The hub caps must be removed before raising the vehicle off the ground.
Use extreme caution when removing the front and rear wheel covers. Damage can occur to the center cap and/or the wheel if screwdriver type tools are used. A pulling motion, not a pry off motion, is recommended to remove the caps.
For 2500/3500 Single Rear Wheel (SRW) models, use the flat end of the lug wrench to hook and pull off the hub cap. Find the opening in the hub cap, insert the lug wrench, and pull off the cap. If you need to pry against the wheel, protect the wheel surface.
On 3500 models with Dual Rear Wheels (DRW), you must first remove the hub caps—use the procedure noted for the single rear wheel. For the wheel covers (wheel skins), insert the flat end of the lug wrench between the outer edge of the wheel cover and the wheel. Pry against the wheel to remove the wheel cover. Repeat this procedure around the wheel until the cover pops off.
Use a pulling motion to remove the hub cap. Do not use a twisting motion when removing the hub cap, damage to the hub cap; finish may occur.
The rear hub caps on the dual rear wheel has two pull off notches. Make sure that the hook of the jack handle driver is located squarely in the cap notch before attempting to pull off.
Replace the wheel covers using a rubber mallet to ease the installation. Align the wheel cover vent holes to the wheel vent holes. Tap on the wheel cover as needed to firmly seat it evenly around the wheel.
