🔧 XT4 - Wheel Bearing Replacement
On your XT4, the wheel bearing is typically replaced as a complete hub/bearing assembly (the bearing is built into the hub). The exact steps and torque specs change depending on whether you’re doing the front or rear, so I need one detail before I give you the correct, dealership-accurate procedure.
Difficulty Level: Intermediate | Estimated Time: 1.5-3.0 hours (per side)
⚠️ Safety & Precautions
- 🧤 Support your XT4 with jack stands; never rely on a jack alone.
- ⚠️ Do not let the brake caliper hang by the hose; support it with a hanger.
- ⚠️ If the hub is stuck, avoid hammering the axle threads directly.
- 🔌 No battery disconnect is usually required for this job.
