Half Shaft Bearing Cage may Break

If the halfshaft bearing cage breaks, the halfshaft may not be able to transmit engine power, causing a loss of drive or it can allow the vehicle to move while in the “Park” position. Either condition may increase the risk of a crash.



Chrysler (FCA US LLC) is recalling certain 2018 Jeep Cherokee all-wheel-drive vehicles. The bearing cage for the right front halfshaft assembly may not have been properly heat treated, possibly resulting in the bearing cage breaking and a potential halfshaft assembly failure.



Chrysler will notify owners, and dealers will replace the front right halfshaft assemblies, free of charge. The recall began September 20, 2018. Owners may contact Chrysler customer service at 1-800-853-1403. Chrysler’s number for this recall is U78.



Owners may also contact the National Highway Traffic Safety Administration Vehicle Safety Hotline at 1-888-327-4236 (TTY 1-800-424-9153), or go to

Safety Recall U78 / NHTSA 18V-494
Right Front Halfshaft


Remedy Available  

2018 (KL) Jeep Cherokee


NOTE:  This recall applies only to the above vehicles equipped with all-wheeldrive built from October 30, 2017 through November 03, 2017 (MDH 103013 through 110311).


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.



The right front halfshaft assembly on about 700 of the above vehicles was built with a bearing cage that was improperly heat treated which may result in the bearing cage breaking and a potential halfshaft assembly failure.  A broken halfshaft bearing cage may lead to the loss of ability of the halfshaft assembly to transmit torque through the all-wheel-drive system which results in a loss of motive power if driving or the inability of the vehicle to maintain PARK if stationary. A sudden loss of motive power can cause vehicle crash without prior warning. An inability to maintain PARK may result in unintended vehicle movement which increases the risk of injury to vehicle occupants or bystanders, or can cause vehicle crash without prior warning.



Replace the right front halfshaft assembly on all affected vehicles.

Service Procedure

Replace Right Front Halfshaft


NOTE: Never handle the halfshaft assembly by the inner or outer boots. This can cause damage to the boot, which will allow contaminants to enter the Constant Velocity (CV) joint. 


NOTE: The inner tripod joint is designed with a retention feature that prevents the tripod rollers from coming out of the inner joint housing up to a specific load. If this feature is overcome and the rollers are pulled past the retention feature the joint will lock up and no longer function properly. The entire halfshaft assembly must be replaced if this occurs.


  1. Raise and support the vehicle.
  1. Remove the right front tire and wheel assembly.
  1. Using a suitable punch, lift the two staked areas in the hub nut to avoid damaging the halfshaft (Figure 1).
  1. While a helper applies the brakes to keep the hub from rotating, remove and discard the hub nut from the halfshaft. The original hub nut is not reusable (Figure 1).

Figure 1 – Hub NutFigure 1 – Hub Nut


  1. Remove and save the nine engine belly pan fasteners and remove the belly pan, if equipped (Figure 2).


NOTE: Use care when separating the ball joint stud from the knuckle so the ball joint boot does not get cut. 

Figure 2 – Belly Pan Figure 2 – Belly Pan


  1. Remove and discard the lower ball joint nut (Figure 3).


NOTE:  Hand start the lower ball joint nut to help protect the lower ball joint thread while using the Ball Joint Press.


  1. Using the Ball Joint Press C-4150A separate the ball joint stud from the lower control arm (Figure 3).

Figure 3 – Lower Ball JointFigure 3 – Lower Ball Joint


NOTE: After separating the control arm from the knuckle, do not let it swing rapidly back up. This can tear the ball joint dust boot.


  1. Insert a pry bar in the opening between the control arm front mounting bolt and the front fascia support beam (Figure 4).


NOTE: The halfshaft may stick in the hub bearing during removal. A dead-blow or plastic hammer can be used to tap the halfshaft inward and out of the hub bearing.


  1. Pry down on the control arm until the ball joint stud is clear of the control arm. Position the knuckle assembly to the side until it is clear of the ball joint stud. Slowly release the control arm.
  1. Swing the steering knuckle outward and off the halfshaft end (Figure 4).

  1. Using a pry bar or equivalent tool release the halfshaft from the transaxle and remove the halfshaft from the vehicle (Figure 5).

Figure 5 – Halfshaft (Transaxle End)Figure 5 – Halfshaft (Transaxle End)


  1. Position the NEW halfshaft under the vehicle and over the lower control arm.


NOTE: Lightly apply grease to the splines prior to installation.

NOTE: When installing the right halfshaft on All Wheel Drive (AWD) vehicles with a single speed Power Transfer Unit (PTU) and manual transaxle, use care when installing the halfshaft as the shaft must pass through multiple oil seals.


  1. Install the halfshaft into the transaxle and lightly twist until halfshaft spline slides all the way into the transaxle.


NOTE: If circlip is fully engaged, tripod joint will not be removable from transaxle by hand. 


  1. Swing the steering knuckle outward and engage the halfshaft end into the hub bearing spline.
  1. Push the lower control arm downward until ball joint stud can enter the bottom of the knuckle.
  1. Insert the ball joint stud into the lower control arm.
  1. Install a NEW lower ball joint to control arm nut and tighten to 18 ft. lbs. Plus 175° (25 N•m Plus 175°) (Figure 3).

Figure 6 - Crimp Halfshaft Hub Nut with Special Tool 10287Figure 6 – Crimp Halfshaft Hub Nut with Special Tool 10287


NOTE: Always install a NEW hub nut. The original hub nut is one time use only and must be discarded when removed.


  1. Install a NEW hub nut and while a helper applies the brakes, tighten the nut to 148 ft. lbs. (200 N•m).


NOTE: Do not use air tools on staking tool while staking hub nut. 


  1. Using the Tool, Front Hub Staking 10287, align the leading cutting edge of Tool, Front Hub Staking 10287 with the top left side channel on axle as shown. Tighten fastener on Tool, Front Hub Staking 10287 with hand tools until the threads bottom out completely (Figure 6).


NOTE:  The hub nut must be staked so that it looks similar to Figure 6. Both edges must be split and bent into the shape shown (Figure 6). The staking must be opposite of the direction to tighten the nut. 


  1. If equipped, install the engine belly pan and tighten the fasteners securely (Figure 2).
  1. Install the tire and wheel assembly and tighten the lugs to 96 ft. lbs. (130 N•m).
  1. Return the vehicle to the customer.
