1989 Ford Ranger Shudders

I have a 1989 Ford Ranger XLT,standard transmission, with 215,000 miies on it. Lately, the whole thing shudders from 22-33mph. This happens on accellerating, decellerating, clutch in, or clutch out, 2nd gear or 3rd gear.

I’ve gotten two suggestions: throw-out bearing or driveshaft

Any other ideas? Thanks!

Check the drive shaft U-joints for wear.

Raise the rear of the vehicle so both tires are off the ground. With the transmission in neutral and parking brake off, rotate one of the rear tires back and forth while observing the U-joints. If a U-joint is worn is will be evident.
