DW - thanks for the head's up. The reason I'm rebuilding is because one of the two shocks will not rebound all the way and is much softer than the other. It only rebounds out about 7" as opposed the to 10" it's capable of. So, I'm guessing it's leaked some oil out? Or could it be that it's leaked the nitrogen out? I've not done a whole lot of research on this yet, just getting started now.
Also, where do you go to get your shocks refilled w/ Nitrogen?
are the shocks on or off the truck?
Sounds like you might not have enough/any nitrogen in the one... you can replace with compressed air up to 180psi
You would know if it had leaked any of the oil.. it would be all over under the truck.
You don't want it to extension all the way out. You want to have the shocks limited (with limit straps) about an inch from full extension other wise in time you risk ripping the shock shaft out of the shock body.
We have a nitrogen tank at our race shop. I just scheme on nitrogen there. most off road shops will have nitrogen.
Where are you at ?
