FAQ

Where's the easiest place to buy replacement auto parts?

Short answer: A large retailer that sells auto parts both online and in stores is often the most convenient option.

Why: such retailers typically let you browse parts from home, check basic compatibility, choose delivery or curbside/in-store pickup, and get help from store associates if needed. When choosing, look for clear part descriptions, user reviews, and an accessible return policy. Keep your vehicle information handy to speed selection and reduce mistakes.

  • Tip: Save order numbers and receipts in case you need an exchange or help later.

How do I check part fitment for my vehicle?

Start by gathering your vehicle details: year, make, model, engine size, and VIN if available. Use that info when searching for parts and compare it to the part's listed fitment details.

  • Check product descriptions and any compatibility notes.
  • Compare measurements or specifications if provided.
  • Take photos of the existing part or connector to compare visually.
  • If unsure, contact customer service or ask a store associate to confirm fitment before ordering.

These steps can reduce returns and ensure you buy the right replacement part.

What should I bring to the store for a part exchange?

Bring items that speed up the exchange and help associates verify the part:

  • Original receipt or order confirmation (printed or on your phone).
  • The old part you removed, if possible, so it can be compared.
  • Your vehicle details (VIN, year/make/model) and any photos showing where the part fits.
  • Packaging and labels, if you still have them.

Also be prepared to provide ID for certain purchases. Policies vary by retailer, so check the return/exchange window and condition requirements before you go.

How do I install a replacement part safely?

Basic safety tips can help, but installation methods vary by part and vehicle. Follow manufacturer instructions when available and consider professional help for complex jobs.

  • Work on a level surface and use proper supports (jack stands for lifted vehicles).
  • Wear safety gear like gloves and eye protection.
  • Disconnect the battery before electrical work.
  • Use the correct tools and torque specifications.
  • Test the vehicle in a controlled setting after installation.

If you're unsure at any step, consult a professional mechanic to avoid damage or injury.

What are my options if a part doesn't fit or fails soon after?

If a part is wrong or fails shortly after purchase, start by gathering your paperwork—receipt, order number, and photos showing the issue. Then consider these options:

  • Request an exchange or return under the retailer's return policy.
  • Contact customer service for help with troubleshooting or next steps.
  • Check whether a warranty or manufacturer coverage applies and follow their claims process.
  • Get a professional diagnosis to confirm whether the part or installation caused the problem.

Keeping documentation and acting promptly makes resolving the issue easier.

Keep Your Vehicle in Great Condition with Top Auto Parts

Whether you consider yourself a gearhead or prefer knowing that your vehicle is maintained in top condition for safety on the road, we have the auto parts you need to keep your ride running well. This extensive inventory includes items that are easily replaceable, like wiper blades and headlights, along with parts that require more auto repair knowledge, such as brakes, spark plugs and suspension systems. No matter your level of auto-maintenance prowess, it's easy to find the part for your project when you know exactly what you need.

Filters and hoses

Although there are many places where you can take your car to get you oil changed and fluid levels topped off, there's something satisfying about changing your own oil and replacing belts and hoses that are getting too old. Unlike other projects that take place under the vehicle hood or chassis, changing the oil is something even novices can do if they have the space, the right tools, and the replacement oil and filter. Check your owner's manual to determine which oil filter is appropriate for your vehicle before undertaking this task. Walmart carries a complete line of replacement filters and different types of oil, depending on your climate and style of driving. If you have belts that squeak or hoses that have cracks, it's easy to replace them with the manufacturer-recommended replacements parts. Check the other filters you have on your vehicle, such as an air filter or fuel filter, and replace them at the recommended time.

Batteries and spark plugs

Batteries, for the most part, are also an easy replacement when your vehicle needs a new one. However, some batteries are placed in different positions depending on the vehicle and may require you to move other components and parts out of the way before you're able to access the battery. When selecting a battery, determine the size of the battery you need, the desired cold crank amps, and the necessary voltage. You can also purchase based on group size; 24 and 24F are common options. Spark plugs are the parts that provide the electric current to fire your vehicle's engine. These days, they last much longer than they did even 20 or 30 years ago, but still require replacing from time to time. This is done using a socket wrench with a long handle.

Lights

Being able to see, especially in the dark or inclement weather situations, is crucial when operating a vehicle. This goes for the exterior lighting as well as interior illumination. If you need to replace the headlights or taillights on your vehicle, it's easy to simply change a bulb or completely replace the style of the headlights for a new look or brighter appearance with halogen and xenon replacement bulbs for headlights. These are available for both regular headlights and high-beam headlights. Fog lights and taillight replacement bulbs are available, and interior lighting options include bulbs that work with mirrored lighting and overhead lamps.

Suspension systems

For those do-it-yourselfers with a little more auto-repair knowledge, more difficult tasks like replacing the suspension parts on your car, truck, SUV or other vehicle is possible. The parts you'll need include shock absorbers and struts. In some cases, it's only necessary to replace an individual part, such as a shock absorber. However, sometimes, the replacement is much more involved, such as when an entire strut assembly must be replaced. All our suspension replacement parts are from top brands and highly recommended by vehicle manufacturers as replacement parts. Many of these types of parts also come with a limited warranty.

Brakes

Similar to the suspension system, another crucial part of your vehicle is its braking system. There are many parts that make up the brake system. In addition to the brakes, which are typically either disc or drum style, you may also need rotors or replacements for the brake line's reservoir and hoses. In addition to the individual parts, you can also find brake kits that include all parts needed for a brake change.

Other replacement parts

As a vehicle ages, it becomes necessary to replace many of the parts that incur daily wear. Although major parts like an engine may never have to be replaced, many other parts on a vehicle will be changed at least once during a vehicle's lifetime. When it comes to replacing items related to your auto's air conditioning or heating system, or motors that operate the wiper blades or any of the various switches, sensors and other parts that make up your vehicle, Walmart carries what you need. In addition, we carry a complete line of tools to help you facilitate these repairs.
