Front Hub Staking


Service Procedure

A. 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).

  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.

Belly PanFigure 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).

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).

Lower Control ArmFigure 4 – Lower Control Arm


  1. Remove three bolts holding the support bearing to the engine bracket (Figure 5).
  1. Separate the support bearing bracket from the engine support bracket and support the halfshaft on a suitable stand.
  1. Using a pry bar or equivalent tool release the halfshaft from the transaxle and remove the halfshaft from the vehicle.

Support Bearing BoltsFigure 5 – Support Bearing Bolts


  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. Position the intermediate bearing bracket onto the engine support bracket and align the bolt holes.
  1. Install the three bolts to hold intermediate support bearing to the engine bracket and tighten the bolts to 17 ft. lbs. (24 N•m).
  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).

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.
