94 crew C3500 automatic flatbed.
I can feel vib starting at 40 and gets worse to 65. Afraid to go faster than this as one time i did, ujoint popped out. No noticeable up and down or left and right shake in steering wheel.
Replaced:
1.R/h axle seal and brake pads (dont think this had much to do with issue, but first thing i did when i bought truck due to oil coming out from drum)
2. Ujoints
3. Center driveshaft bearing
4. 4 new tires installed and balanced on rear.
Front tires good, balanced.
Driveshafts balanced together.
Ideas?
