Front struts generally require replacing the entire strut assembly and the wear items that come with it. The core replacement is the strut unit itself, along with the top mount/bearing, dust boot, bump stop, and any accompanying hardware. You may also replace the coil spring if it’s part of the assembly, and check or replace stabilizer (sway) bar links if they're worn. After service, a wheel alignment is essential.
In detail, the front suspension uses a combination of damping components and springs that work with steering and tires. Replacing front struts is a good opportunity to service related parts so the system remains balanced, predictable, and safe. The following guidance covers what to replace and what to inspect to avoid returning to the shop soon with the same issues.
What to replace with front struts
Before you replace, assess these components and replace them if worn or damaged. Replacing these items together helps ensure proper damping, noise suppression, and alignment over the life of the new struts.
- Front strut assemblies (complete units or cartridges, depending on your vehicle and the repair method)
- Strut top mounts (top hats) and the bearing, if there is play or noise
- Dust boots and bump stops to seal the piston rod and cushion travel
- Coil springs (if the existing springs are fatigued, cracked, or sagging; many replacement kits include springs or require reusing springs with caution)
- New mounting hardware (bolts, nuts, and washers; many items are one-time use and require replacement for proper torque)
- Sway bar (stabilizer) links, if worn or damaged
After you install the new struts, have the alignment checked and adjusted as needed. This step helps prevent uneven tire wear and preserves steering feel.
Additional checks and related considerations
Replacing front struts is a good time to inspect other parts of the front suspension and steering for wear or damage. The following items are commonly checked or replaced as warranted.
- Tires and wheel balance; replace if worn or cupped to avoid imbalanced handling
- Brake components near the strut such as pads, rotors, and calipers if wear is evident or if you’ve opened the brake system in the process
- Tie rods and inner/outer steering joints for play or looseness
- Ball joints and control arm bushings for deflection or noise
- CV joints and axle shafts for boot damage or clicking noises
- Wheel bearings for play or rough movement
- Other worn bushings and mounts in the front subframe that can affect alignment and ride quality
Comprehensive replacement and inspection can extend the life of the suspension and improve safety, but it also increases cost and complexity. Consult your vehicle’s service manual or a trusted technician for model-specific guidance.
Summary
When replacing front struts, replace the strut assembly and associated wear items such as the top mount, bearing, dust boot, bump stop, and mounting hardware; replace the coil springs if fatigued; consider new stabilizer links; and have the alignment checked afterward. Also inspect related components like tires, brakes, tie rods, ball joints, and wheel bearings for wear and replace as needed. A properly installed, well-aligned front suspension improves ride quality, handling, and safety.
When replacing struts, what else should I replace?
If you are replacing a strut on a vehicle, you need to inspect the sway bar links and look up if there are cam bolts that can make camber adjustable. The sway bar links will make sure the suspension is silent after the strut is replaced and they probably need replacement due to wear.

Do I need to replace both shocks and struts at the same time?
While you might think that you're saving money by only changing the shock or strut that is showing signs of failure, don't be tempted to compromise. There are many reasons why replacing both shocks and struts on an axle is the right choice for ensuring the ride and handling of your vehicle.

What happens if I drive with bad struts?
Reduced braking efficiency – Worn shocks and struts can have an adverse effect on the performance of your brakes. Your vehicle's stopping distance may increase, which can be critical in an emergency braking situation. You're also at increased risk of skidding on wet roads.

What should be performed after struts have been replaced?
Monroe ® recommends performing an alignment anytime struts or other steering and suspension components are replaced. Failure to make sure the vehicle's alignment is within factory specifications can lead to problems like premature tire wear and other customer comebacks.
