I found a steering valve seal rebuild kit through Ecklers. I want to get rid of the slop in my steering which Iv'e pinpointed to the valve, but I'd rather spend $20 than $190 for a rebuilt one. I veiwed the instruction sheet in the item description and it sure seems fairly straightforward. Has anyone successfully attempted this rebuild and if so would you recommend doing so? Also, is it likely to alleviate the slop like purchasing a rebuilt unit certainly would. Any advice on this subject would be greatly appreciated!

I tried the seal rebuild kit.  It did not improve the steering situation.  I ended up putting on a rebuilt unit.

Thanks for that nasty little warning! I'm glad it didn't turn out worse for you than it did! I don't think that I will think again about attempting the rebuild. If your experience netted no improvement, I doubt it would be any different for me. I'll just buy a new valve. I guess it would be wise to replace the cylinder and hoses at the same time as well. Thanks for sharing your experience with me.

The reseal/rebuild kits will not remove/repair any "slop" in the steering...just stop the leaks. If your ball/socket is worn, it will need to be replaced, and these do not normally come in the O/H kit...just the seals. The ball/socket parts are available, tho, thru some of the Corvette vendors.
The basic reseal is not that complicated, and can be done in a couple of hours. Replacing the ball stud will take a little longer, tho.

The best way to not get your wrist broken after doing a steering valve repair is to leave the end of the cylinder loose from the frame of the car, until it has been adjusted properly.
Don't feel bad, Tom, you're not the first one to learn that the hard way.
