My power steering fluid leaking through subframe in front middle of chevy impala

Steering 'rack' is most likely culprit! .. Recommend having repair shop hoist vehicle to check leak while fluid is under pressure (turning wheels lock to lock) .. They'll know what to do. https://repairpal.com/repair-shops

It was not the rack, it was my return PS line , small connection rubber hose 6inches, pushed it up further over the aluminum return line tube of the PS line, tightened up clamp no more leakage
