Can I install these bearings myself and what should I watch for?

Wheel bearing replacement often requires specialty tools and experience removing hubs, seals, and pressing bearings in and out. If you’re not familiar with press-fit installation or torque procedures, professional installation is recommended to ensure safety and longevity.

• Requires hub puller/press, proper seals, and torqueing to manufacturer specs.
• Replace seals and clean mating surfaces during installation for best results.
• If unsure, have a qualified mechanic perform the installation to avoid damage.
