The tie rod used on the dana fa-64 front drive axle has a threaded sleeve to permit toe-in adjustment without removing an end. The tie rod bar is necked down to incorporate the sleeve. A stress riser is created at the threaded portion of the adjustment sleeve which may cause a fatigue fracture and failure of the tie rod where it screws into the sleeve.
Replace the tie rod with a tie rod that does not use an adjustment sleeve.
