I have a 94 F150 4+4 pickup, extended cab, 5.0 engine, auto matic with overdrive. 163000 miles in good condition. My problem is that when driving I hit 45 the truck starts to vibrate loudly and continues to do so till I let up on the gas. It will not do it when maintaining speed only when the gas is accelerated. I have replaced the universal joints and have checked out the front end and found nothing wrong. I cant see anything wrong with the driveshaft it looks in good condition. What could it be? And is it safe to drive like this?
have the same problem?
