Diagnosing Leaks, Drift, and Uneven Movement in Hydraulic Cylinders

When hydraulic cylinders start acting up, leaks, drift, or uneven movement are common culprits. I first check seals and rods for any fluid escape, then monitor pressure consistency during operation to spot drift. Uneven extension or retraction often means an internal bypass or air in the system, so I listen for odd noises and feel for jerky motion on each stroke.
