Pickup Box Lean

1. Place vehicle on a flat, smooth surface.

2. Inspect vehicle for any heavy add-ons that may cause excessive weight on any corner of vehicle.

3. Vehicle should be empty, fuel tanks should be full, without cargo in the pickup box (such as tools, equipment or debris).

4. Vehicle must be sitting on the wheels and tires and not on a hoist, jack, or jack stands.

5. Check all wheels and tires.

   1. Wheels must be same size and design, right and left side on each axle.
   2. Tires must be same brand, tire size, tread design, and equal tread wear side-to-side on each axle.
   3. Wheel size and design, tire size, and tire design should be indicated on the Vehicle Certification Label. Use of larger size, off-road, wide tread wheels and/or tires are not approved.
   4. Check tire pressures of all tires; inflate to specifications indicated on the Vehicle Certification Label.

6. Lay a straightedge at least 2 meters (6-1/2 feet) long across the rear edge of the pickup box and have an assistant hold the straightedge.

   
   
   
   
   

7. Stand 1.9-2.4 meters (6-8 feet) behind the truck. With your eye level at the top of the pickup box, have your assistant lift whichever side of the straightedge is necessary to make it parallel to the back window of the cab.

   
   
   
   
   

8. Measure distance between bottom of straightedge and top of pickup box outer panel. If distance exceeds 6.5mm (.25 inch), shim the low side of vehicle as follows:

   1. If distance is between 6.6mm and 18mm (.26 inch and .70 inch), shim the axle. Refer to Shimming, Axle in the Adjustments portion of this section.
   2. If distance is between 18mm and 30mm (.70 inch and 1.20 inch), shim the pickup box. Refer to Shimming, Pickup Box in the Adjustments portion of this section.
   3. If distance exceeds 30mm (1.20 inch), shim both the axle and pickup box. Refer to Shimming, Axle and Shimming, Pickup Box in the Adjustments portion of this section.

9. If, after shimming, the rear bumper is not aligned with the rear of pickup box, realign the bumper as follows:

   1. Remove the four bumper-to-chassis frame attaching bolts.
   2. Ream the four holes (two on each side) to 17mm (.66 inch) on the bumper arms through which the chassis frame attaching bolts are installed.
   3. Reinstall the bumper to chassis frame with attaching bolts and align the bumper to the pickup box.
   4. Tighten the bumper attaching bolts to 95-140 Nm (70-103 lb-ft).
