What's wrong?
The hydraulic assist steering system on a 2018-2019 Oshkosh S-Series mixer uses pressurized fluid to help turn the front wheels. One hydraulic hose feeds the steering pump, while another feeds auxiliary hydraulic power for the mixer body. Each hose has a specific routing job, even though the hoses look alike.
On affected mixers, the hydraulic hoses were installed in the wrong locations on the rear hard line assembly. The hoses are similar in size and use fittings with the same diameter and thread size, so they were switched during installation. When the auxiliary hydraulic hose is connected where the steering hose belongs, the system can develop hydraulic fluid leaks, affect engine performance, or lose hydraulic steering assist.
There is no warning sign before failure. Owners reported hydraulic fluid pooling under the vehicle, so visible fluid under the mixer is a reason to stop and have the hydraulic hose routing checked.
