What is wrong
THESE VEHICLES HAVE FRONT AXLES WITH BRAKE CAM OPERATION OPPOSITE TO THE ROTATION OF THE BRAKE DRUM (CAM OPPOSITE), AND THERE IS A TENDENCY FOR BRAKES TO CHATTER UNDER LOW AIR PRESSURE, RESULTING IN VIBRATIONS. THE VIBRATIONS INDUCE STRESSES IN THE TIE ROD END BEYOND ITS ENDURANCE LIMIT, AND RESULT IN CRACKS IN THE THREADED PORTION OF THE STUD WHERE THE TUBE ENDS.
What can happen
CRACKS IN THE TIE ROD CAN RESULT IN SEPARATION OF THETIE ROD AND LOSS OF VEHICLE CONTROL WITHOUT PRIOR WARNING.
The fix
Recall repairs are free of charge.
REPLACE THE CAM OPPOSITE BRAKE ACTUATION WITH CAM SAME BRAKE OPERATION, BY INTERCHANGING THE LEFT AND RIGHT CAM ASSEMBLIES TO AVOID BRAKE CHATTERING; AND REPLACE TIE RODS.

A recall means the maker found a safety problem and offers a free fix; it does not mean every unit has the problem. Units affected are as reported by the company. Popular models sell more and so have more recalls and complaints. Official public data; texts are shortened. A dealer can tell whether a single vehicle still needs the repair.
