Powersteering leak

Recommended Posts

My ps is leaking quite badly. It's coming from the rack and appears to be around where the shaft from the steering wheel joins the rack and running down the hose that goes to the ps cooler (possibly the one that goes to the pump) hard to tell exactly as can't get to a ramp until next month. But does anyone have ideas what it could be?

I have a RHD but you get the idea

Well obviously check that you don't have a loose connector . . . or that one of the hoses have split

 

But it could possibly that you have hit something that has caused a crack.

 

At least it's not dangerous . . . keep topping the PAS fluid up . . . and the worst that would happen is you lose power assistance (but being a man you'll still be able to steer the car - once upon a time no cars had PAS, even heavy cars like Mk2 jags!)

Remember the hoses/lines from the pump to the rack are at extremely high pressure . . . so the slightest flaw will cause a leak

 

The return hoses from the rack to the PAS reservoir are quite low pressure, and less of a problem.

There are cheaper options . . .

 

Personally I fitted a good s/h one (which I think came from Chris Wilson!) - just made sure before fitting I cleaned and painted the metal sections to stop any corrosion.

 

Driftmotion (in the USA) do a flexible braided PAS hose fairly cheap (although you need to tell them it's for a RHD car)

 

Or you could have one made up at any local hydraulic hose place - you'd just need to take your old one along so they could see what the fittings are. (would probably charge £40 - 50)
