That annoying clunking sound over every bump. Your steering wheel feels loose and vague. These aren’t just minor irritations - they’re warning signs that your car’s suspension system needs help.
The problem usually comes from worn shock or strut mounts. This small part plays a huge role. It connects your strut assembly to your car’s frame.
This guide breaks down quality, performance, and true top brand replacement cost in simple terms. We’ll help you choose between OEM replacement shock and strut mounts and aftermarket options. You’ll restore your car’s smooth ride without breaking the bank.
Identifying Strut Mount Failure
The Annoying Clunk and Vibration
Most drivers notice problems through sound and feel first. Online car forums are full of people seeking help with similar issues.
“I have a 2018 Honda Accord, and lately, I hear a ‘clunk’ from the front right every time I go over a speed bump or pothole. The steering also feels a bit loose. My friend said it might be the strut mount.”
This Reddit r/MechanicAdvice post shows the classic warning signs. The noise usually comes first. But when your steering feels different, you know something is failing.
A Real-World Case Study
Bad strut mount symptoms get worse over time. What starts as a small noise can become a serious safety problem.
This detailed post on a Toyota 4Runner forum shows exactly how problems develop. The owner first heard a “clunk” and felt something “loose.” Eventually, the steering got worse and vibrations increased.
The mechanic confirmed failed strut mounts. After replacement, the owner saw immediate improvement. The ride felt “like new” with tight steering and no unwanted noise.
Your Diagnostic Checklist
Use this checklist to figure out if your strut mount is causing problems.
• Unusual Noises: Listen for clunking, popping, or creaking from the suspension. These sounds are most obvious when turning at low speeds or driving over bumps.
• Excessive Vibration: A failing mount can’t absorb vibrations properly. You’ll feel them through the steering wheel as a constant, subtle shake.
• Uneven Tire Wear: A bad mount affects your car’s alignment. Run your hand over your front tires. If you feel alternating high and low spots (called “cupping” or “scalloping”), it signals worn suspension parts.
• Poor Steering Response: Your steering might feel loose or less precise. The wheel might not return to center on its own after turns.
• Visible Wear or Damage: Park safely and check under the hood. Look at the top of the strut towers. You might see cracked or separated rubber. Have someone turn the steering wheel while you watch the center nut - excessive movement means failure.
OEM vs. Aftermarket Debate
Is OEM Worth the Cost?
Car owners face a big question: Is paying extra for an OEM part really worth it? The price difference between manufacturer parts and aftermarket options can be huge - often double or more.
This price gap creates confusion. Is the expensive part actually better, or are you just paying for the brand name? The answer depends on understanding what each option offers and what you need.
What ‘OEM’ Really Means
To make a smart choice, you need to understand the terms.
• OEM (Original Equipment Manufacturer): This is the exact same part installed at the factory. It’s made by or for your car’s manufacturer and comes in branded packaging.
• OES (Original Equipment Supplier): This part comes from the same company that supplies the manufacturer. For example, if Bilstein makes strut mounts for BMW, an OES part would be the same Bilstein mount in a Bilstein box instead of BMW packaging. You get OEM quality, often at a lower price.
• Aftermarket: Any third-party company makes these parts. Quality, materials, and prices vary dramatically - from budget options to high-performance upgrades.
Why OEM Parts Cost More
OEM parts cost more for good reasons focused on precision and reliability.
• Guaranteed Fitment: OEM parts match your vehicle’s exact specifications. This eliminates guesswork and ensures perfect fit, which matters for suspension parts.
• Consistent Quality: Car manufacturers have strict standards for materials, durability, and performance. OEM parts meet these standards and provide the same ride quality as original parts.
• Warranty Support: OEM parts typically come with manufacturer warranties. You get extra protection and support through dealership networks.
The value of perfect fit and finish is significant. According to IHS Markit (now part of S&P Global), demand for OEM-certified parts stays high. Professionals and consumers choose them to maintain vehicle value and ensure proper function.
The Aftermarket Advantage
While OEM offers certainty, aftermarket provides compelling benefits in cost and choice.
• Cost Savings: This is the main reason people choose aftermarket. You often find quality parts for much less than OEM prices.
• Variety and Performance Upgrades: Aftermarket offers more options. Brands may make parts that exceed OEM specs for heavy-duty use or provide sportier feel for performance fans.
• Wider Availability: For older or uncommon vehicles, aftermarket parts are often easier to find than OEM parts, which may be discontinued.
For many vehicles, high-quality aftermarket parts like the Shock Absorber MG offer great balance. You get OEM-level performance with significant savings, making it a smart choice for savvy owners.
Top Brand Replacement Cost
PAA: Average Replacement Cost?
People often ask: What does it cost to replace strut mounts? Total cost to replace a pair of strut mounts typically ranges from $200 to over $800.
This wide range exists because final price depends heavily on your vehicle’s make and model, parts type (OEM vs. aftermarket), and local labor rates.
Cost Comparison Table
Here’s a detailed breakdown comparing costs for different strut mount tiers. This table assumes replacing a pair of front mounts, which is standard practice.

Don’t Forget “Hidden” Costs
Parts and labor for mounts are only part of the total cost. Several other expenses are often necessary for proper repair.
• Wheel Alignment: This is crucial. Replacing strut mounts changes your vehicle’s suspension geometry. Four-wheel alignment is almost always required for proper handling, to prevent tire wear, and ensure straight driving. Expect $80 to $150.
• Related Parts: Since the entire strut assembly comes out, this is perfect timing to replace other worn parts. This concept is called “while you’re in there.” It’s cost-effective to replace struts/shocks, strut bearings, and dust boots at the same time. You avoid paying for the same labor twice soon after.
Most ASE-certified technicians, like those cited by trusted sources like AAA, recommend replacing struts and mounts in pairs (both front or both rear). This ensures balanced handling, predictable performance, and even wear.
DIY vs. Professional
A DIYer’s Spring Compressor Story
Deciding whether to do this job yourself or hire a professional is a major choice. While many DIYers succeed, the process involves significant risks you shouldn’t underestimate.
Many DIYers, like users on the F-150 forum, emphasize the most critical and dangerous step: using a spring compressor. These tools put coil springs under thousands of pounds of tension. If the tool slips, breaks, or is used wrong, the spring can release with explosive force. This can cause serious injury or death. This real risk is the most important factor in your decision.
Essential Tool & Step Overview
This isn’t a complete guide but an overview showing the job’s complexity.
1. Safely lift the vehicle with a jack and secure on jack stands.
2. Remove the wheel.
3. Disconnect sway bar links, brake lines, and ABS sensor wires attached to the strut.
4. Unbolt the bottom of the strut assembly from the steering knuckle.
5. Unbolt the top strut mount nuts in the engine bay or trunk.
6. Carefully remove the entire strut assembly from the vehicle.
7. CRITICAL STEP: Use a quality spring compressor to safely compress the coil spring until tension is off the top mount.
8. Remove the main strut shaft top nut and old mount, then install the new one.
9. Carefully decompress the spring and reassemble everything in reverse order.
10. Get professional wheel alignment immediately after completing the job.
Should You DIY? A Checklist
Use these points to honestly assess your abilities before starting.
Go for DIY if: * You own comprehensive mechanic’s tools, including torque wrenches and deep sockets. * You can rent, borrow, or buy a high-quality, robust spring compressor. * You have a full, uninterrupted day for the project. * You fully understand and are comfortable with spring compression safety risks.
Hire a Pro if: * You lack specialized tools, especially a reliable spring compressor. * You’re not 100% confident in the procedure after watching multiple tutorials. * Your time is more valuable than money saved on labor. * You prefer peace of mind from professional repair and work warranty.
