Question about 1988 Ford F 150
It could be a spark plug, plug wire, or a coil. Sometimes thay break down intermittently. If it needs a tuneup, that would be the first thing to do.

I would take the truck to an autoparts store and have the fault codes retrieved from the computer. Most stores will do the scan for free. I would lean toward a faulty throttle position sensor, but that's just speculation. The fault codes should narrow the problem down. Hope this helped and best wishes.

When you say "throughout" that would indicate that it is coming from the rear of the truck..
There could be a number things causing this..
It could be a bad tire or a broken belt on a tire..
A test for this is - roll along at 3 miles per hour.. If you feel a wobble - that is probably a broken belt in a tire..
Or maybe even a bent axle..
It could be a bad universal in the drive shaft..
It could be a broken shock/strut or mount or both..
Best of luck !

Check your TPS Throttle positioning sensor. Sounds like it has a dead spot in it or it is failing. May also be a wiring harness issue or loose connection at TPS too! If its intermittent then it will soon go out completely. It should be located on your fuel pedal. Remove it and check it with an ohm meter. Check resistance all the way thru from 0-100 percent. When it is not working it should do nothing and show no resistance. When it is working the resistance value will increase and or decrease as you turn the sensor.

Ring and pinion noise for sure,yes. Check for play right at the yoke where the drive shaft goes in.
I've seen a few fords where the pinion nut was loose and after re torquing they lasted another 100,000
