Hello all got no answer from the axle etc forum. 97 f150 4x4 ext cab. here is my problem with all the snow recently the roads here are quite uneven and rough.Since then my truck has developed a clunking noise not all the time but seems when the truck is moving on an uneven surface. On clear pavement it does not seem to happen yet. very irregular pattern. I have not noticed any vibration at highway speeds. Could this be u-joints? I crawled under the truck with it parked in gear and tried to move the driveshaft and there seems to be a small amount of play in it. Am I going in the right direction? also I had someone in the rear seat and when the clunk happened he said he could feel it under his feet that would put it about right for the front u joint I think? sorry for the long post. any help would be appreciated.
thanks for the reply million but it doesnt seem like that kind of a problem. it only happens when the truck goes uneven for lack of a better word its real hard to explain. Say if your front end is going up a hill and the rear is going down like a driveway or when the front leans to the right while the rear is to the left. Hope that explains a little better
