3. Installation Guidelines
The Fabtech FT66 Suspension Sleeve is a component designed for specific applications within a vehicle's suspension system. Proper installation is crucial for vehicle safety and performance. Refer to your vehicle's specific service manual for detailed instructions on suspension component replacement.
3.1 Pre-Installation
- Verify that the FT66 sleeve is the correct part for your application by checking dimensions and part numbers.
- Inspect the sleeve for any signs of damage or manufacturing defects before installation.
- Gather all necessary tools, including wrenches, sockets, and a torque wrench.
3.2 Installation Steps (General)
- Safely lift and support the vehicle according to manufacturer guidelines.
- Remove the existing suspension component that the sleeve will replace, following vehicle-specific procedures.
- Clean the mounting area thoroughly, removing any dirt, rust, or old grease.
- Carefully insert the Fabtech FT66 sleeve into its designated position. Ensure it seats fully and correctly.
- Reassemble the surrounding suspension components, ensuring all bolts and fasteners are tightened to the vehicle manufacturer's specified torque values.
- Lower the vehicle and perform a visual inspection to confirm proper installation and alignment.
Note: Professional installation is highly recommended to ensure correct fitment and vehicle safety.
4. Function and Application
The Fabtech FT66 Suspension Sleeve is a critical component designed to provide a precise fit and reduce friction or wear between moving parts within a suspension assembly. Its primary function is to act as a bushing or spacer, ensuring proper alignment and smooth operation of suspension linkages. Once installed, the sleeve contributes to the overall structural integrity and performance of the suspension system.
5. Maintenance
The FT66 Suspension Sleeve is a durable component, but regular inspection is recommended as part of routine vehicle maintenance to ensure its longevity and proper function.
- Visual Inspection: Periodically inspect the sleeve and surrounding suspension components for signs of wear, corrosion, cracks, or deformation.
- Cleanliness: Keep the area around the sleeve free from excessive dirt, mud, and corrosive substances.
- Tightness: Ensure all fasteners associated with the suspension assembly remain properly torqued. Loose components can lead to premature wear of the sleeve.
- Replacement: If the sleeve shows significant signs of wear, damage, or if it no longer provides a snug fit, it should be replaced immediately to prevent further suspension issues.
