Installing Lemforder polyurethane bushings on a 250 HP BMW E36 can significantly enhance the car’s handling and performance. This article outlines the process, costs, and results of a DIY installation.
Introduction to Polyurethane Bushings
Polyurethane bushings are popular upgrades for performance vehicles due to their durability and improved handling characteristics. Unlike rubber bushings, polyurethane offers better resistance to wear and provides a firmer connection between the chassis and suspension components.
Benefits of Using Lemforder Polyurethane Bushings
- Enhanced handling and responsiveness
- Increased durability and longevity
- Reduced deflection under load
- Improved steering feedback
Tools and Materials Needed
- Lemforder polyurethane bushings
- Jack and jack stands
- Socket set and ratchet
- Torque wrench
- Pry bar
- Grease
- Safety goggles and gloves
Cost Breakdown
The total cost of installing Lemforder polyurethane bushings on a BMW E36 can vary based on several factors, including the source of the bushings and any additional tools you may need. Here’s a breakdown of typical costs:
- Lemforder polyurethane bushings: $150 – $250
- Tools (if not already owned): $50 – $150
- Miscellaneous supplies (grease, etc.): $20
Overall, the DIY project can cost between $220 and $420, depending on your existing tools and the specific bushings purchased.
Step-by-Step Installation Guide
Step 1: Prepare the Vehicle
Begin by parking the BMW E36 on a flat surface and engaging the parking brake. Loosen the lug nuts on the front wheels while the car is still on the ground.
Step 2: Lift the Vehicle
Use a jack to lift the front of the vehicle and secure it with jack stands. Make sure the car is stable before proceeding.
Step 3: Remove the Front Suspension Components
Remove the front wheels entirely. Then, disconnect the suspension components that are attached to the bushings you will be replacing. This may include the control arms and sway bar links.
Step 4: Remove Old Bushings
Using a pry bar, carefully remove the old rubber bushings from their housings. This step may require some effort, as they can be tightly fitted. Ensure that the housing is clean and free of debris.
Step 5: Install Lemforder Polyurethane Bushings
Apply a small amount of grease to the new polyurethane bushings to facilitate installation. Press the new bushings into the housing, ensuring they are seated properly.
Step 6: Reassemble Suspension Components
Reattach the suspension components that were removed earlier. Make sure to torque all bolts to the manufacturer’s specifications to ensure safety and performance.
Step 7: Reinstall Wheels and Lower the Vehicle
Once everything is reassembled, reinstall the front wheels and lower the vehicle back to the ground. Tighten the lug nuts to the specified torque.
Results After Installation
After completing the installation, many drivers report noticeable improvements in handling and responsiveness. The firmer feel of the suspension helps in cornering and provides better feedback through the steering wheel.
Conclusion
Installing Lemforder polyurethane bushings on a BMW E36 is a rewarding DIY project that can enhance the vehicle’s performance. With the right tools and a bit of patience, you can achieve professional-level results at a fraction of the cost.
