In a message dated 98-06-13 00:20:26 EDT, you write: << power steering unit leaks Does anyone have any experience replacing the main power steering unit? My '57 DeSoto Firedome has a leak in the upper unit. Right now the fluid is leaking out of the vent hole in the upper housing, indication an internal leak. What about just plugging off the vent hole so the fluid doesn't leak out? >> I dont know what the unit looks like, when U say leakig out upper housing VENT HOLE vent holes are usually above the fluid level to bleed off excess pressure or fluid. If U have fluid coming out a VENT HOLE it means U have a problem, perhaps with foaming caused by a mechanical malfunction??? Plug the hole????????? If we were age 16 and this was our first car we might plug the hole. Being older and wiser today we realize the hole is there for a reason and know fluid coming out means we have to diagnose the problem. Anyone able to volunteer a shop manual?????? Or a Motors manual that covers the '57? (just dont copy it, tho U may be able to copy the part dealing with only power steering malfunction for personal use..?) Rotsa Ruck Lars My 61 Motors manual shows t3 views of the unit. Unable to find the vent but U R talking vent on the master cylinder not on the power unit? If so sounds like a lot of pressure is being built up where it is not supposed to be? Time a new unit???
