Properly disposing of old suspension parts is a critical responsibility for Nashville vehicle owners, repair shops, and enthusiasts. Suspension components such as springs, shocks, struts, control arms, and ball joints are not just bulky metal scrap—they often contain residual fluids, heavy metals, and synthetic materials that can harm the environment if handled carelessly. Nashville’s unique mix of urban development and natural waterways makes responsible disposal especially important to protect local ecosystems and maintain community safety. This guide provides a comprehensive look at how to dispose of old suspension parts in compliance with Nashville regulations, why it matters, and where to find authorized facilities and services.

Why Proper Disposal Matters

Old suspension parts pose several environmental and legal risks. Shocks and struts typically contain hydraulic oil and nitrogen gas under pressure. Over time, these fluids can leak, contaminating soil and groundwater. Control arms and springs are often coated with rust inhibitors or painted with finishes that may contain chromium or other heavy metals. When dumped in landfills or ditches, these substances can percolate into the Nashville area’s watershed, affecting everything from the Cumberland River to local reservoirs.

Illegal dumping of automotive parts carries significant penalties in Nashville. Under Metro Nashville Code, illegal dumping can result in fines starting at $500 and increasing for repeat offenses. Additionally, improper disposal can lead to citations from the Tennessee Department of Environment and Conservation (TDEC). Beyond fines, the cost of environmental cleanup often falls on property owners or businesses, which can run thousands of dollars.

From a health perspective, contact with leaked hydraulic fluids can cause skin irritation and, with prolonged exposure, more serious conditions. Old suspension parts may also harbor sharp edges or broken coil springs that pose physical injury risks during handling. Proper disposal mitigates these hazards and keeps Nashville’s neighborhoods, parks, and water bodies safe for everyone.

Steps to Dispose of Suspension Parts in Nashville

Follow these detailed steps to ensure your old suspension parts are handled correctly. Each step is designed to meet Nashville’s waste management requirements and maximize recycling opportunities.

Step 1: Identify Recyclable Materials

Most suspension parts are primarily constructed of steel, aluminum, or cast iron—all highly recyclable. Shocks and struts have a metal tube and rod, while springs are made from hardened steel. Control arms and sway bars are typically stamped steel or aluminum. However, some components may contain non-metal inserts like rubber bushings, plastic dust boots, or urethane bushings. Before disposal, separate these non-metal parts if possible, as many recyclers prefer clean metal streams. Nashville recycling centers often accept whole assemblies but may charge extra for parts with attached rubber or plastic.

Step 2: Drain Fluids Properly

Shocks and struts are sealed units containing hydraulic oil and sometimes pressurized nitrogen gas. In Tennessee, it is illegal to dispose of these without draining or recycling the fluid. To drain: secure the shock in a vise, puncture the tube near the bottom with a punch or drill (wear safety glasses and gloves), and collect the fluid in a sealable container labeled “Used Hydraulic Oil.” For gas-pressurized units, slowly release the gas by depressing the valve stem with a screwdriver before puncturing. Take the collected oil to a Nashville Household Hazardous Waste facility or an auto parts store that accepts used oil. Many retailers like Advance Auto Parts and AutoZone accept up to five gallons per visit at no charge.

Step 3: Contact Local Recycling Centers

Nashville offers several options for recycling suspension parts. The Nashville Public Works Department operates drop-off centers for scrap metal. The Nashville’s Recycling Drop-Off Center at 1417 Corporate Court accepts ferrous and non-ferrous metals. Call ahead (615-880-1000) to confirm they accept automotive suspension components. For large quantities, commercial scrap yards like Southern Scrap Recycling or PSC Metals in Nashville buy clean steel and aluminum, offering per-pound rates. Always verify that the yard is licensed and follows environmental regulations.

Step 4: Visit Nashville’s Waste Management Website

The Nashville Public Works – Waste Management page provides schedules for hazardous waste collection events, permanent drop-off locations, and residential curbside pickups. Search for “automotive parts disposal” or “scrap metal” on their site. They also list guidelines for what can go in regular trash versus what requires special handling. As of 2025, Nashville offers monthly Household Hazardous Waste collection days at various locations—check the online calendar for the next event near you.

Step 5: Use Authorized Disposal Services

If you have a large volume of suspension parts from a repair shop or fleet operation, hiring a licensed waste disposal company is the safest and most compliant route. Companies like Clean Harbors, Republic Services, and Waste Management of Tennessee offer pick-up and processing for automotive waste. The Tennessee Department of Environment & Conservation maintains a list of certified transporters and disposal facilities. Ensure the service provider is permitted to handle used oil filters, hydraulic fluids, and scrap metals. Request documentation of proper disposal for your records, especially if you are a business subject to environmental audits.

Additional Tips for Safe Disposal

Safety should be your priority when handling old suspension parts. Wear cut-resistant gloves, safety glasses, and sturdy boots. Coil springs under tension can snap and cause injury—use spring compressors if you disassemble them. Transport fluids in secure containers placed in a plastic bin to catch any leaks. Never leave parts curbside without a scheduled pickup; this constitutes illegal dumping. If you have partial parts (e.g., a broken ball joint), check with local auto parts stores—some accept used cores for recycling. Avoid burning suspension components; the smoke can release toxic fumes, and burning is prohibited by Nashville air quality regulations.

Consider coordinating with a local vocational school or auto shop program that might use old suspension parts for teaching. Some Nashville high schools with automotive programs accept donations of clean, non-fluid parts. Contact the Nashville Auto Diesel College or TN STEM Lab to see if they have a need. Donating extends the life of the parts and reduces waste.

Common Questions About Suspension Part Disposal

Can I put old shocks in my regular trash?

No. Shocks and struts contain hydraulic fluid and pressurized gas, making them hazardous waste in Tennessee. They must be drained of oil and depressurized before disposal. Even if drained, the metal can be recycled—placing them in the trash is illegal and may result in fines.

Are coil springs recyclable?

Yes, coil springs are made of steel and can be recycled with other scrap metal. However, they can be under tension. If you are removing them yourself, use a spring compressor. Some scrap yards require springs to be cut into manageable lengths—call ahead for their policy.

Is there a fee for dropping off suspension parts at Nashville recycling centers?

Generally, no, if you deliver them to the Metal Recycling Drop-Off Center. However, if you have mixed loads containing non-metal waste, there might be a charge for processing. Residential hazardous waste events are free for Nashville residents. Commercial entities may face small fees for large volumes.

What about control arms with rubber bushings?

Rubber bushings are not recyclable with metal. You can either remove them before recycling the metal (using a press or torch) or accept that the scrap yard might deduct the weight of the rubber. Some yards accept entire assemblies but pay a lower rate for “shredder feed” rather than clean scrap.

The Importance of Recycling Metals

Recycling suspension parts conserves natural resources and reduces energy consumption. According to the Environmental Protection Agency, recycling steel saves about 60% of the energy needed to produce new steel from raw ore. Aluminum recycling saves up to 95% of that energy. Nashville’s recycling infrastructure supports closed-loop manufacturing: your old control arm can become part of a new car frame or a bridge beam. Choosing to recycle rather than landfill keeps thousands of tons of metal out of Middle Tennessee landfills each year, extending their life and reducing methane emissions from decomposing waste.

Furthermore, recycling metals reduces the demand for mining, which can damage habitats in other parts of the country. By responsibly disposing of your suspension parts, you contribute to a circular economy that benefits the local environment and economy. The National Automobile Recycling Association estimates that the automotive recycling industry in the U.S. supports over 140,000 jobs and processes about 12 million vehicles annually. Nashville participates in this national system through its scrap yards and recycling centers.

Final Considerations for Nashville Residents

Whether you are a weekend mechanic replacing worn struts or a shop owner managing a pile of old springs, following Nashville’s disposal rules is straightforward when you know where to go. Stay up-to-date by bookmarking the Nashville Public Works waste disposal page and signing up for notifications about hazardous waste collection events. When in doubt, call ahead to confirm that a facility accepts your specific parts. Remember: draining fluids, separating materials, and choosing recycling over dumping protects Nashville’s water, soil, and air. It also sets a positive example for the next generation of automotive enthusiasts in the community.
