CAUTION! Do not hammer the bearing insert into place and don't nick or gouge the bearing faces. DO NOT apply any lubrication at this time.

  • Clean the faces of the bearing inserts in the block and the crankshaft main bearing journals with a clean, lint-free cloth.

  • Check or clean the oil holes in the crankshaft, as any dirt here can go only one way- straight through the new bearings.

  • Once you're certain the crankshaft is clean, carefully lay it in position in the cylinder block.

  • Before the crankshaft can be permanently installed, the main bearing oil clearance must be checked.

  • Cut several strips of the appropriate size of Plastigage. They must be slightly shorter than the width of the main bearing journal.

  • Place one piece on each crankshaft main bearing journal, parallel with the journal axis as shown (see illustration).

  • Clean the faces of the bearing inserts in the main bearing cap assembly. Hold the bearing inserts in place and install the assembly onto the crankshaft and cylinder block. DO NOT disturb the Plastigage. Make sure you install the main bearing caps with the arrows facing the front of the engine, then install the stiffener.

DIFFERENTIAL LUBRICANT CHANGE (every 60,000 miles or 48 months)

Refer to illustration 29.3

  1. This procedure should be performed after the vehicle has been driven, so the lubricant will be warm and therefore will flow out of the differential more easily.

  2. Raise the vehicle and support it securely on jackstands. You'll be draining the lubricant by removing the drain plug, so move a drain pan, rags, newspapers and wrenches under the vehicle.

  3. Remove the fill plug (see illustration 16.2a (rear differential) or 16.2b (front differential)). Now remove the drain plug and allow the lubricant to drain into the pan (see illustration), then clean and reinstall the drain plug. Tighten the plug to the torque listed in this Chapter's Specifications.

  4. Use a hand pump, syringe or squeeze bottle to fill the differential housing with the specified lubricant until it's level with the bottom of the fill-plug hole. If using synthetic axle lubricant, the level should be below the fill-plug opening by 1/2-inch.

    Identical to Haynes Manual
    November 11, 2015
    This manual is fairly comprehensive, detailed and easy to follow. Does not contain everything though. Tried to find information on troubleshooting and repairing a inoperative horn, but found nothing. This manual is practically identical to the Haynes manual. Same pictures, diagrams and text. Looks like it was produced by the same source.

    ABS Components
    February 3, 2015
    I specifically ordered this manual for step by step instructions regarding removing the ABS control and/or ABS pump. The manual was not helpful. It only mentioned that there was one of each but was silent except to send it to the dealer..
