Is grease/lubrication a DIY on your rig?

If you're looking for a grease gun, get one that takes cartridges, has a short 8-10" hose on it and uses a pistol grip. That way you can hold the gun with one hand and hold the head on the fitting with the other. It's an easy job, whatever size rig you have and will let you get under there and see all the other things that should be checked, and aren't when you pay some grease monkey to do the job. Things like leaks and seeps, loose wires and lines and loose bolts or other things that need attention but are usually missed. Time VERY well spent.
