Greasing a strut primarily involves lubricating its associated components like the turn plate, strut bearings, and bushings using both aerosol oil and injected grease after safely lifting the vehicle and removing the wheel. This process helps ensure smooth operation and extends the lifespan of these critical suspension parts.
Why Lubricate Strut Components?
Lubricating the components surrounding your vehicle's struts, such as the turn plate, strut bearings, and bushings, is crucial for maintaining optimal suspension performance. Proper lubrication helps to:
- Reduce Friction: Minimizes wear and tear on moving parts.
- Prevent Squeaks and Noises: Eliminates common sounds caused by dry or worn components.
- Improve Steering Response: Ensures smoother rotation of the strut assembly during turns.
- Extend Component Life: Protects parts from corrosion and premature failure.
- Enhance Ride Comfort: Contributes to a smoother and more stable driving experience.
Tools and Materials Needed
To effectively lubricate your strut components, you will generally need the following:
- Vehicle Jack: To lift the vehicle.
- Jack Stands: For safety to support the vehicle once lifted.
- Lug Wrench: To remove the wheel.
- Aerosol Can of Penetrating Oil/Lubricant: For initial cleaning and light lubrication.
- Grease Syringe: A specialized tool to inject grease into tight spaces.
- Automotive Grease: High-quality lithium or synthetic grease suitable for chassis components.
- Safety Gloves and Glasses: For personal protection.
Step-by-Step Guide to Greasing Strut Components
Based on the information provided by Palumbo's Automotive (2021), the process for lubricating strut-related parts involves a few key steps:
1. Preparation and Access
- Step 1: Raise the Vehicle Safely
Begin by using a jack to raise the vehicle to a comfortable working height. Always place jack stands under the vehicle's frame for safety before working underneath it. - Step 2: Remove the Wheel
Once the vehicle is securely supported, use a lug wrench to take off the wheel corresponding to the strut you wish to lubricate. This will provide direct access to the strut assembly and its associated components.
2. Lubrication Process
- Step 3: Apply Aerosol Oil
With the wheel removed, locate the turn plate, strut bearings, and bushings. Use an aerosol can of oil to spray lubricant on these specific areas. This initial spray helps to clean away any loose dirt or rust and provides a base layer of lubrication, penetrating into tight crevices. - Step 4: Inject Grease
Next, fill the syringe with grease and inject grease directly into the turn plate, strut bearings, and bushings. The syringe allows for precise application, ensuring the grease reaches the internal friction points. This step provides a more durable and long-lasting lubrication compared to the aerosol oil.
3. Post-Lubrication
After applying the grease, reattach the wheel securely and carefully lower the vehicle using the jack. Repeat the process for any other struts or suspension components that require lubrication.
Quick Reference Table for Strut Lubrication
| Step | Action | Primary Tools/Materials | Target Components |
|---|---|---|---|
| 1 | Raise Vehicle | Jack, Jack Stands | N/A |
| 2 | Remove Wheel | Lug Wrench | N/A |
| 3 | Spray Oil | Aerosol Oil/Lubricant | Turn Plate, Strut Bearings, Bushings |
| 4 | Inject Grease | Grease Syringe, Automotive Grease | Turn Plate, Strut Bearings, Bushings |
Important Tips for Effective Lubrication
- Regular Maintenance: Incorporate strut component lubrication into your routine maintenance schedule, especially if you drive in harsh conditions or notice early signs of wear (e.g., squeaking).
- Quality Lubricants: Always use high-quality automotive-grade oil and grease that are suitable for suspension applications.
- Safety First: Never work under a vehicle supported only by a jack. Always use jack stands.
- Inspect for Wear: While lubricating, take the opportunity to inspect the components for any signs of excessive wear, cracks, or damage, which may indicate a need for replacement rather than just lubrication.
