Here’s what you should know as a technician when servicing tapered wheel bearings.
As technicians, you may have noticed that you haven’t seen tapered wheel bearings in many late-model vehicles. It seems that nearly every vehicle made these days will run some sort of wheel hub assembly. There are a number of reasons for this, but the biggest reason is this: ease of assembly. Not assembly for us, the technicians, but for the assembly line.
Reflashing and reprogramming is a necessary service for repairing vehicles.
Replacing rear wheel bearings on a live axle rear suspension requires a few extra steps when compared to a unitized bearing.
If one of these sensors is replaced, it must be calibrated after it is installed.

The logic behind most ADAS warnings or corrections is to examine the plausibility of the situation.
With the right tools and service information, it is possible to resolve a customer’s complaint.
