    Im getting a vibration at around 55+ mph an I think its
    from the rear. I've replaced all the front end except
    the hubs those will be soon. Just wondering what
    joints to put in the rear. I've heard alot of spiced put don't
    know what I need for size an if I should go with grease or not
    ill be doing all the work my self. Any ideas or part number
    an site I can look at buy from would be helpful.
    First time doing rears on any of my trucks. I never kept
    them past 100k .this one is my work truck/ that I tow/plow
    With.I put on about 110k in the last 1.5 yrs.an just replaced the whole front
    at 100k miles

    Be prepared for the worst. I thought it was my ujoints or my driveshaft bearing making the truck shake. Ends up my clutches are frozen in the rear diff. 1500 to overhaul and rebuild. Last night we changed the fluid(synthetic) and added the ford additive hoping in 75-100 miles it frees up the clutches. I'm away this weekend so I'm hoping by the end of the week I can put 100 miles on the truck( no snow ). I have an 03 f350 srw crew short bed 103k mi hauls and plows.

    At 55mph I would suspect the drive shaft. Could also be a belt shifting on a tire or a wheel weight shifted from deep snow.

    As for the rear end clutches... This normally only shows issues during the first few feet of take off causing a shuttering sensation from the rear end. Normally this can be rectified with fresh fluid and make sure you put in synthetic back in. From what I can understand this is caused by dirty fluid making the clutches to grab in-properly.

    Weird cuz fluid was never changed and came out perfect. No metal shavings at all! Yes synthetic plus additive added. If it doesn't go away. Tires have 35k on them. A little dry rot 3 yrs old so maybe time for new tires. What sux is they have 50% tred left. The clutches looked hung up like they were stuck making the wheels posi while on jack stands

    Not hard to find a bad u-joint . Just drive the truck a mile or so shut it off crawl under it , lick your fingertip and touch both u-joints . The hot one is the bad one ! Or if you don't wet your finger first , it'll be the one that caused the blister on your finger ! Thumbs Up

    half left an I had them balanced an rotated about 5k miles ago.
    I think ill still replace them an the boot an see how it feels
