This PI is being updated to add models. Please discard PIT3026A.
The following diagnosis might be helpful if the vehicle exhibits the symptom(s) described in this PI.
Condition/Concern:
Tire scrub noise or crow hopping during low speed turns(parking lot maneuvers). It has been found that the steering rod (center link) can be installed backwards. There is a potential for this to occur on all trucks and utilities with recirculating ball
type steering that does not use a steering dampener.
Recommendation/Instructions:
To qualify the correct installation of the steering rod, compare to a like vehicle. In a correct installation the steering rod should curve to the rear, outboard of idler/pitman attachment holes and inboard of the inner tie rods.
The idler and pitman attaching holes are only tapered in one direction. So that with the steering rod installed incorrectly the curved portion of the rod between the idler/pitman holes and inner tie rods would be curved toward the front of the vehicle.
Remove and correctly reinstall the steering rod (center link).
Please follow this diagnostic or repair process thoroughly and complete each step. If the condition exhibited is resolved without completing every step, the remaining steps do not need to be performed.
