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.
