Refer to illustration under Spring, Coil, F-150 and Bronco, in the Removal and Installation portion of this section.
Removal
Raise vehicle on a hoist. Place a tall jack under the axle arm near the front axle bearing bracket (3K090) and slowly raise the vehicle so axle is supported by the jack.
Remove the axle-to-bracket retainer bolt and nut.
If necessary, pry the axle out of the front axle bearing bracket. Raise the hoist slowly to disengage the axle from the front axle bearing bracket.
If necessary, raise the engine to provide access to the vertical fasteners in the top of the front crossmember (5019). Refer to the appropriate engine section in Group 03.
Remove and discard all bearing bracket-to-crossmember fasteners. Remove the front axle bearing bracket.
Installation
NOTE: The two rearward vertical fasteners must be installed with bolt heads adjacent to the engine oil pan to maintain required clearance. The bolt and retainer assembly must be installed with bolt heads on the inside of the bearing bracket surface.
Position the front axle bearing bracket to the front crossmember. Loosely assemble the bolts, retainer assembly and nuts. Do not tighten at this time.
To ensure correct positioning of the front axle bearing bracket, tighten in two stages.
Lower the hoist until the axle engages the front axle bearing bracket. Install the bolt and nut. Tighten to 213-288 Nm (157-211 lb-ft).
Remove the jack and lower the vehicle.
