Wheel Bearings And Wheel Speed Sensors

If you are replacing a wheel bearing on a late-model vehicle, you will be dealing with a wheel speed sensor.

VIDEO: Pre-Loading Bearings: What’s Going On Inside?

Andrew Markel discusses pre-loading wheel bearings, and how it affects the geometry of the inside of the bearing.

VIDEO: Pre-Loading Wheel Bearings Off The Vehicle

Andrew Markel discusses wheel bearings, and how the process of orbital forming is important to pre-loading bearings off the vehicle.

Andrew Markel discusses Gen 1 wheel bearings, and how this simple wheel bearing can be the most complicated to install.

Wheel Bearings And Locking Hubs

Automatic hubs are used on many 4×4 trucks to disengage the front wheels when four-wheel drive is not needed. Disconnecting the front wheels reduces friction and may improve fuel economy as much as one mile per gallon depending on the vehicle. A one mpg difference may not sound like much, but every little bit helps.

Busted Knuckles: Bearings And Seals For Monobeam Front Axles

Servicing the ball joints and U-joints on monobeam axles requires a fair amount of steering knuckle disassembly just to access these components.

Wheel Bearings: Diagnostics, Removal And Installation

The classic symptom of a bad wheel bearing is typically a cyclic chirping, squealing or growling noise that changes in proportion to vehicle speed.

Engine Bearings Under Pressure

Engine bearings have to withstand punishing loads in today’s engines. Smaller displacements, turbocharging and higher horsepower ratings mean crankshaft and connecting rod bearings are being subjected to heavier loads. This has led to the development of some new bearing alloys and coatings that enable these parts to survive.
