Truck hard shake at 25-30 mph

Hey all I have a regular cab 1993 5speed 2x4

In any gear accelerating between that speed the front of the truck jerks up and down violently. Only time it doesn't do it when I push in the clutch or stop accelerating.


If need be I will make a YouTube vid

Check your u-joints, and carrier bearing if you have a 2 piece shaft.

Second that motion.

U-joints are staked in on these models, they are replaceable, but are more time consuming and annoying lol. I have to tackle that job sometime soon.

Check for a tread separation or maybe one of your tires coming apart. You might have hit a curb and broken the tire internally.

added edit;
you could have picked up a nail which allowed water into the tire, which would have allowed a steel belt (if any) to rust, causing tread to bubble. That one happened to me.
