First thing I would do is power wash it and try to get some of the crap out of it. Then I would spray it with some LPS or WD40 to get the water back out and then try to lube it up some.

 

Is there a cap/plug on the cylinder (in front of the handle)?

 

nothing on the cylinder, just a flat head and an allen head that you can see from the pic, i dont want to unscrew any thing because it might be under pressure

 

If the jack handle is twisted all the way to release, nothing should be under pressure. One cap will probably have a spring and check ball under it, the other should be the fill port.

 

i'm going to look at the front of the handle again i was on this site and saw this http://www.hyjacks.com/H7.HTM thanks for you help.... glen

 

after looking at the jack again i lowered the handle all the way down and low and behold there was a rubber stopper,just like the one in the link i posted, pulled it off and saw some oil down there, so thats it! thanks for helpping out, now i can rotate my tires on my 98 blazer 4.3l 213,000 miles and counting

 

I could have sworn that most all jacks have a fill hole in the main body of the cylinder.

 

jack works great now, thanks for you help
