Brake Drum / Rotor Resurfacing
A brake drum/rotor is not meant to last forever. They wear down a little every time you step on the brake pedal. Most modern cars come with thinner rotors to save on weight. Due to their slimness, the rotors wear out faster. For this reason, it is advisable to have the rotors and brake drums resurfaced every time you are replacing the brake pads. Resurfacing is an economical alternative to replacing the rotors/drums with new ones. If your brake rotors/drums have sufficient metal remaining with no hard spots, cracks, severe grooving, or rusting, then resurfacing is a great option. For expert resurfacing services, call 641-423-1310 or visit Jeffrey Auto Repair Service today.

Press U Joints
A clunking or clicking sound from underneath your car may indicate a worn out universal joint (U joint). A worn U joint can be replaced easily by use of a press machine. First press one side, remove the cap and then press the other side in the same fashion. Although easy, most auto shops do not press U joints due to lack of the necessary machinery and expertise. At Jeffrey Auto Repair Service's machine shop, we have the necessary press machines and qualified staff to press your car's U joints.

Press Wheel Bearings
At Jeffrey Auto Repair Service's machine shop, we will handle all your wheel bearing needs with our high-tech press machines. Call us at 641-423-1310 or visit us in Mason City, IA 50401-5632 today.

Valve Jobs
A valve job is an operation performed on any 4-stroke engine. The main purpose of this job is to resurface the mating surfaces of the poppet valves and their respective valve seats. Valve jobs usually only occur in high-performance vehicles, but sometimes passenger cars need valve jobs for these reasons: overheating, material failure, high mileage, excessive RPM, and foreign object damage. Call 641-423-1310 or visit Jeffrey Auto Repair Service for all your valve job needs.

    What Our Customers Are Saying

    Excellent service, professional and friendly staff. Knowledgeable techs and gear guys. Respectful and thorough. Thanks for getting our vehicle back on track!


    -Kip & Joan

    The staff at Jeffrey Auto Repair were very professional and explained what repairs my auto needed. I would recommend them to anyone. The building and grounds are very clean and neat. They know how to treat their customers.


    -Dolores K.

    I would highly recommend you guys. You were courteous throughout the six weeks you had the vehicle. You made a ton of repairs including the transmission and radiator. But that is not all. I felt as though I had an honest advocate working for me that thought as much of my vehicle as I did. I continued to get options on things that SHOULD be done to keep it running good and things that WILL need fixing in the future. You did not suggest I do everything and that shows your honesty. I feel very confident in the repairs. You even tried a less expensive solution to fix the transmission. Thank you. In the end, I needed the transmission, though, and you had options for me. But all along the way you explained what was wrong and gave me options when there were some. You even went above and beyond and cleaned up the Suburban before I picked it up. I can honestly say no one else has repaired my cars since moving to Mason City 9 years ago. In fact you fixe! d my F-150 when the Ford dealer was unable to do so for 2 years! I have no need to find anyone else to work on my cars. Feel free to share this with any customer. You can even use me for a reference.


    -Randal

    It was great to have the charges actually be around $30 less than the estimate. Very pleased with all the work you have done for us on each vehicle we have owned over the years.


    -Melvin A.

    I called at the last minute and made changes to the work I wanted completed on the vehicle. Brian and his mechanics were very accommodating and completed the work before the time the vehicle was promised. I always feel completely comfortable leaving our vehicles for service because I am confident the work will be completed professionally and correctly. Jeffrey's services our vehicles like they are their own. Thank you.


    -Linda M.

    We've been going to Brian (Jeffrey Repair Service) since we moved into the area in 2012. We found him on accident, but have come to realize that we are extremely lucky in that!! Since then, we have had 5 different cars and he (and his staff) have been amazing on the work with each one of them!!
