What Our Santa Rosa Customers Say
My truck was pulling so bad I couldn’t drive safely. On-Site found a worn tie rod end and had me back on the road the same day. Professional work at a fair price.
– Robert M., Bennett Valley
Hit a huge pothole near downtown and my car started making noise. They diagnosed a damaged strut and fixed it quickly. Great service when I really needed it.
– Jennifer K., Railroad Squar
Been getting my alignment done here for years. They always take time to explain what they’re adjusting and why. My tires last much longer now.
– Carlos R., Fountaingrove
Frequently Asked Questions About Steering & Suspension
Steering and suspension systems are essential for safe, smooth driving and vehicle control. Many Santa Rosa drivers ask about common issues like uneven tire wear, strange noises, or poor handling. At On-Site Auto Repair, we provide expert diagnostics and repairs to keep your suspension system in top shape.
How often should I get a wheel alignment in Santa Rosa?
We recommend alignment checks annually or every 12,000 miles. Santa Rosa's hills and varied road conditions can affect alignment more frequently than flat terrain.
What causes my vehicle to pull to one side while driving?
Common causes include misaligned wheels, uneven tire pressure, worn suspension components, or brake issues. We can diagnose the exact cause quickly.
How do I know if my shocks or struts need replacement?
Signs include excessive bouncing, rough ride quality, nose-diving when braking, and uneven tire wear. Most shocks/struts need replacement around 50,000-100,000 miles.
Can you align my lowered or modified vehicle?
Yes! We have experience with modified vehicles and can provide proper alignment for lowered cars, lifted trucks, and performance vehicles.
Will steering problems affect my safety?
Absolutely. Steering issues can cause loss of vehicle control, especially in emergency situations. Don't delay repairs on steering-related problems.
How much does steering and suspension repair typically cost?
Costs vary widely depending on the problem. Simple alignments start at $89, while major suspension repairs can range from $200-1000+. We always provide estimates before work.
Do you warranty your steering and suspension work?
Yes! We provide warranties on parts and labor for steering and suspension repairs. Specific warranty terms depend on the service performed.

On Site Auto Repair in Santa Rosa is a full service auto mechanic shop. Our auto mechanics are certified and are here to help with all of your repair needs. No auto repair job is too big or too small for On Site Auto Repair. We handle all types of auto repair, including regular maintenance, engine repair, brake work, and troubleshooting.

Vehicles are usually described as 5 speed or 6 speed, meaning they have that many gear ratios. Those gears let the vehicle travel across the full range of speeds and use the engine's power efficiently. Transmissions are complex and are in constant use, so they take a lot of wear and tear. Many owners also forget to check and change the fluid on a regular schedule. That is why transmission problems are so common. At On Site Auto Repair in Santa Rosa, our transmission technicians can diagnose, repair, or replace your transmission. If you are looking for an honest transmission repair shop, give us a call today.
There are several warning signs that your vehicle can give you before your brakes may reach the point of potential failure or extensive repair. Whether composed of ceramic, semi-metallic, or organic materials, brake pads erode each time you depress the brake pedal. If the pads wear down too much without being replaced, the metal housing for the pads will make contact with the metal rotors (or drums), which may produce not only a safety issue but a situation where the rotors/drums are required to be replaced as a result of the prolonged contact of metal parts without the pad buffer. If you are in need of an affordable brake repair mechanic in Santa Rosa, please do not hesitate to schedule an appointment today!
Vehicle Inspection In Santa Rosa
The key to top notch automotive repair and troubleshooting lies in a thorough understanding of what’s actually going on under the hood. Sure, you know that a radiator keeps your engine cool, but understanding how it keeps it cool is the key to solving technical problems efficiently. If you know which parts perform what function, your powers of diagnosis will be much more powerful.
Radiator Inspection Service In Santa Rosa
Ensuring that your vehicle’s engine cooling system is in proper operating condition is extremely essential to engine life and performance. Operating at excessive temperatures can lead to premature engine wear. Your vehicle’s engine cooling system should be checked periodically, and a radiator coolant flush is also recommended to prohibit radiator corrosion. On Site Auto Repair will thoroughly drain and power flush the old coolant and particulates, and refill the cooling system with your vehicle manufacturer’s recommended coolant.

Auto Repair Services We Offer in Santa Rosa, CA
Our shop at 363 W 9th St B & C handles a wide range of repairs and maintenance for drivers across Santa Rosa and Sonoma County.
Engine Diagnostics and Check Engine Light
A check engine light means your car is reporting a fault. We connect an OBD-II scanner, read the fault codes, and explain what they mean in plain language. We diagnose the problem first, then tell you what the repair will cost.
Oil Change Service
We do full-synthetic and conventional oil changes. We use the viscosity grade your manufacturer specifies, such as 5W-30, 5W-20, or 0W-20, and we replace the oil filter every time.
Brake Repair and Replacement
Worn brake pads squeak. Worn rotors grind. A soft brake pedal is a warning. We inspect and replace brake pads, rotors, and calipers using OEM-quality and aftermarket parts, depending on your budget.
Battery, Alternator, and Starter Repair
We test your battery with a load tester, not just a voltage check. We also test the alternator and starter, because a failing alternator will kill a new battery quickly.
AC and Heating Repair
If your AC is not blowing cold, we recharge the refrigerant and check for leaks. If your heat is not working, we diagnose the cause and repair it.
Scheduled Maintenance and Tune-Ups
We handle spark plug replacement, belt inspection and replacement, air and cabin filter replacement, fuel system service, coolant flushes, and transmission fluid service. If you are not sure what your car is due for, we look it up by make, model, and mileage.
Tire Rotation and Inspection
Uneven tire wear affects handling, fuel economy, and tire life. We rotate your tires, measure tread depth, inspect the sidewalls, and check the pressure.
Pre-Purchase Inspection
Thinking about buying a used car? We check the brakes, belts, fluids, undercarriage, and suspension, and we run a diagnostic scan for hidden fault codes. Call for current pricing.
