I'm sure this has happened to others--a 1993 Jeep Cherokee 5 speed with standard tires/wheels--while crossing bridge expansion joints or moderate broken pavement at 50mph or faster, the rear axle starts jumping up and down uncontrollably. The only way to stop it is to slow down below 35 mph. It feels like it starts in the right rear wheel, then quickly involves the whole axle. No visible spring damage, tires in good shape (and this happens at various tire pressures), new shock absorbers (a fix that didn't work). Got any ideas?
