iv never seen anyone have luck with stop leak. look above steering box to make sure a line is not leaking and making it look like the steering box is leaking
You can try a stop leak additive to seal it but, even if it works, you will need to replace eventually. Be sure to locate the exact area of the leak. May just be a cut hose or line.
