1993 Explorer - ABS Light & left rear wheel locks up

First, you're going to need to know what code(s) are stored in the ABS module.... these may be symptomatic or they may be causal.... There is a very good chance that the wheel is locking up becuase of a leaking wheel seal and the ABS light is coming on because of the repeated lock ups.

At the very least... if you are having brake problems of any sort, the last thing to do is drive the sucker.....
