4X4 SERVICES

The technicians at Jeffrey Auto Repair Service have years of experience working on standard 4-wheel drive (4x4) vehicles as well as all-wheel drive (AWD) vehicles. AWD is a full-time 4-wheel-drive system (all four wheels receive torque from the engine simultaneously) that employs a center differential that allows each tire to rotate at different speeds.

We understand the special needs of these vehicles. These are some of the services we offer.


Transmissions
Transmission repair is not something to take lightly. The transmission is connected to key parts of your vehicle and needs to be working properly for your safety. Transmission services include replacing filters and draining fluids to prevent transmission damage. Typical transmission issues that may lead to repair may include shifting issues, slipping, stalling, fluid leaking, and the service light turning on. If you are concerned that you may need transmission repair, don't hesitate to schedule an appointment at Jeffrey Auto Repair Service today.

Transfer Cases
A transfer case is a part of a four wheel drive system found in four wheel drive and all wheel drive vehicles. The transfer case receives power from the transmission and sends it to both the front and rear axles. This can be done with a set of gears, but the majority of transfer cases manufactured today are chain driven. The transfer case is connected to the transmission and also to the front and rear axles by means of drive shafts. Trust the automotive experts at Jeffrey Auto Repair Service for all your transmission repairs.

Differentials
The differential transfers the engine power to the wheels. One important function of the differential is to pass on power to the wheels while allowing them to rotate at different speeds - thus the name differential. When turning, the outer wheels travel a larger distance than the inner wheels do (also the front wheels travel a longer distance than the rear wheels). This means that all four wheels travel at different speeds during a turn and this is where the differential comes in to help. To make sure your vehicle's differentials are working properly, have them checked regularly. Contact Jeffrey Auto Repair Service today for differentials examination and servicing.

Driveline
A driveline is a part of your motor vehicle that connects the engine and the transmission to the wheel axles. The driveline consists of the parts of the powertrain less the engine and transmission. Failure of the driveline means that the car would not move since energy cannot be transmitted from the engine to the wheel axles. Therefore, make sure that your car's driveline is regularly inspected and serviced. And, at Jeffrey Auto Repair Service, you can have the driveline serviced by experts.

Alignment
Wheel alignment (or simply alignment) is standard car maintenance that involves adjusting the angles of the wheels so that they are set to the manufacturer's specifications. The main purpose is to let the suspension and the steering systems operate at their desired angles - this reduces tire wear. Alignment is a complicated process and not all mechanics get it right. To have experts handle your car's alignment, visit Jeffrey Auto Repair Service.

Wheel Bearings
Wheel bearings are found inside of wheels, allowing the wheels to spin freely, and are connected to the brake system. They can become worn over time, causing a vibrating suspension and noisy rubbing as the car is driven. If they break completely, the vehicle will become very difficult to control and unsafe to drive. Replacement interval for wheel bearings varies greatly, but they should be checked for leaks and wear periodically. Jeffrey Auto Repair Service can make sure that your bearings are in good shape and let you know if they need replacement.

Hubs, Seals, Studs, & Nuts
A wheel hub motor, also referred to as a wheel motor, is an electric motor incorporated into the wheel hub and drives it directly. You can have a safer and smoother ride today by replacing your warped and worn out wheel hubs. Let Jeffrey Auto Repair Service replace your worn out hubs today.

Properly working seals provide oil and grease sealing - offering enhanced performance in a wide range of temperatures and environments. Worn out or warped seals allow external contaminants to enter the bearing unit or let lubricant escape from the unit. This ultimately leads to premature failure of the bearing unit. To keep out contamination and retain lubricant in the bearings, have the seals replaced with new ones. To have the seals replaced by experts, contact or visit Jeffrey Auto Repair Service today.

Studs are the threaded fasteners that hold on the wheels of your truck. The wheel studs are permanently mounted on the wheel hub through the brake disk or brake drum. To secure the wheel, nuts (lug nuts) are fastened over the stud. Stripped wheel studs can be quite dangerous. Damaged wheel studs should be replaced with new ones immediately. To have your truck's wheel studs replaced with high quality ones, call 641-423-1310 or visit Jeffrey Auto Repair Service today.

A wheel nut or lug nut is a fastener for securing a wheel on the hub. A set of lug nuts are used to secure a wheel to the threaded wheel studs (which are fixed to a wheel hub). Worn out nuts means one thing - the wheel is not fixed securely on the vehicle which puts the vehicle at the risk of rolling over. To have your truck's wheels securely fastened to the hub, contact or visit Jeffrey Auto Repair Service in Mason City, IA 50401-5632 today.


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!!
