If you’ve ever felt your vehicle’s steering feel loose over a pothole or noticed the back end bounce two or three times after hitting a speed bump, you’ve likely had a close encounter with worn-out shock absorbers. As someone who’s spent the last 12 years supplying shocks to everything from compact commuter cars to light-duty work trucks, I can’t tell you how often I get messages from people who tried to install their own new shocks, only to run into small mistakes that turned into big headaches. This isn’t rocket science—but it does require paying attention to a few key details to get it right. Today, I’m walking you through the process step by step, straight from the supplier’s playbook, no fancy jargon, just real advice that works. Shock Absorber
First, let’s start with the basics: why installing shocks yourself is worth getting right. Worn shocks don’t just make your ride uncomfortable—they wear out your tires faster, throw off your steering alignment, and even compromise your ability to stop in time. When I ship a set of shocks to a customer, I include a spec sheet that’s tailored to their make and model, because a shock that fits a 2018 Honda Civic isn’t the same as one for a 2021 Ford F-150. One of the most common mistakes I see people make is skipping the research step to confirm they have the right parts. Before you even pick up a wrench, cross-reference your vehicle’s VIN number with the part number on the box you got from us. If something doesn’t line up, shoot me a message before you start—we’d rather swap out a part than have you waste hours on a wrong fit.
Next, gather your tools and prep your workspace. You don’t need a fully equipped mechanic’s garage, but you do need a few key items: a jack rated for at least twice your vehicle’s weight (never use a scissor jack alone—they’re for changing tires, not lifting for repairs), jack stands (ratchet-style ones work best for stability), a lug wrench, a socket set that includes deep sockets (shock bolts are often recessed), a breaker bar for stubborn nuts, a small wire brush, and a can of penetrating oil. I always recommend doing this on a flat, paved surface—gravel or dirt can cause a jack to shift mid-repair, which is dangerous. Also, take 10 minutes to clean the area around your old shocks with the wire brush. Mud, rust, and road grime make it almost impossible to loosen bolts, and you don’t want debris falling into your wheel wells during the process.
Safety can’t be overstated here. If you’re lifting the front end, loosen the lug nuts first before you jack the car up—trying to loosen a nut on a lifted wheel is a workout you don’t need. Once the car is lifted, slide the jack stands under the frame, not the control arms or differential. Lower the car onto the stands, and give each corner a small shake to make sure it’s secure. I always keep the emergency brake on and block the opposite wheels when working on one side at a time—this prevents the vehicle from rolling. I’ve seen too many people skip this step, and it’s the number one cause of minor injuries when installing shocks.
Now, let’s get to removing the old shocks. This part is simple, but take your time. For front shocks, you’ll usually find two bolts at the bottom (connecting to the steering knuckle) and one nut at the top (inside the engine bay or under the dashboard, depending on the vehicle). For rear shocks, most have two bolts: one at the bottom connecting to the axle or control arm, and one at the top connecting to the frame. Before you loosen anything, take a photo of the old shock with your phone. It sounds silly, but it’s easy to mix up the orientation of the top bushing or the position of the washers when you’re under the car. Apply a little penetrating oil to each bolt, wait 15 minutes (I often use this time to grab a water and lay out my new shocks on a tarp—keeps things organized), then use the breaker bar to loosen the top nut first, followed by the bottom bolts. Once all fasteners are loose, carefully pull the old shock out. If it’s stuck, don’t yank it—wiggling it back and forth while pulling usually works, and if it’s really rusted, a small rubber mallet to tap the base of the shock will loosen it.
Before installing the new shock, take two minutes to prep it. Even though our shocks come pre-lubricated at the factory, I always put a small dab of anti-seize on the shock bolts and the threads of the top nut. This makes future maintenance way easier, and it prevents rust from seizing the parts together. Also, check the bushings on the new shock—they should fit snugly, and if they feel loose, give them a little push to seat them. Here’s another tip: if your new shocks came with new mounting hardware (we always include this, by the way—old hardware is often worn and should be replaced), use the new parts instead of reusing the old ones. It’s a small step, but it makes a huge difference in how long the new shocks last.
Now, installing the new shock. Start with the top first, because it’s easier to line up once the bottom is secured. For front shocks, feed the top bolt or stud through the mounting point, and for rear shocks, push the top bushing into the frame mount. Hand-tighten the top nut first—don’t use a wrench yet, because you need to adjust the alignment slightly. Next, align the bottom of the shock with the mounting points on the knuckle or axle. This is where that photo you took earlier comes in handy—make sure the shock is facing the same direction as the old one, with the bushings oriented correctly. Hand-tighten the bottom bolts, then go back and torque all fasteners to the specification listed in your vehicle’s service manual. Wait—what’s torque? Torque is the specific amount of tightness each fastener needs, and over-tightening can crack the shock’s mount or strip threads, while under-tightening can cause the shock to rattle or come loose. If you don’t have a torque wrench (another tool worth the $20 or $30 investment), we print a general torque spec for common models on every shock box we ship, and you can also find it for free on automotive forums or manufacturer websites.
Here’s a step most DIYers skip, and it makes a big difference: before you lower the car, press the shock all the way in and let it expand a few times. This seats the internal components of the shock and makes sure it’s moving freely without binding. If it feels stuck at any point, double-check your alignment—you may have the shock turned wrong, or a washer may be out of place. Once the shock moves smoothly, you can torque all fasteners to the correct spec a second time. Lower the car slowly, and when it’s back on the ground, give each wheel a little shake to make sure everything is secure.
If you’re installing shocks on both front or both rear axles, do one side at a time. This keeps the vehicle balanced and prevents it from leaning too far, which can throw off the alignment. If you’re installing all four shocks, I recommend replacing the strut mounts or bushings at the same time—worn mounts can cause noise and vibration, even if your new shocks are perfectly installed. That’s another little tip from the supplier side: we often sell strut mount kits as a bundle with shocks, and I swear by replacing them whenever you swap shocks. It’s a extra $20-$30, and it saves you from going back to the shop a few months later for the same problem.
After you finish installing, take the car for a short test drive around your neighborhood. If you feel any unusual noise (a clunking or rattling over small bumps), pull over and check all bolts—they may need a little more torque. If the ride feels harsher than expected, don’t panic—new shocks need about 100 miles to break in, and they’ll soften up a bit as the bushings settle. If the bounce is worse, double-check that you didn’t reverse the orientation of the shock or skip a washer.
Now, a quick note on when to leave this to the professionals. I get a lot of customers who say they want to save money by installing their own shocks, and most of the time it works out great. But if you’re working on a vehicle with a independent front suspension or a lift kit, or if you don’t feel comfortable with basic tools, it’s okay to hire a mechanic. The average shop charges $100-$150 per axle to install shocks, and that’s money well spent if it means the job is done correctly. Also, if you’ve never worked on a vehicle before, practicing with a set of old, worn shocks you already removed is a good way to get comfortable with the process before handling your new parts.
As someone who’s been in the shock supply business for over a decade, I can tell you that the biggest reward from our products is hearing from a customer who installed their shocks themselves and said their ride feels like a whole new car.
