External Leakage: Most commonly caused by a damaged rod seal due to a pitted or scratched piston rod (from inadequate cleaning) or fluid contamination.
Internal Leakage (Bypass): Worn piston seals lead to sluggish steering, an inability to hold a straight line under load ("drift"), and the machine feeling like it has "loose" steering.
Bent Piston Rod: Typically caused by a severe impact or misuse.
Worn Trunnion Bushings: Results in excessive play, a "knocking" sensation during steering, and imprecise control.
