    When I jacked up my 72 Blazer I noticed that I have a lot of play in my front right wheel. I need to put in new ball joints. I have never done this before; how hard is it? What all is involved? Any info is appreciated!

    I did mine about 3 months ago and it was a lot easier than I thought it would be. basically you need a ball joint kit (avaliable for rent at autozone, checker, ect) a couple of big sockets (1-1/8" and 1" I think, you'll have to check for sure) and a spanner wrench. I couldn't get my hands on a spanner, so I did without (I can tell you what you need to know about this if you decide to do it. just e-mail me). over all it is very easy. the instructions in the hayes books are good enough to get you through it if you're still nervous.

    "When I jacked up my 72 Blazer I noticed that I have a lot of play in my front right wheel."

    -I'm assuming that you already ruled out your front right wheel bearing?!?
    That sounds like you're describing a loose or bad wheel bearing... But I also replaced my Ball Joints when I had taken off the hub, rotor and bearings off the spindle, and found that the play was still there in the spindle coming from the ball joints.
    My 2 cents.

    Just did the bearing last year. Maybe 5000 miles on them. Actually, the truck was on a hoist at a brake and muffler shop and the guy showed me the play and told me that it was my ball joint. But I would rather change them then have them do it.

    The big socket you need is a 1 5/16". I think you also need a 1 1/8" but that is more of a standard size.

    I also couldn't find the spanner socket (it is out there but often envolves special order) so I made one out of a deep impact socket. Took me about a hour to get out the die grinder and get it made which is probily less time than you will spend looking for one to buy.
    Also when I did mine the top ball joint just span when I tried to undo the nut so I had to use a drill and chisel to get it off.
