Just bought this 1994 Laredo this past Sunday - immaculate from original owner with 96m miles. Monday after making a sharp U turn, the right rear wheel pulses and locks up, and slowly loosens when going straight for a while. So far, my mechanic cant figure it out. He also says it feels like the left (I dont feel it) locks on right turns. The whole thing feels funny. Suggestion anyone!?:confused:

If it has drum brakes on the rear, check the rear shoes for excessive wear and the wheel cylinders, one of the rear brake cylinders could have a leak which is not allowing rapid pressure release of the cylinder(in other words, it could be sticking) Hope this helps.

Sounds like it needs limited slip lube in the rear end.
