power steering cylinder leaking

OK, I noticed a small drip under the vert the other day, was not to worried as it seams to come and go...size of a half dollar, and thought it would be something to deal with after summer/fall driving season. This morning i noticed a big puddle, and the pump resevoir was real low! Seames to be seaping from where the piston rod goes into the cylinder...maybe a bad seal? Anyway is there a way to re seal or is it time for a new cylinder? Does not look like it is a big deal to replace, and I dont know if it changes things like allignment ( i doubt it) but would like advise from someone more experianced!  THANKS FOR THE HELP!!!

You can get a rebuild kit for it, pretty easy if you follow directions. It will leak again down the road, if your not hung up on all original you might look into changing to rack & pinion steering.

I went the kit route recently and it was not difficult (very inexpensive fix).  The ram is easier to do than the power valve, but sounds like your valve is okay.  Pay close attention to the instructions in the kit. 

Great tip Tom and thanks for the post!

 Eric.. I had the same problem in my '71 a couple of years ago. I was filling up the reservoir every other day or sooner. I bought a bottle of 'NO LEAK' power steering treatment and it hasn't leaked a drop since. I also put it in my '82 Chevy p/u that had been leaking for years, plugged that up too. In fact Joel put it in the "APPLE" before Hot Springs and last I heard,  it wasn't leaking anymore either. It's worth a try. They even have a money back guarantee! I bought it at O'Reillys Auto Parts, $6.99 I think. Cheap enough fix.

Thanks for the info guy's, the rebuild kit is cheap...something like $20, but....for about $7.00 I may give the can of NO LEAK a try...today after driving the leak was small, so I assume it may have something to do with the position of the piston when parked.
