Question about 1994 Jeep Grand Cherokee
FRONT TIRE AND AXLE BOUNCE AT 40-50 MPH AFTER HITTING BUMPS. MUST SLOW DOWN TO CORRECT IT. REPLACED SHOCKS, BALANCED TIRES, REPLACED STEERING BOX, REPLACED BUSHINGS. INSPECTED ENTIRE FRONT END, ect.
Relace your shocks. the design of any dampner(strut or shock design) is to return the wheel to the road for handling and safety. when the shock is worn out is with continue to bounce like a basketball. it has no more strength to return to wheel to the road. a common misconception is that they are there to absorb, not true. the springs or torsion bars are there to absorb and create ride height. the shock does nothing more then return the wheel to the road. simple and inexpensive.

2 Possible issues: When the tires hit a bump, it causes them to lose the "drag" that they need to be in position & if the alignment is off more than just a little, you will get a hopping tire as it attempts to regain it posture. Slowing down allows the drag from the brakes to help get it back in line.
I've seen tires with water do a similar thing which makes sense since when the water gets disturbed inside of them, it would cause the "balanced" tire to be out of balance. I specifically had a mechanic in my early years, '74 attempt to balance a tire using the type of balancer that dealerships used that was pushed up against the tire mounted on the vehicle, it rotated the tire & the mechanic adjusted the little balancers mounted on the wheel to determine the location & need for weight. "OLD but it worked. He couldn't get my tire to balance & it would start bouncing during the test-off & on. I later discovered by replacing the tire that it had a few cups of water in it & by the rust of the wheel, it had been there for a while. After that, I've checked & found water more than once & it has cured many a bounce & imbalance situation. Good Luck
