The Essential Guide to Rear Axle Bearing Puller Tools

Replacing rear axle bearings is a crucial task in maintaining your vehicle's performance and safety. Rear axle bearing puller tools are indispensable for this task, making it easier and more efficient to remove the old bearings and install new ones. This comprehensive guide will provide you with all the information you need about rear axle bearing puller tools, including their types, applications, and how to use them effectively.

Types of Rear Axle Bearing Puller Tools

There are two main types of rear axle bearing puller tools:

Mechanical Pullers

• Lever-type pullers: Utilize a lever to generate force for removing bearings.
• Slide hammer pullers: Use a weighted hammer to create an impact force, dislodging the bearing from the axle.

Hydraulic Pullers

• Hydraulic pullers: Employ hydraulic pressure to push the bearing off the axle. These pullers provide more controlled and consistent force than mechanical pullers.

Choosing the Right Rear Axle Bearing Puller Tool

The type of puller tool you choose depends on several factors:

• Bearing size and type: Different bearings require different types of pullers.
• Vehicle make and model: Some pullers are designed for specific vehicle models.
• Ease of use and safety: Consider the ease of operation and safety features of the puller.

Step 3: Selecting the Puller

• Choose the appropriate puller based on the bearing type and size.
• Attach the puller to the bearing hub.

Step 4: Applying Force

• Mechanical pullers: Apply force to the lever or use the slide hammer.
• Hydraulic pullers: Use the hydraulic pump to generate the required force.

Step 5: Removal

• Gradually increase the force until the bearing is detached from the axle.
• Carefully remove the puller and the bearing.
