Wheel and Tire - Dual Rear Wheel (DRW): Installation

WARNING: This page is about a different car, the 2006 Ford Pickup, 2006 Ford F550 Super Duty, 2006 Ford F450 Super Duty, and 2006 Ford Cab & Chassis. However, it is still accessible from the selected car via links, so may be relevant.

CAUTION: It is imperative that the stamped indents located on the tire bead portion of the wheels are placed as close to 180 degrees from each other while still allowing access to the valve stem on the inside wheel. Failure to correctly install the wheel and tire assemblies can result in a vibration condition.

CAUTION: Do not apply motor oil to the wheel nut threads or the wheel stud threads.

Install the inner and outer wheel and tire assemblies.
1. Position the inner wheel and tire assembly onto the axle.
2. Note the location of the alignment mark.
3. Position the outer wheel and tire assembly.
4. Position the alignment mark on the outer wheel and tire assembly as close to 180 degrees away from the alignment mark on the inner wheel and tire assembly as possible.
5. The valve stem on the inner wheel and tire assembly must be aligned with one of the hand holes in the outer wheel and tire assembly.
6. Install the wheel nuts loosely.
  - On all 2-piece flat wheel nuts, apply 1 drop of motor oil between the flat washer and the nut. If corrosion exists, or the integral 2-piece swiveling wheel nut does not rotate freely, install new swiveling wheel nuts as necessary.

CAUTION: Failure to tighten the wheel nuts in the sequence shown can result in high wheel and tire runout, which will speed up the development of brake roughness, shudder and vibration.

CAUTION: Torque specifications are for nut and bolt threads that are free of dirt and rust. Use only Ford recommended replacement fasteners.

With the weight of the vehicle on the tires, tighten the wheel nuts to 224 Nm (165 lb-ft) in the sequence shown.
If removed, install the wheel cover.
Advise the customer that the wheel nuts need to be retightened at 160 km (100 miles) and then again at 800 km (500 miles) after wheel change or any other time the wheel nuts have been loosened. This is required to permit the wheel clamping system to seat correctly so that the wheel nuts will hold a uniform clamp load and remain fully tightened.
