    Steering Gearbox leakin on \'73

    I have a pretty good power steering leak in the top seal (where the steering column comes in) on my 73. Should I take it apart, never did it before, or replace it. What years steering gear will fit and from what vehicles? I can check out the junkyards around Houston or go to dealer, any idea how much $$$

    hahahah, sorry not laughing at your post! I had this exsact same issue last week.
    Yes you can replace that seal and hope it works but this was my thought.
    My rig is a 72 so thats what 29yrs old, well my steering box 'looks' that old so instead of repairing it I decided to retire the box from service and get a new/rebuilt one from Napa. So 170 bucks later I now have a new gear box and my steering is KILLER!! Way smother than it has ever been!! Very glad I droped the extra cash on a new box instead of trying to rebuild the one I had or getting a dry one from the junkyard!

    The seal is like $5 from Auto Ztoned. Take the box off the truck. CAREFULY drill 2 holes 180 out into the seal. BE VERY CAREFUL not to nick the shaft or the housing. The holes will let you colapse the seal and pry it out with an awl. This way you don't have to take the box appart. Clean the shavings from drilling with some brake cleaner (huld the box with that seal down). Tap a new seal in with a deep well socket and your good to go for another 25 years.
    I'll be doing a box rebuild tech artical soon. I'm swaping my box on my 75 to a 79 close ratio. Got the box but need to get the rebuild kit.

    It's not my damn planet monkey boy!

    Thanks, Grim do you mean drill holes 180 degrees apart and how big should the holes be? Is there any advantage to a new box do you think? will it tighten up the steering alot?
