Roadside Assistance

While most issues are handled through Preventative Maintenance, there’s no telling what can happen when your fleet vehicles are out on the road. MTR can perform roadside calls for Fleet Services clients when they run into trouble. Typically, MTR can have a service technician out to your vehicle within an hour. MTR’s heavy-duty roadside services include fuel delivery, jumpstarts, lockout services, computer diagnostics, simple mobile repairs and more.

United Axle Spindle Repair

It only takes hundredths of an inch of wear, or a wheel bearing failure on a spindle to render it ruined. MTR Fleet Services uses patented United Axle replacement spindles made with the same high-quality steel as the original OEM spindles. MTRFS technicians are trained in United Axle’s proprietary installation process and tooling which can take place either on-site or in our shop. You will be left with a better, stronger, serviceable spindle at a fraction of the cost of replacing an entire axle.
