Rear end shaking at 50mph

[agrich2]

I have a 99 Ranger 3.0L X-cab. It has 188K on it. 8.8 rear end.
Ever since I can remember, the rear end shakes at 50-60mph.
I have replaced tires, drums, brakes, rims, axle bearings....
I have not gone through the rear differential, or drive line.
Has anyone else had similar issues????

Thanks,
Aden Rich

Check the drive shaft. it might be bent or out of balance. that would transfer to the rear end.

It could be a rear axle shaft is bent slightly. I've seen it a number of times while I was working in a body shop. Should be pretty easy to check with a dial indicator.

loose nut that holds the leaf-pack together....loose nut(s) that hold the u-bolts tight....loose nut that holds the pinion shaft on the yoke....plus what they said
