 The car we were working on...  The car we were working on had knock-off wheels. We removed the wheels and also removed the hubs because we needed to loosen the emergency-brake shoes. If the rotor will come off without loosening the emergency brake, hub removal isnt necessary. This decreases the chance of excessive runout once the assembly is reinstalled. |

 Once the calipers are removed,...  Once the calipers are removed, he wraps some tape around them to keep the retainers in place. There is no need to loosen the brake lines; just put the caliper up out of the way. |
 Our rotor was removed previously....  Our rotor was removed previously. (Note the rivets are already removed.) Luckily, they installed the rotor properly so we could get to the adjuster for the emergency brakes. |

 The main reason this job is...  The main reason this job is farmed out is not having the tools to do the job properly, and theyre available through the major advertisers in Corvette Fever. Having the proper tools means you can always do the job again later. This tool... |

 The new ones are tapped back...  The new ones are tapped back in place with a special tool that wont damage the surface of the bearing race. |
 This tool allows you to check...  This tool allows you to check the bearing preload without having to press the bearings onto the spindle. The process is much easier with this tool if you need to change the spacer. |
 Chris has many spacers and...  Chris has many spacers and uses dial calipers to choose the proper one. He can feel the proper preload because of his many years working on Corvettes. |

 Make sure when you install...  Make sure when you install the knock-off wheels that the lugs dont go through the holes for the pins. Chris has seen several sets that were installed improperly. Take a little time to make sure its right. |
Brake-rotor runout is a major concern on mid-year Corvettes, and owners often simply remove the trailing arms and have them rebuilt, having new bushings and rotors installed at the same time. Purchasing the necessary tools can be another reason for not attempting this task. Youll need a spindle-removal press, a spindle-bearing puller, a spindle bearing setup tool, and a rear-spindle installation tool. Total cost: about $500. While we were at the Corvette Clinic, Chris Petris showed us that you can change the rear bearings without removing the trailing arms, with the right tools. Follow along as we show you how.
Once youve installed a new set of rear wheel bearings, and if you purchased the required tools, you have a pretty well-equipped toolbox. You know what they say: Give a man a fish and you feed him for a day; give him a fishing pole and youre supporting an addiction. Such it is with Corvetting!
