I have had a new vibration in my well miled 123,000 and well cared for F250 with manual hubs on 4x4. I thought it was the Firestone tires I put on it a year back that showed severe tread surface chipping SO I bought new Michelins truck still has a loud and visable vibration in mirror It starts at about 53 mph and goes till 70 then quiets down smooths out I had recenty work done on rear drums (turned) and front axle u joints, and ball joints replaced. I hate to keep quessing what is wrong I could buy new drums to take that out of equation for not to much money I have looked at 4x4 while truck is creeping and no movement of axle shaft so hubs are disengaging. online threads seem to suggest that this may be a motor mount trans mount balance problem. I have not checked mount as of yet. Any input will help thanks ---

Additionally I have taken car to 68ish and put in Neutral and vibration still exist till falls below 55ish so not to sure of the mount suggestion I found online I love this truck od more over dont want to get a new truck payment anytime soon with this truck being in the $35000 plus class today ---

When you replaced the tyres did you have the new ones balanced? When was the last time it was aligned, was it done after the balljoints? You have covered a lot of good guesses. Has anyone check the engine mounts? ---

I have not yet checked motor mounts but will, yes tires where balanced both times and after first set of tires it was aliened but not the new ones as I only had 7K on old aleign, but still a good idea to have checked. The 97 expedition had a very similar issue that has a lot of threads online about it. This never was an issue till first new tires and other repairs where done most invasive being the ball joints. I am going to put a dial indicator along each rim and spin and see if all running true maybe I bent a rim but the tire guy should have picked up on that this last time around you would think … forget I said that… hey I got an idea I’ll strap myself under truck have friend take to problem speed and use a stephiscope and listen for the problem area in a McGiver like fashion ya right and be on the next jackass installment of stupid human tricks… what of the shocks I haven’t checked for a bad shock yet. Also you can really feel this vibration in the transfer case shifter and slightly in steering wheel ---

Ok I have gone wheel to wheel and have discovered the possible culprit MY rear ujiont is badly worn and I should have know better than to check it without lifting the truck. On ground it seemed solid and looked like they were fine. When I put one tire up and gave the wheel a push back and forth O the play in that joint! that will make a drive line vibrate for sure. this is a leason an a friends father had told me years ago never trust the grab the driveshaft and wiggle test. I am living that rule now. It had more backlash than a misspoken Presidential canidate!@#!! Or for that matter our current Lord of the manor President Shrub I mean Bush LOL tommorrow I shall attempt to wrestle these ujoints out and post back ---

If the u-joint is not the culprit, check the front suspension. You might have a worn component. And our esteemed presidential candidates do _not_ misspeak - they are misquoted! ;^)
