Got the van checked up, front brake rotors and brake pads changed, faulty wheel changed, suspension got checked, wheel balancing done still the van vibrates once reaches the speed of 50-55 mph. The van vibrates as a whole and not just the steering. Not able to understand the reason. Please help.

If you feel the vibration in the seat and floor, chances are the problem is in the rear. Have you checked everything in the rear?

Thanks for the reply. I just changed the rear left faulty wheel and Don't know what mechanics checked on the rear. Can you please suggest what nereds to be checked in the rear so that I can ask specifically to mechanic. Its true that seats and floor vibrate. Highly appreciate your help.

Check for a bent rim, check rear alignment, check bushings, check rear wheel bearings.

Hi, my mechanic checked the rear things you suggested, but found them ok. Could round tires or abnormal wear n tear be the Problem?

Abnormal tire wear can cause it.

I got the tires checked and mechanic told that there are dimples in all four tires and that is causing Vibration. He asked to change all Of them. Is IT true and guarantees that IT would resolve IT? Also He suggested to replace Front left tie end rod. Can movement in that cause Vibration too? Have gone puzzled, please guide.

If the tires have shifted belts, that could cause a vibration. Please remember, I am not there to see what is going on.

As far as the tie rod, it is doubtful that is causing the vibration. It will cause play in the steering and should be replaced if bad.
