Small leak where the p.s. hose connects to the power steering pum

Check the O'ring for not being cut. When ok and fastening the nut doesn't help, you will need a new hose.

Possibly a bad P.S. hose, or maybe a loose hose connection. Close inspection is the only way to find the leak.

That body style of Grand Cherokee usually developed a leaking lower steering gearbox seal. The seal alone can be replaced to stop the fluid leak. As to why 'park does not work' I don't fully understand that question.

Many times if it's a small leak, a good product such as Lucas steering sealer will help. Don't expect the leak to stop immediately though as the seals take time to swell. If the leak is from a hose, the only way to fix it is by replacement. There is a lot of pressure in there and anything else will not work.
If the seal leak is large, additive may slow it down but that too would need replacement.

Hi
Sounds like it is the hose from the power steering pump to the stearing unit , look at the airea of the leak and have some one steer the wheel running to see where it is coming from

If it is leaking out of the hose, replace the hose

For the Power Steering Pump, refer to the 1995 ZJ Service Manual (Section-19-Steering / page 9 and next)

Hope helped with this (remember rated this help) Good luck.

I had the same problem. You can not replace that o ring. You have to replace the complete hose ***. They redesigned the hose to fix that common problem. To bad the customer has to pay to replace a poorly designed part.

Just a heads up, $10 bucks will buy you a seal kit for the P.S. pump. I topped mine off for a couple months, then the oring on the high pressure line (from pump, front center) blew and dumped the reservoir in a matter of miles.

The line can be a stinker to get off, recommend driving the car for a few minutes to heat up the pump a little. Don't forget the 20MM wrench.
