Installing an automotive lift is a critical task that demands precision, attention to detail, and adherence to manufacturer instructions. Whether for a professional garage or a private workshop, the process involves a range of preparatory steps, assembly procedures, and safety checks. This guide compiles verified and detailed instructions from multiple official sources to provide a comprehensive overview of auto lift installation, focusing on tools required, step-by-step procedures, and essential safety considerations.
Preparation and Planning
Before beginning any installation, preparation is key. The process involves assessing the workspace, gathering tools, and understanding the specific requirements of the lift being installed. According to the official documentation, the first step is to ensure that the installation environment is clean and free from hazards such as oil or grease on the floor. Tools and materials must be organized and readily available to avoid interruptions.
One of the most important preparatory steps is to thoroughly read the manufacturer’s manual. As stated in the instructions, the manual provides specific details about the model and manufacturer, including cable placement, assembly order, and torque specifications. It is emphasized that while this guide provides general steps, the original manual must be followed to ensure proper installation.
Additional preparation includes verifying the structural integrity of the installation area and confirming that the lift is compatible with the intended use. For instance, if the lift will be used to support heavier vehicles, it is crucial to ensure that the floor and overhead structure can handle the load. The documentation also recommends using step ladders of appropriate height (10–12 feet) and ensuring that all tools are functioning correctly.
Tools and Materials Required
According to the manufacturer’s documentation, the following tools and materials are typically required for a 2-post car lift installation:
- Two 10’ to 12’ step ladders
- ISO 32 Light Hydraulic Oil (approximately 12 quarts)
- Tape measure
- Rotary hammer drill with a ¾-inch drill bit (core drill rebar cutter recommended)
- 4’ level
- Socket and open wrench set (½ inch through 1-1/2 inch; 1-1/8 inch for ¾ inch anchors)
- Vise grips
- 8mm socket head wrench
- Torque wrench
- Teflon tape
It is important to note that the exact toolset may vary depending on the model and manufacturer, and the user is advised to consult the original manual for specifics. The documentation also highlights the importance of using the correct hydraulic oil to ensure the lift operates smoothly and safely.
Disassembly and Modification
If the installation involves modifying the vehicle or frame, the user must prepare for that as well. In some cases, the manufacturer will specify that modifications such as cutting, trimming, welding, or drilling must be performed. During these steps, it is essential to use proper eye and skin protection to prevent injury.
For example, when installing a suspension or leveling kit, the user must elevate the vehicle on a solid, level surface using a floor jack or another lift, and then install jack stands to support the weight. If working on a vehicle without an impact wrench, the user should loosen lug nuts by a half turn while the tires are still on the ground to prevent damage.
When removing wheels and tires, the procedure depends on the type of lift. For leveling kits, typically only the front wheels and tires need to be removed. However, for suspension lifts, all four wheels must be removed. The user is advised to take their time during disassembly to avoid damage to suspension components.
Installation of Lift Arms and Cables
One of the most critical parts of the installation is the proper assembly of the lift arms and cables. The manufacturer’s documentation emphasizes the importance of correct positioning to ensure smooth operation and safety.
The lift arms must be placed in their correct positions, and the headpins must be inserted through the holes in the arm assembly. A snap ring must then be installed into the groove on the headpin. The user is instructed to ensure that the arm restraint gears are properly aligned and that the teeth on the gear ring mesh correctly with the teeth on the arm restraint gears. This alignment is essential for the smooth operation of the lift.
After the arms are in place, the gear ring must be adjusted as necessary to ensure solid engagement with the arm restraint pin assemblies. The user is advised to test the lift arm by moving it from left to right and to confirm that it can support the user’s weight before placing any vehicles on it.
For models with asymmetrical arms—where front and rear arms are of different lengths—the user must consult the manufacturer’s instructions to ensure correct placement. Failure to follow these instructions can result in improper support and potential safety hazards.
Final Assembly and Safety Checks
Once the lift arms and cables are properly installed, the next step is to complete the final assembly. The manufacturer’s documentation outlines several key checks that must be performed to ensure the lift operates safely and efficiently.
One of the first checks is the adjustment of the gear ring. This ensures that all four arm restraint pin assemblies engage the gear ring smoothly. The user is also instructed to inspect the gears periodically to confirm that they remain in the correct position and function properly.
The documentation also highlights the importance of the safety latch system. Once the lift reaches the desired height, the user must lower it into the locked position before working underneath the vehicle. It is explicitly stated that lifts without a functioning safety latch system must not be used, as this poses a serious risk.
Additionally, the user must ensure that the lift is fully lowered before attempting to drive a vehicle onto or off the lift. Before lowering a vehicle, the user must alert anyone in the vicinity and confirm that no tools or equipment are located beneath the car. All doors should be closed before proceeding.
Post-Installation and Maintenance
After the lift is fully installed and operational, the user must perform several post-installation steps to ensure continued safety and performance. These include scheduling regular inspections and maintenance checks.
The manufacturer recommends that the lift be inspected regularly—after the first 500 miles and then every 3,000 to 5,000 miles—for signs of wear or damage. This includes checking for any loose bolts, damaged cables, or misaligned gears. The user is also advised to schedule a professional wheel alignment within 100 miles of installation to ensure proper handling and tire wear.
For users who are not confident in performing the installation themselves, the documentation provides contact information for professional installers. This includes a toll-free number (877-298-7730) and an email address ([email protected]) for assistance in finding qualified technicians in the area.
Safety Guidelines and Best Practices
Safety is a central concern in any auto lift installation. The documentation from multiple sources outlines several best practices to reduce the risk of accidents and injuries.
First, it is strongly advised not to allow customers to drive their own vehicles onto the lift. Insurance companies typically prohibit this practice, and it is considered unsafe. Instead, trained personnel should handle the process to ensure that vehicles are positioned correctly and securely.
The lift area must be kept clean and free of clutter, including tools, extension cords, and hoses. This reduces the risk of tripping and ensures that the lift can operate without interference. The user is also advised to store all tools in their designated places to maintain a safe and organized workspace.
Another important consideration is the weight capacity of the lift. The user must ensure that the lift is capable of supporting the full weight of the vehicle, including any additional loads in the trunk or bed of a truck. Failure to do so can affect the center of gravity and make the lift unstable.
Finally, the user is encouraged to consult the American Lift Institute (ALI) for additional safety resources. The ALI provides a safety tips guide that can be purchased from its website. This guide offers further insights into best practices and safety standards for lift installation and operation.
Conclusion
Auto lift installation is a complex process that requires careful planning, the right tools, and strict adherence to manufacturer instructions. The steps outlined in this guide are based on verified documentation from multiple sources and emphasize the importance of preparation, proper assembly, and ongoing maintenance. By following these guidelines, users can ensure that their lift operates safely and efficiently for years to come.
Whether installing a lift for a professional repair shop or a home garage, users are encouraged to seek assistance from qualified professionals if they are unsure about any step in the process.
