Installation

1. NOTE: The vertical fasteners for each front axle bearing bracket must be installed with bolt heads adjacent to the engine oil pan to maintain required clearance. Horizontal fasteners must be installed with the bolt heads on the inside surface of the front axle bearing brackets.

   Position the front axle bearing bracket to the front crossmember (5019) and loosely assemble the bolts, retainer assembly and nuts. Do not tighten at this time.

2. To make sure positioning of the front axle bearing brackets is correct, tighten the horizontal fasteners in the side of the front crossmember to 88-118 Nm (65-87 lb-ft). Tighten the vertical fasteners in the top of the front crossmember to 88-118 Nm (65-87 lb-ft).

3. Position the axles in the front axle bearing bracket. Install the pivot bolt and tighten nut to 115-163 Nm (85-120 lb-ft).

4. Remove the blocks under the engine and lower the engine into position. Tighten the bolts to specification listed in the appropriate engine section in Group 03.
