Case Study Summary
This 2008 Toyota Sienna van came to Hoover Street Auto Repair with a broken front suspension spring, a visible lean at the left front corner, and noise from the driver’s side front wheel area when turning or driving over bumps in the road.
Our Toyota technician confirmed the customer's concern during a test drive, inspected the suspension on a hoist, and found a broken left front spring and a leaking right front strut.
We recommended replacing both front strut and spring assemblies as a pair, using quality aftermarket complete assemblies to control cost, and then performing a four-wheel alignment.
After the repair and alignment, the Sienna drove straight with no abnormal noise, ride height was even, and handling was restored to safe, predictable performance.

Customer Concern & Problem Overview
This 2008 Toyota Sienna came in because the owner noticed the van was leaning on the left front corner and making noise in the driver’s side front wheel area when turning or when driving over bumps in the road.
From the customer’s perspective, the vehicle no longer felt stable or comfortable, and the combination of a visible lean and front-end noise raised concerns about safety, especially when hauling passengers.
Broken front springs are uncommon on passenger vehicles, but when they do fail they can cause a loss of ride height, abnormal tire angles, and steering issues that need prompt attention.
How the Problem Was Diagnosed
Our technician that specializes in Toyota vehicles began with a road test, confirming the customer’s report of noise from the left front and a noticeable lean compared with the right side.
With the Sienna on a hoist, the front wheels were removed so the front suspension could be visually inspected for broken springs, leaking shocks or struts, and worn steering components.
The technician found a broken left front suspension spring and observed that the right front strut was leaking, indicating worn internal seals and reduced damping performance.
Because struts and springs work together to control ride height and body motion, the technician evaluated both sides of the axle and recommended addressing them as a pair instead of performing a one-sided, short-term fix.

Repair Solution Provided by Hoover Street Auto Repair
Although this Sienna had less than 100,000 miles on the odometer, the technician strongly recommended replacing struts and springs in axle pairs to maintain balanced ride height, steering, and handling.
We recommended using non-original (aftermarket) complete replacement strut and spring assemblies, which come pre-assembled with a new spring, strut, and upper mount, to save the customer labor cost and still provide reliable performance.
Our ASE-certified Toyota specialist removed and replaced both front strut assemblies, reinstalled the wheels, and torqued the wheel nuts to the factory specifications specified by Toyota.
A four-wheel alignment was then performed to correct any changes in camber, caster, and toe caused by the failed spring and the installation of new struts, and the vehicle was road-tested again to verify that the noise was gone and the Sienna drove straight with normal steering feel.
By replacing both front assemblies and aligning the vehicle, Hoover Street Auto Repair restored proper ride height, eliminated the abnormal noise, and helped protect tire life and suspension components going forward.

The team uses high-quality parts, follows factory-recommended procedures, and pairs suspension repairs with wheel alignments to restore proper ride height, steering feel, and tire wear, all backed by a strong 2-year/24,000-mile warranty on most parts and labor.
Because Hoover Street Auto Repair is a locally owned Napa AutoCare Center that has served Ann Arbor drivers for decades, Honda owners also benefit from clear communication, practical repair recommendations, and the convenience of a central Ann Arbor location serving nearby communities like Ypsilanti, Saline, Dexter, and Pittsfield.
Likely Cause of the Spring Failure
Broken front coil springs are rare on typical passenger vehicles because they are not usually overloaded or constantly driven on extremely rough roads.
Failures are more common on old, high-mileage vehicles or vehicles that see frequent potholes and harsh driving conditions, but in this case this Honda Sienna’s relatively low mileage suggests a defect or isolated weakness in the spring itself. The vehicle could also have hit an exceptionally deep pothole which broke the spring and damaged the strut.
Because the manufacturer’s warranty period had long since expired, the owner needed an efficient, cost-effective repair through an experienced independent shop.
Suspension Repair Tips
Strange new noises—especially clunks, creaks, or pops from the front suspension—should always be investigated promptly because they can signal broken springs, worn struts, or damaged steering components that affect safety.
A quick inspection on a hoist will usually identify any steering and suspension problems before they lead to further damage or uneven tire wear.
Whenever steering or suspension components are replaced or removed during repairs, a wheel alignment should be checked and adjusted to keep the vehicle tracking straight and to prevent premature tire wear.
Cost & Pricing Information
According to RepairPal’s national estimator for suspension shock or strut replacement, typical suspension shock or strut replacement costs for a 2008 Toyota Sienna currently range around a national average of approximately 850 to 1,200 dollars for both front struts, depending on labor rates and the quality of parts selected, with wheel alignment commonly adding about 150 to 200 dollars to the total price.
This means a realistic national range for a job like this—diagnosis, both front strut assemblies, and a wheel alignment—is often in the 1,000 to 1,400 dollar range before taxes and shop fees, with rust, additional worn components (such as sway bar links or strut mounts), and premium Toyota OEM parts pushing costs higher.
RepairPal data cited here is from estimator pages updated through January 27, 2026, and reflects current U.S. national average pricing; actual Hoover Street Auto Repair pricing will depend on inspection findings, condition of the vehicle, the specific parts chosen, and local shop rates and part prices.

Frequently Asked Questions
1. What are the signs that my Toyota Sienna front struts or springs are failing?
Common signs include a visible lean to one corner of the van, clunking or creaking noises from the front when turning or going over bumps, excessive bouncing after bumps, and uneven tire wear.
If you notice the front of the vehicle sitting lower on one side or hear new noises from the wheel area, it is important to have the suspension inspected as soon as possible.
2. Is it safe to drive with a broken front suspension spring?
Driving with a broken spring is not recommended because it can change ride height, alter wheel alignment, and affect how the van steers and responds in emergency situations.
In severe cases, a broken spring can damage the tire or other suspension components, or jam the steering, so the vehicle should be inspected and repaired promptly to keep your family safe.
3. Why do front springs on a Sienna break if they are “rarely” overloaded?
Most passenger-vehicle springs are designed to handle typical loads and road conditions and rarely fail under normal use.
When springs do break on relatively low-mileage vehicles, it is often due to a defect in the spring material, age, corrosion, or impacts with deep potholes or very rough roads.
4. Why does Hoover Street Auto Repair replace front struts and springs in pairs?
Struts and springs work together to control ride height, body motion, and steering response, so replacing only one side can leave the vehicle unbalanced. Springs and struts wear with age and mileage and having a worn and a new strut will cause an imbalance in the suspension and steering.
By replacing both front strut assemblies as a pair, Hoover Street Auto Repair helps ensure consistent ride quality, safe handling, and more even tire wear on both sides of the axle.
5. Do I have to use original Toyota parts for strut replacement?
For a vehicle of this age, quality aftermarket complete strut assemblies are often a smart choice because they typically cost much less than Toyota OEM parts while still delivering excellent, reliable performance.
In this case study, using non-original pre-assembled strut and spring units kept the overall cost down and reduced labor time without sacrificing safety or ride quality.
6. Why is a wheel alignment necessary after front strut replacement?
Anytime major suspension components like struts are replaced, the position and angles of the wheels can change, affecting camber, caster, and toe.
A proper wheel alignment after the repair ensures the Sienna drives straight, the steering wheel is centered, and the tires wear evenly over time.
7. How much does front strut replacement on a Toyota Sienna usually cost?
2026 RepairPal national averages for suspension shock or strut replacement suggest that a complete front strut job with alignment often falls in the 1,000 to 1,400 dollar range, depending on parts quality, labor rates, and any extra worn components found during inspection.
8. How long does this type of repair take?
On most vehicles, replacing both front strut assemblies and performing a four-wheel alignment can be completed in one business day, assuming parts are available and no heavy corrosion or rust is present.
Hoover Street Auto Repair offers same-day service for most repairs and will provide an estimated completion time when you schedule your appointment.
9. What kind of warranty does Hoover Street Auto Repair provide on this repair?
Hoover Street Auto Repair is a Napa AutoCare Center and backs most repairs, including suspension work, with a 2-year/24,000-mile parts and labor warranty.
This warranty is honored at participating Napa AutoCare locations nationwide, giving you peace of mind whether you stay local or travel.
