Default New, really f-ing annoying vibration. F250

1996 F250 5-sp 2WD diesel

This week, I squirted up to about 80 mph on the interstate. Truck has always run good that fast, however, I started to get a vibration like I was going over a rippled surface.

I slowed down, changed lanes and the new vibes stayed with me. Makes a real loud, low-frequency droning that is really tiring to drive with at all speeds above 55 mph.

So far:
1. Had tires re-balanced (no improvement)
2. Checked for bad ujoints and midship bearing under the truck - LOOKS okay, but IDK if looking is enough.


Any idears?

belt let go on a tire was my first thought

can you feel the vibe more in the steering, or the whole truck (can you tell if it is front or rear)

Do you rotate the rear tires to the front, and front to rear?

jack it up and check wheel bearings?

Sell it

My dually had a same drone vib from 65mph on. I replaced the "mid ship" bearing and all joint's and it went away. Yeah there is really no good way to check the ujoint's unless you physically take them apart. The trunyon usually starts to get an indentation from the needle bearings. Causing the vibe, may not be in your case but it is a start with it being this cold. The salt and lack of lube does wonders this time of year.

I'm with Killer B. This midship bearing is probably going. Your truck does have a two piece driveshaft right Scooter?

After 4 hours of struggling with three fucking u-joints and a center bearing frozen to the rear d/s, my truck is vibration-free.



-and my hands are beat all to hell. Thankfully I had a balljoint press and an impact wrench for the u-joints. Stupid center bearing needed part of my bearing press and a BFH.
