Sounds as If You Have A Chipped Tooth On the "RING GEAR" in the Differential (Rear Alex).
Is this Where You Hear The Noise Coming from? If So Remove Diff Cover With One Wheel OFF The Ground Trans In Neutral Rotate Drive Shaft and Look Closely For ANY Abnormal Surface on EACH Tooth of RING GEAR= the Large one And The "PINION GEAR" the Small one. If you find Chip or Rough spot Diff Must Be Rebuilt. Beyond that A Pinion Bearing can Also Make A Knocking Noise But the "GEARS" Will Be a Rhythmic Noise. I Hope this is of Some Help To You Good Luck !!

I have a 1993 Jeep Grand Cherokee Laredo. There is a "violent" vibration that occurs only when you are going 40-60 MPH and you hit a bump or pot hole on the highway. The front end begins to...
Vibration from about 40-60 mph is usually attributed to wheel balancing, but the onset when you hit a bump seems to indicate play in the steering linkages (tie rods etc) or suspension members and stabiliser bar rubbers but you had that all checked out, that brings us back to the wheel balancing.

94 Jeep Grand Cherokee Laredo: No power to left tail light
Traced the problem to the Lamp Outage Module located in the rear left quarter access panel behind the spare tire. Arcing had occurred on the left taillight line. Fortunately this part is readily available at your local Jeep recovery yard (none available in the U.S. from dealers). Recommend J& W Auto Wreckers in Antelope, CA (web site available). Massive number of Jeeps and fair prices. If you don't want to replace the LOM then you can join the two connectors that go into the LOM (LOM is optional) but you'll always show a lamp failure on your console.

1993 JEEP GRAND CHEROKEE LAREDO IM TOTALLY BAFFLED
Back up a minute...Do you have spark from the coil wire? (juice from coil) If so, change or check rotor and cap (wires do not all go bad at same time so unless they are wet, likely at least good enough to start engine)

Knocking sound that intensifies when drivng faster
It could be a drive shaft. You may need to go under the vehicle and see if there's any play at the joints that are on the ends of the shaft.
