I travel the world as a leadership consultant and give talks to various business leaders on how to treat people right- Ralph from Mobile Truck Repair will now be a highlighted person in my talks. As I was in the midst of a solo road-trip with the ashes of my late father to honour his wishes, I found myself on the side of the road in unknown territory in rain, wind, and nightfall approaching. To say I was completely terrified is a huge understatement! Ralph not only communicated quickly that he was on his way to help, he was incredibly thorough in ensuring my safety on the rest of my journey. Did I mention the cold and the rain?! THIS is the customer service and quality that all business leaders should aspire to. Ralph not only restored my tire but he restored my conviction that strangers can do right by each other in business. I hope he gains immense success and kindness in his business. We need far more like him!

Blew a coolant line as I was pulling into a customer in Le Mars, Ralph came and got us all fixed up, and it was about 7:30 pm when my dispatch got to him and he showed right up. He checked over his own work thoroughly and didn't leave till truck was operating as it should! Thanks Ralph, you are very much appreciated!

These guys were amazing! I am traveling back to the west coast and have had quite a month in our Bluebird bus. We’ve had it looked at 4 times between Indiana and Iowa. We were having squeak and screech issues that were supposed to be fixed in Des Moines. Low and behold, four days later, the same problem came back with a vengeance. I called Mobile Truck repair when we got to Sioux City and they were amazing. Ralph pretty much diagnosed the problem on the phone, and he and John cam out and fixed the issue in a timely manner. I was amazingly surprised when they didn’t charge us because of another shops screw up( 3 missing bolts). They were super nice and super knowledgeable. Hopefully I never have to, but I will for sure call them again if we are having automotive troubles in the SiouxCity area! Thank you guys so much!!

Truck repair
Diagnostic and repair service for all make and model trucks, trailers, and heavy equipment

Fuel delivery 
Sometimes it happens. I’ve done it myself. As luck has it if we bring you fuel you pay the same price as the pump. 

Fuel tank repair
Refer trailers all over are showing signs of age. We have developed a state of the art method for patching aluminum tanks. Very cost effective and saves hours of preparation. Best part is we know it will last

Low power, no power, hard start, no start, white smoke, any fuel related issue

Driveline replacement and repair, ujoints hanger bearings, yokes, axle shafts and more

Springs, airbags, shocks, spring hangers, equalizers, ride control issues on every make and model trucks or trailers

Steering gearbox replacement, draglink, towbars on steer axles and pushers. Spindle and hub replacement, seal and bearing replacement.

Truck won’t regen? We’re Troubleshooting with the correct oem software to diagnose issues where ever they are. No matter if it’s a Turbo not building boost, an exhaust needs cleaned out, sensors not relaying messages to the ecm, maybe just have an oil or coolant leak someplace obvious.

Love spending loads of cash at a dealership having an electrical issue tracked down? Didn’t think so. Give us a call. What ever electrical problem you have is no problem at all. Engine or chassis, abs, lights, ecm, automatic transmission, switches in dash, something not right?

Check engine light on? Automatic Transmission won’t shift, truck won’t start, limp mode slowing you down? With oem software for every truck in the road we can diagnose the problem without the wait and without the outrageous price.

Air brakes
Brake chambers, slack adjusters, air lines, pads, shoes, drums, rotors, brake valves

Abs light on in the cab or at the back of the trailer? We can tell you why and assist you with the correct repairs the first time. Take the guess work out of what sensor or valve is giving you trouble call before you get to the scale

Heavy truck repair
Anything you need repaired or replaced on your truck.

Trailer repair
Lights, airlines, brakes, wheel bearings, hubs, seals, gladhands, airbags, dolly legs, landing gears, dot bumper, mudflap, if it’s not listed it’s because I know you get it by now. It’s busted or missing we will fix or Replace

Jump start
A jump start is all. I would hate to see the bill if you called anyone else. 

Forced regen
If your not having any luck with the dash button you should double check the engine brake is off. If that don’t help we might be able to get you going over the phone. If not we have a computer packed with software to get you back in the action

Refer unit repair
They pretty much fix themselves but we will help
Gelled up fuel

Clutch adjustment

Battery replacement
There is a difference between a bad battery and a dead battery. Did you know you cannot load test a dead battery. Also a bad battery can still have more then 12 volts. We will help you decide if your batteries need replaced. 

Starter replacement
Trucks get starters replaced all the time because the guy showing up with tools calls himself a mechanic.  9 out of 10 starters are still good and easily fixed. That saves the owner hundreds In parts and labor.
