What can fail
The frame can crack where the steering gear attaches, and the steering gear mounting bolts can break. This affects certain 4x2 pickup trucks with V6 engines or Shelby packages built between October 1988 and June 1990.
What the fix does
Dealers will add frame reinforcements and replace the steering gear mounting bolts. If the frame is already cracked, weld nuts will also be replaced.
