What is wrong
THE SPRING SEAT PLATE, LOCATED BETWEEN THE AXLE HOUSING AND THE SUSPENSION SPRINGS, MAY DEFORM DUE TO SPRING BENDING. AS A RESULT, THE CLAMPING FORCE IN THE ASSEMBLY MAY BE REDUCED. LOSS OF CLAMPING FORCE COULD CAUSE SPRING FAILURE AND THE AXLE WILL DISLOCATE. ALSO, THE TIRE COULD COME INTO CONTACT WITH THE SPRING.
The fix
Recall repairs are free of charge.
THE DEALER WILL REPLACE THE EXISTING SPRING SEAT WITH A NEWLY FABRICATED SEAT WHICH IS WELDED TO THE HOUSING. AN IMPROVED SPRING CLAMPING PLATE AND NEW SPRINGS WILL ALSO BE INSTALLED WITHOUT CHARGE.

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.
