If there’s one thing I hate to find when working on cars, it’s wheel and hub corrosion. Aluminum and steel have this thing where if they touch, they get all corroded.

An example of what I’m talking about. That white and black stuff around the hub and on the back of the wheel is corrosion.

The problem with corrosion is that when you put the wheel back on and tighten the lug nuts, it may not seat correctly, and cause a vibration when driving. I’ve had two customers come back complaining of vibration after I’ve worked on their car, so now every time there’s noticeable corrosion, I’ll clean it off.

Cleaning them isn’t hard, it just takes a die grinder and a dust mask, but it takes several minutes if there’s a lot of corrosion, and time is really money in this business. But when it comes down it, to preventing comebacks, I think it’s worth the extra time to prevent having to do it later without being paid because the customer had a problem.
