small leak at steering box

small leak at steering box

Postby Coaster [OP] » March 4th 2020, 4:39pm

i am leaving a pudddle everywhere i park and it appears to be at the hose connections at the steering box. the hoses are a year old almost to the day. the box is two years old.

i have had a lot of power steering issues in terms of blowing hoses every year for 7 years, this winter i made it through probably due to using synthetic fluid (its very cold here).

at this point i dont know if the leak is from the fitting or the crimp a the end of the hose, but i do know the ends are quite snug in the steering box but not "cranked down" like on a 1970 style.

this is a new kind of leak for me, usually the hoses just explode in the middle. i'm not sure why i have such issues with the steering system but its better with the synthetic.

any insight? can i get new rubber seals or should i just replace all the hoses?

You will have to find out if it's the fitting or the crimp. Should be able to simply replace the o-ring if it's the fitting.

source of leak is the fitting on the power side inlet of the steering box hose from the booster. its dripping out between the tube and the nut. i tried tightening it a little but no change.

i got 17 months out of this hose, longest yet. i switched to synthetic last march. i am sure the o ring is bad although i dont know why. hose is in great shape but if i am going to pull it off the steering box i am just going t replace it.

i bought a new delco hose from rock auto, hopefully can drip along till friday or saturday then pull the shroud out so i can get to it.

am i overtightening these or something? i have read 25# but i just have to guess. i did the last set of hoses just snug, no excess tightening and the other connections are ok. usually the hose blows in the middle so this is new.

I've never had a connector leak.
You may become the new "expert" on this one.
I imagine the crimp can leak too.
New hose.. make it tight, but not too tight.

I remember that conversation, glad the switch to synthetic helped. Check for burrs or something before installing that new one. Fingers crossed that this will be your final hose.

i got the hose off in minutes , took longer to install the new one.

closely inspected the green o rings and the hydroboost side was compressed/deformed evenly all the way around. this side did not leak. the steering box o ring, where it leaked out between the threaded connector and pipe was NOT evenly compressed/deformed all the way around. i couldnt see anything that would cause a leak but obviously it leaked.

i was very careful to hold the pipe in the correct position when i tightened the nut at the steering box. i tightened it until when i let go of the pipe it would not rotate on its own and stayed where it was.

so far i dont see anything coming out when i watch it (it would drip, drip, drip, drip before) but i am still leaving some fluid spots when i park it. not like before, i hope its just leftover fluid dripping off the box (there is a bit).

may pressure wash it soon in there

13 months later and i just ordered 2 hoses from rock auto again. been dripping a while and it got fast last week. $25 of amsoil in my parking spot.

i'm begining to wonder if the 2" body lift is having an affect on the hose life. this whole steering nonsense is getting old.

I have at least 7" body lift, and I'm using the stock original hoses.
I did a post a while back about rerouting through the hydroboost.. but the need wouldn't likely apply to 2"

We've ALL replaced leaking PS hoses!
It's common.
