Here's a general outline of the process. Again, this is NOT a substitute for a repair manual. Variations exist between different S-10 models and years.
Tools You'll Likely Need:
* Jack and jack stands: Safety first! Secure the vehicle properly.
* Wheel chocks: Essential for added safety.
* Lug wrench: To remove the wheel.
* Socket set and wrench set: Various sizes will be needed.
* Ball joint separator: To separate the ball joint from the steering knuckle.
* Tie rod separator: May be needed, depending on how you disconnect the tie rod.
* Hammer and punch: For various tasks, including driving out the old bearing.
* Bearing packing tool: If using a bearing that requires packing with grease.
* Torque wrench: Absolutely essential for tightening components to the correct specification.
* Penetrating oil: To help loosen rusted or seized parts.
* Clean rags or shop towels: To keep things clean.
* New front wheel bearing and seal: Make sure you get the correct parts for your specific S-10 Blazer.
General Steps (Consult your repair manual for specific details):
1. Safety First: Secure the vehicle on jack stands, engage the parking brake, and use wheel chocks.
2. Remove the Wheel: Remove the lug nuts and the wheel.
3. Disconnect Brake Caliper: Remove the brake caliper and hang it safely out of the way. You might need to support it with a bungee cord or wire.
4. Disconnect the Tie Rod: Separate the tie rod end from the steering knuckle. This usually involves using a tie rod separator.
5. Disconnect the Ball Joint: Separate the ball joint from the steering knuckle. This often requires a ball joint separator tool. Be careful not to damage the ball joint boot.
6. Remove the Steering Knuckle: Remove the steering knuckle from the spindle. There may be bolts or cotter pins to remove.
7. Remove the Old Bearing: The old bearing usually needs to be pressed out using a bearing puller or similar tool. This can be tricky; some damage to the old bearing is often unavoidable.
8. Install the New Bearing: The new bearing is usually pressed in using a bearing installer or a socket of the correct size and a press. Ensure it's seated properly and flush.
9. Install the New Seal: Install the new seal if needed, ensuring it's properly seated.
10. Reassemble: Reassemble the components in the reverse order of disassembly. Pay close attention to the correct order and torque specifications.
11. Torque Specifications: Use a torque wrench to tighten all bolts and nuts to the manufacturer's specified torque values (found in your repair manual). This is crucial to avoid premature component failure.
12. Test Drive: After reassembly, test drive the vehicle to ensure the bearing is functioning correctly. Listen for any unusual noises.
Important Considerations:
* Hub Assembly vs. Separate Bearing: Some S-10 Blazers use a hub assembly that includes the bearing, making replacement simpler. Others have a separate bearing and require more steps. Your repair manual will clarify this.
* Pressing Tools: Pressing the bearings in and out often requires specialized tools. You may need to rent these or have a mechanic perform this step.
* Pre-packed vs. Pack-in-place: Some bearings come pre-packed with grease, others require you to pack the grease in yourself.
This is a complex job; if you're not comfortable working on your vehicle's suspension, it's best to have a qualified mechanic perform the repair. Improperly installed wheel bearings can lead to serious safety issues. Always prioritize safety and consult your repair manual.
