How to Remove Rear Blocks Safely and Effectively?

Removing rear blocks from a vehicle is a common procedure for adjusting the ride height or restoring the original configuration. Here’s a general guide on how to safely and effectively remove rear blocks from a vehicle:

Gather Necessary Tools and Equipment

Ensure you have the required tools:

  • Jack and jack stands
  • Lug wrench
  • Socket set
  • Torque wrench
  • Safety glasses and gloves

Prepare the Vehicle

  1. Safety First: Park the vehicle on a level surface, engage the parking brake, and chock the front wheels to prevent rolling.
  2. Raise the Rear of the Vehicle: Use a jack to lift the rear of the vehicle and support it securely with jack stands. Make sure to place the jack stands at the appropriate points as per the vehicle’s manual for stability and safety.
  3. Remove Wheels: Use the lug wrench to loosen the lug nuts on the rear wheels. Then, lift the wheels off the vehicle using the jack and place them aside.

Remove Rear Blocks

  1. Access the Blocks: Rear blocks are often located between the rear axle and the leaf springs or on top of the leaf springs. They might be held in place by U-bolts or other fasteners.
  2. Disconnect U-bolts: If the blocks are held in place by U-bolts, use a socket set to remove these bolts. Keep the U-bolts and related hardware in a safe place as they will likely be reused.
  3. Lower the Axle: If the blocks are located between the axle and the leaf spring, slowly lower the rear axle with the jack to release pressure from the blocks. This should allow for easy removal of the blocks.
  4. Remove the Blocks: Carefully take out the rear blocks from their position. If they’re stuck due to corrosion or rust, use penetrating oil and a rubber mallet to tap them gently for removal.

Reassemble and Torque

  1. Reinstall and Torque: If not replacing the blocks, reinstall the components removed, ensuring they’re properly aligned and torqued to the manufacturer’s specifications. If there are new components, follow the manufacturer’s guidelines for installation torque.
  2. Reattach Wheels: Put the rear wheels back onto the vehicle and hand-tighten the lug nuts. Lower the vehicle from the jack stands and then securely tighten the lug nuts with a torque wrench in a star pattern.
  3. Test Drive: After completing the reassembly, take the vehicle for a test drive to check for any unusual noises or issues. If everything seems normal, the removal process was likely successful.

Benefits of Removing Rear Blocks

Rear blocks are a common feature on vehicles, and they can be beneficial in some situations. However, there are also times when removing rear blocks can be beneficial.

Rear blocks help to keep the rear suspension from bottoming out over bumps or uneven terrain.

This helps to provide a smoother ride and better handling of the vehicle. Removing rear blocks can improve the performance of your vehicle in several ways:

Increased Traction

By removing rear blocks, you will increase traction for your vehicle. This is especially important if you plan to take it off-road or drive on wet surfaces.

With increased traction, you will have more control over your vehicle and be able to handle any situation that comes up with ease.

Improved Handling

When you remove the rear blocks from your car, it allows for greater flexibility in its suspension system which leads to improved handling characteristics.

You will find that cornering becomes easier and more precise as well as having an overall smoother feel while driving around turns at higher speeds.

Better Fuel Economy

The removal of rear blocks also results in better fuel economy due to less drag on the engine caused by the extra weight being carried around by the car’s suspension system.

This means that not only do you save money on fuel costs but also reduce emissions released into our atmosphere – making it good for both our pockets and environment!

Reduced Wear & Tear

Without having those heavy duty shocks mounted onto the back of your car, there is less strain put onto other components such as brakes or tires which means they won’t need replacing as often resulting in reduced wear & tear expenses down the road!

Potential Issues with Removing Rear Blocks

Removing rear blocks from a vehicle can lead to several potential issues, which you should be aware of before performing this modification. These issues might impact the vehicle’s handling, suspension, and overall performance:

Altered Ride Height and Handling

When rear blocks are removed, it can significantly alter the vehicle’s ride height. The rear end will sit lower than before, which might affect the vehicle’s overall balance. This change can cause:

  • Handling Differences: The vehicle’s handling characteristics may change, potentially impacting steering responsiveness and stability.
  • Towing Capacity: Removing rear blocks can reduce the vehicle’s towing capacity. The lower rear end might affect the weight distribution and compromise the ability to tow heavy loads safely.

Suspension Components Stress

Removing rear blocks can put stress on other suspension components:

  • Increased Load on Leaf Springs: With the blocks removed, the leaf springs might experience increased stress as they support the vehicle’s weight differently.
  • Rear Shocks: Altered suspension geometry might affect the performance of the rear shocks, potentially causing premature wear or affecting their effectiveness.

Warranty and Legal Issues

Making modifications, including removing or altering OEM components like rear blocks, might affect the warranty and could potentially be illegal in some areas:
