How to install pressurized power steering hose

  • 4.8L

My car was just spewing power steering fluid, and I figured out that there was an issue with the pressurized hose. I got a replacement hose, but I cannot find anywhere that will teach me how to replace it. I am hoping someone can help me.
Do you
have the same problem?

There are no instructions online because it is a very basic job. The issues are winding the hose through tight places and screwing the fittings together without cross-threading them.

One trick is to tie a piece of string or wire to the end of the old hose so when you remove it, you pull the string through where the hose was. Tie the string to the new hose and pull it back through to where it gets connected. That insures the new hose is routed correctly to avoid obstructions and so it wont rub against something that could transmit the buzzing noise of the pump into the passenger compartment.

When you screw in the line nuts, always turn them in at least two or three turns by hand before using a wrench to be sure they are not cross-threaded. Those nuts are very soft metal, and the rack and pinion steering gear housing is made of aluminum. The threads on either of those can be damaged very easily by cross-threading. Tip the metal tube of the hose in various directions if the nut does not start right away.

Use a flare-nut wrench, aka line wrench, on those nuts. A regular open end wrench will round off those nuts. Be sure there is a rubber o-ring on each end of the new hose. On some hoses like this one the metal ends might be able to swivel and may feel loose when the nuts are tight. The o-rings do the sealing so it is okay if hose swivels.
