Dealer Service Instructions for:

Safety Recall V15 / NHTSA 19V-143 Ball Joint

 

Remedy Available

2018 (RU) Chrysler Pacifica

NOTE:  This recall applies only to the above vehicles.  Some vehicles may have been identified as not involved in this recall and therefore have been excluded from this recall.

IMPORTANT:  Some of the involved vehicles may be in dealer new vehicle inventory.  Federal law requires you to complete this recall service on these vehicles before retail delivery.  Dealers should also consider this requirement to apply to used vehicle inventory and should perform this recall on vehicles in for service.  Involved vehicles can be determined by using the VIP inquiry process.

 

Subject

The right front lower control arm knuckle pinch bolt on about 47,780 of the above vehicles may experience a loss of clamp load at the right front lower control arm ball joint, potentially resulting in the right front lower control arm ball joint separating from the steering knuckle.  A separation of the right front lower control arm from the steering knuckle may allow the knuckle to rotate while driving resulting in a loss of directional control, which may increase the risk of a crash without prior warning.

 

Repair

Inspect the right front lower ball joint stud for proper installation into the steering knuckle. If properly installed, replace the pinch bolt with a larger-diameter pinch bolt. If the ball joint stud was NOT properly installed into the steering knuckle, replace the lower control arm, steering knuckle and install the larger-diameter pinch bolt.

 

Alternate Transportation

Dealers should attempt to minimize customer inconvenience by placing the owner in a loaner vehicle if the vehicle must be held overnight.
