I'm trying to determine if I should replace the Power Steering Cylinder in '74. I know these are welded/sealed units and the internal piston is not serviceable, but how do I know if the internals are good or not? Is there a way to test these units to determine their condition?
Any help you guys can provide is greatly appreciated!
If it works presently and appears to do so 'normally', you don't need a new cylinder. The only things to wear on that components are the piston rod seal [at the end of the cylinder], the ballstud joint, and the piston seal inside. You can easily rebuild that cylinder by changing out the first two items; and if it works, you don't need to change the third one.
Thanks 7T1vette but the problem is that I have the car disassembled doing a full restoration, so I an't check the cylinder right now. I know that the power steering system leaked some before I took things apart but was never sure if it ws the PS control valve or the PS cylinder that was the source of the leak. As everything going back on the the car is dissassembled, cleaned, painted and reassembled beforehand, I pretty well know that all is "like new"..... except for this cylinder which I cannot take apart fully.
I would prefer not to reinstall this part only to find out in a years time that its junk and I've wasted time and $$ installing new outer seals, cleaning and painting it. Surely there must be some way to ensure it internals are up to snuff???
You can take your chances with a "new" aftermarket part...or keep the one you have and rebuild the seal and ball stud. It's your choice. Just tryin' to help....
