Hydraulic Jack Rebuild

While rotating tires on my car, the bottle jack starting acting very strange. I had rebuilt it several years ago, so I figured the O-rings had gone bad again. Follow along as I replace them again. This is a good way to kill about half an hour and in the process, save about $30. O-rings can be had in packs of 10 for $1-$2 per pack. This will allow a jack to be rebuilt 10 times for less than $5.
