You hit a road bump, and suddenly, there’s a clunk.
Soon after, the rear of your car starts to feel unstable and uneven.
If this sounds familiar, your trailing arm might be damaged. This suspension component plays a big role in your vehicle’s stability. When it wears out, it compromises safety and handling.
Don’t wait for a suspension failure to catch you off guard — get it repaired ASAP.

How Much Does a Trailing Arm Replacement Cost?
Here’s a breakdown of the total cost:
A. Range
The average cost of a trailing arm replacement is between $430 and $920.
This includes:
- Parts cost: $260 to $700
- Labor cost: $170 and $220
B. Factors Affecting Cost
The following factors can influence the total trailing arm replacement cost:
- Vehicle make and model: Luxury and performance cars have expensive parts and higher labor costs due to complex suspension systems (that require additional handling hours).
- Location: Labor costs also vary by region. Mechanics in urban or high-cost areas typically charge more than those in smaller towns or rural areas.
- Original Equipment Manufacturer (OEM) or aftermarket parts: Choosing OEM parts usually means better fit and reliable performance, but they come at a higher price. Aftermarket parts are typically more affordable, though they may not offer the same level of durability or quality.
- Related repairs: Replacing a trailing arm may uncover a worn bushing. A trailing arm bushing replacement will cost you an additional $50 to $110.
- Number of trailing arms: It’s best to replace the trailing arms in pairs, because if one side is worn, the other is likely close to failing. While this increases the overall cost, it helps maintain balanced handling and suspension performance.
Is It Worth Replacing a Trailing Arm?
Yes, definitely.
A damaged rear trailing arm can lead to poor handling, uneven tire wear, and uncomfortable vibrations. Left unchecked, it can further damage your car’s suspension parts.
A timely trailing arm replacement helps maintain your car’s stability, comfort, and safety on the road.
If you suspect a faulty trailing arm, contact your trusted mechanic or an auto repair shop immediately.
NOTE: It’s a good idea to have your control arms and control arm bushings inspected when you’re replacing the trailing arms. Like trailing arms, a faulty control arm in the front suspension can affect your vehicle’s alignment, handling, and tire wear. A control arm replacement typically costs between $670 and $760, while replacing control arm bushings will cost you $200 to $420.
4 Pressing Signs You Need a Trailing Arm Replacement
Here are some symptoms that your trailing arms are failing:
- Clunking noises from the rear: If you hear clunking sounds from the back of your vehicle — especially when going over bumps, braking, accelerating, or turning — it could be a failing trailing arm.
- Vehicle pulls or sways while driving: Worn trailing arm bushings or a broken trailing arm can cause the rear axle to move independently of the vehicle’s frame. This can cause your car to pull to one side or sway, making it hard to drive in a straight line.
- Rapid and uneven tire wear: A faulty trailing arm can throw your suspension out of alignment, causing the vehicle’s weight to shift unevenly. This often leads to abnormal or premature wear on your rear tires.
- Uneven vehicle height: If one side of your vehicle appears higher or lower than the other, it could indicate a suspension component issue. In some cases, worn trailing arm bushings can affect the height by changing how the rear springs sit.
How Is a Trailing Arm Replaced?
Replacing a rear trailing arm requires you to lift the vehicle, support the suspension parts safely, and apply precise torque specifications. That’s why it is wise to consult a professional and not attempt a DIY repair. Improper installation can affect your vehicle’s safety, alignment, and handling.
But if you still wish to know, here’s how a professional will proceed. They’ll:
- Raise the vehicle using a jack or lift kit and secure it on stands to access the trailing arm and surrounding suspension components.
- Support the axle that connects to the trailing arm separately. This helps relieve any pressure on the arm and keeps it in a neutral position during the replacement.
- Loosen and remove the bolts from each trailing arm’s mounting points, then remove the damaged part.
- Fit the new trailing arm in position, ensuring it’s properly aligned.
- Tighten all mounting bolts using a torque wrench, following the manufacturer’s recommended torque specifications.
- Remove the support from the axle, set it back into place, and lower the vehicle.
- Take the vehicle for a test drive to confirm that the suspension performs smoothly.
How Long Does a Trailing Arm Last?
A trailing arm typically lasts between 90,000 and 100,000 miles under normal driving conditions.
Manufacturers build them to be strong and durable, so the metal arm rarely wears out. However, the rubber bushings tend to wear down faster and may need replacement earlier.
