However, due to the rugged nature of off-roading, the front knuckle can be prone to wear and tear, which can lead to decreased handling and stability.

Signs of a Damaged Front Knuckle

Here are some telltale signs that may indicate a damaged front knuckle on your Polaris Pro XP:

• Unusual noises, such as clunking or grinding, when turning or going over bumps
• Excessive play in the steering wheel
• Difficulty in keeping the vehicle aligned
• Uneven tire wear

Tools and Parts Required

• 17mm socket
• 19mm socket

• Ratchet
• Breaker bar (optional)
• Torque wrench
• New front knuckle

Step 1: Safety First

Before you start working on your Polaris Pro XP, it’s essential to ensure your safety. Park the vehicle on a stable surface, engage the parking brake, and disconnect the negative battery terminal.

Step 2: Remove the Wheel and Brake Caliper

Using the 19mm socket, loosen the lug nuts but do not remove them completely. With the vehicle still on the ground, use the 17mm socket to remove the caliper mounting bolts. Carefully lift the brake caliper and tie it to the suspension to avoid straining the brake line.

Step 3: Disconnect the Tie Rod End

Using the 19mm socket, remove the tie rod end castle nut and washer. Use a pickle fork or a ball joint separator to disconnect the tie rod end from the knuckle.

Step 4: Separate the Upper Ball Joint

Using the 21mm socket, remove the upper ball joint castle nut and washer. Use a pickle fork or a ball joint separator to disconnect the upper ball joint from the knuckle.

Step 5: Remove the Knuckle

With everything disconnected, use the 19mm socket to remove the four knuckle mounting bolts. Carefully pull the knuckle straight out to separate it from the A-arm.

Step 6: Replace the Knuckle Bearings and Seals

Using a press tool or a bearing separator, remove the old knuckle bearings and seals. Clean the knuckle thoroughly and install the new knuckle bearings and seals.

Step 7: Assemble the New Knuckle

Place the new knuckle onto the A-arm and install the four knuckle mounting bolts. Torque the bolts to the manufacturer’s specifications.

Step 8: Reattach the Upper Ball Joint

Align the upper ball joint with the knuckle and install the castle nut and washer. Torque the nut to the manufacturer’s specifications.

Step 9: Connect the Tie Rod End

Connect the tie rod end to the knuckle and install the castle nut and a new cotter pin. Torque the nut to the manufacturer’s specifications.

Step 10: Reinstall the Brake Caliper

Reinstall the brake caliper and secure it with the caliper mounting bolts. Torque the bolts to the manufacturer’s specifications.

Step 11: Reinstall the Wheel

Lift the vehicle off the ground and install the wheel. Tighten the lug nuts by hand, then use the 19mm socket to torque them to the manufacturer’s specifications.
