Driveline Parts Features

  • Wheel Hub Assemblies
  • CV Boot Kits

    • Why are Wheel Hub Assemblies Important?

      Wheel hub assemblies connect your vehicle’s wheels and rotor to the caliper and allow smooth rotation. They are typically attached to the steering knuckle or rear axle flange/spindle, and depending on the application, they may feature ball or tapered rolling elements.
      Designed to minimize friction and support the wheel load , wheel hub assemblies reduce the resistance of your wheels when in contact with the road. They also control wheel positioning, which determines several performance factors, including tire wear, braking control, vehicle stability in both straight lines and turns, and overall vehicle handling.
      Wheel hub assemblies may be considered an important part of a vehicle’s ABS, TCS and ESC systems. Based on continuous inputs from the integrated ABS sensor, these control systems ensure safe operation.

      Requirements for Wheel Hub Assemblies Include:

      • Precision machining of raceway and flanges
      • Premium rolling elements (optimized size, finish and material)
      • High-quality lubricating grease
      • Durable seal construction and material
      • Accurate ABS sensor signal and plug
      • Exact orbital roll forming

      Designed as pre-assembled units, wheel hub assemblies feature precision machined rolling elements, seals, mounting flanges and commonly, integrated ABS sensors. They are pre-adjusted and pre-set, so they require no maintenance.

      Automotive Applications Use Two Types of Rolling Elements

      Ball Bearings/Sphere Shaped Rolling Elements
      Double row angular contact wheel bearings work best in light- to medium-duty applications. They have a good capacity to handle radial and axial load, and their compact design saves on weight.

      • Tapered/Cone Shaped Rolling Elements: Used for larger vehicles and heavy-duty applications, tapered rolling elements have an excellent capacity to handle radial and axial load. They feature a cup and cone design.
      • Cup and Cone Design: This design is used in pairs on front or rear non-driven wheels. Setting the preload is mandatory, and because they don’t have an integrated seal, maintenance is required. Repack with grease periodically.

      Generations

      Although most OEM manufacturers have moved to a unitized Generation 3 design, the vehicle aftermarket has the following versions available.

      Generation 3
      • Third generation wheel hub assemblies can be used on driven or non-driven axles.
      • Use compact double row ball bearings or tapered rollers which cannot be disassembled
      • Come as a complete unit with two flanges for securing to the knuckle and brake rotor/wheel
      • Pre-set bearing clearance
      • Orbital or roll formed
      • Pre-greased and maintenance free
      • May feature an ABS encoder ring
      Generation 2
      • Second generation wheel hub assemblies can be used on driven or non-driven axles.
      • Use compact double row ball bearings which cannot be disassembled
      • Feature an additional hub or mounting flange with a rotating inner or outer ring
      • Pre-greased and maintenance free
      • May feature an ABS encoder ring
      Generation 1
      • First generation wheel bearings can be used on front and rear axles.
      • Found on many passenger and light commercial vehicles
      • Compact double row design which cannot be disassembled
      • Pre-greased and maintenance free
      • May feature an ABS encoder ring
      THE MEVOTECH™ EDGE

      What makes Mevotech wheel hub assemblies so great? Mevotech gives technicians the edge, by innovating every chassis component.

    • Why are CV Boot Kits Important?

      In automotive applications, this type of boot can be found on inboard and outboard CV (Constant Velocity) joints and prop shafts. CV boots keep moisture, dirt and other debris particles sealed out, preventing contamination of the internal parts of CV joints. They also keep lubrication sealed in, ensuring maximum part life.
      The primary causes of CV boot failures are undesired friction and heat, as well as puncturing. This component faces constant exposure, pelting from road debris and thermal cycling. To ensure optimal part life, requirements for CV boots include:

      • High- and low-temperature resistance
      • Puncture, abrasion and chemical resistance
      • Resistance to flex fatigue
