Замена подшипника ступицы МОСКВИЧ 2140 / 412

Introduction

This tutorial provides a step-by-step guide for replacing the wheel hub bearing in a Moskvich 2140 or 412 vehicle. Understanding this process is crucial for maintaining the car's performance and ensuring safe driving. Properly functioning wheel bearings allow for smooth wheel rotation and prevent overheating and damage.

Step 1: Gather Necessary Tools and Materials

Before starting the replacement, prepare the following tools and materials:

• New inner and outer wheel bearings (Inner: 7206A, Outer: 6-7304A)
• Lubricant (Lithol-24 recommended)
• Screwdrivers (flathead)
• Hammer
• Punch or soft metal tool for bearing removal
• Wrench set
• Torque wrench
• Clean rags
• Kerosene for cleaning

Step 2: Remove the Wheel and Brake Components

1. Lift the Vehicle: Use a jack to raise the car and secure it with jack stands.
2. Remove the Wheel: Unscrew the lug nuts and take off the wheel.
3. Detach the Brake Mechanism: Carefully remove the brake caliper and any associated components to access the hub.

Step 3: Disassemble the Hub

1. Remove the Hub Nut: Unscrew the hub nut and take out any retaining clips.
2. Carefully Pull Off the Hub: Gently pull the hub from its spindle. Be cautious as the inner bearing may come off with it.
3. Extract the Seal: Use a flathead screwdriver to pry out the old seal from the hub without damaging the hub itself.

Step 4: Remove Old Bearings

1. Check for Wear: Inspect the inner and outer bearing surfaces for any signs of damage or wear.
2. Press Out the Outer Bearings: Use a punch to drive out the outer bearings with light taps at opposite points around the circumference.
3. Remove the Inner Bearing: If needed, apply gentle hammering to slide the inner bearing off the spindle.

Step 5: Clean and Inspect Components

1. Wash Parts: Clean all disassembled components with kerosene to remove grease and debris.
2. Inspect for Damage: Look for scratches, gouges, or other wear on the bearing surfaces and the spindle.
3. Ensure No Deformation: Particularly check the spindle for any bends or cracks after impacts.

Step 6: Install New Bearings

1. Grease the Bearings: Apply a sufficient amount of Lithol-24 grease to the new bearings.
2. Press in the Outer Bearing: Position the outer bearing in the hub and press it in firmly. Ensure it is seated properly.
3. Install the Inner Bearing: Slide the inner bearing onto the spindle, ensuring it is aligned correctly.

Step 7: Reassemble the Hub

1. Replace the Seal: Install a new seal into the hub, ensuring it sits flush against the surface.
2. Reattach the Hub: Carefully place the hub back onto the spindle and secure it with the hub nut.
3. Reattach the Brake Components: Reinstall the brake caliper and any other components that were removed.

Step 8: Reinstall the Wheel

1. Put the Wheel Back On: Align the wheel with the hub and screw on the lug nuts.
2. Lower the Vehicle: Carefully lower the vehicle back to the ground using the jack.

Step 9: Final Adjustments and Checks

1. Torque the Hub Nut: Use a torque wrench to tighten the hub nut to the manufacturer's specifications.
2. Check for Play: Ensure that there is minimal axial play (0.02-0.12 mm) in the hub.
3. Test Drive: Take the vehicle for a short drive to listen for any unusual noises and check the overall performance.

Conclusion

Replacing the wheel hub bearing in a Moskvich 2140 or 412 is a manageable task that can significantly improve your vehicle's performance. Regular maintenance and timely replacement of worn bearings can prevent more serious issues down the line. If you encounter any unusual noises or performance issues, consider checking the bearings again or seeking professional assistance.
