?!!!
