Rebuilding the steering box..
As soon as I swaped in the 7.4l Vortec in my truck my steering box started leaking. I kinda have a theory but not sure- I used the powersteering pump from the 7.4l motor which was had a hydroboost setup. I have read that the hydroboost powersteering pumps have more pressure and thats what caused the leak...
But on the flip side- I did just swap in the front suspension clip from a 1979 5/8's ton truck with included this steering box, it could have had the leak before.. So does the powersteering pump from a hydroboost system have more pressure? It only leaks when I shut it off, but it leaks alot out. I have never rebuilt a steering box before, are they pretty simple? And if I did rebuild it- replace a seal or whatever is causing it to leak.... will it leak again because of the powersteering pump???? Thanks---- |

Re: Rebuilding the steering box..
They are not hard to put seals in. If it needs a comeplete o-haul I just get a reman. Find out which seal is leaking. It could be the upper, called the worm shaft seal or the lower called the sector shaft seal. The seals are available separatly or a complete kit. Get a service manual or let us know which one you want to replace & someone on the website will give blow by blow directions.

Re: Rebuilding the steering box..
The higher pressure (if it actually is) will not hurt it. GM built millions with Hydroboost & PS. The only time the pump reaches max pressure is when you turn hard to one side against the stops, which you shouldn't do. Thats why it labors, slows down the engine & squeals the belt.
