Attention:
Complete wheel changing instructions for each vehicle line can be found under Tire and Wheel Removal and Installation in Service Information (SI).
This bulletin is intended to quickly review and reinforce simple but vital procedures to reduce the possibility of achieving low torque during wheel
installation. Always refer to SI for wheel lug nut torque specifications and complete jacking instructions for safe wheel changing.
Supercede:
This bulletin is being revised to include the 2011 model year and update the available special tool list. Please discard Corporate Bulletin Number

Frequency of Wheel Changes - Marketplace Driven
Just a few years ago, the increasing longevity of tires along with greater resistance to punctures had greatly reduced the number of times wheels were
removed to basically required tire rotation intervals. Today with the booming business in accessory wheels/special application tires (such as winter tires),
consumers are having tire/wheel assemblies removed - replaced - or installed more than ever. With this increased activity, it opens up more of a chance
for error on the part of the technician. This bulletin will review a few of the common concerns and mistakes to make yourself aware of.
Proper Servicing Starts With the Right Tools
The following tools have been made available to assist in proper wheel and tire removal and installation.
-
J 41013 Rotor Resurfacing Kit (or equivalent)
-
J 42450-A Wheel Hub Resurfacing Kit (or equivalent)
Corroded Surfaces
One area of concern is corrosion on the mating surfaces of the wheel to the hub on the vehicle. Excessive corrosion, dirt, rust or debris built up on these
surfaces can mimic a properly tightened wheel in the service stall. Once the vehicle is driven, the debris may loosen, grind up or be washed away from
water splash. This action may result in clearance at the mating surface of the wheel and an under-torqued condition.
Caution
Before installing a wheel, remove any buildup on the wheel mounting surface and brake drum or brake disc mounting surface. Installing wheels with
poor metal-to-metal contact at the mounting surfaces can cause wheel nuts to loosen. This may cause a wheel to come off when the vehicle is moving,
possibly resulting in a loss of control or personal injury.
Whenever you remove the tire/wheel assemblies, you must inspect the mating surfaces. If corrosion is found, you should remove the debris with a die
grinder equipped with a fine sanding pad, wire brush or cleaning disc. Just remove enough material to assure a clean, smooth mating surface.
The J 41013 (or equivalent) can be used to clean the following surfaces:
-
The hub mounting surface
-
The brake rotor mounting surface
-
The wheel mounting surface
Use the J 42450-A (or equivalent) to clean around the base of the studs and the hub.
