02 250 bad cross bearings? or something else.
02 f250 auto/4x4 98k miles. about a week ago started hearing chirping under the truck. i assumed the cross bearings/u joints whatever you want to call them, or the support bearing were on their way out on the rear driveshaft.
today jacked the rearend up, tranny in neutral, i spun the tires/driveshaft and couldnt get the sound to occur. there were no visible signs that they were shot that i could see, no play in all 3 joints and no play in the support bearing. I'm thinking maybe they need a load/more speed on them in order for the sound to occur? any help/ideas are appreciated..thanks
