Rear end shake
Hey, new guy here. I don't have a Ranger or B-Series, but I do have Ford's older B-Series counterpart. 1979 Ford Courier, 2.3L/5-spd. I have had a bad rear end shake since I bought the truck nearly three years ago, so I'm sure it existed well before then. It only happens around 60-65 mph, and there is also a kind of buzzing/humming sound whenever I'm coasting to a stop in neutral. I have:
- Replaced and balanced the tires several times
- Rotated the tires several times
- Replaced all four wheel bearings
- Replaced steering linkage
- Replaced front suspension
- Balanced driveshaft twice
- Replaced driveshaft center bearing
- Replaced all three U-joints
- Checked rear wheel lateral and radial runout
- Had the front end aligned three or four times
- Checked engine and trans. mounts

As in are they phased? I'm sure they are, because I got the truck up on stands and had my wife run it at 60, and the driveshaft wasn't vibrating or buzzing or anything like that. I forgot to mention that when I was doing this the driver's side rear wheel was vibrating rather loudly, and the vibration was definitely visible. The other wheel wasn't vibrating at all. I also seem to remember checking the pinion for play but getting none.
