Brian, do you have any battery tools? Get a grease gun that uses the same batteries. That way it won't poop out halfway through the job and need to wait to recharge.Jess sells 22 ton pin type jackstands and aren't anywhere close to $600. Should be available at Napa or other places.
Even with the axle raised with a HF air operated bottle jack, is there enough room to slide under and do steering, Pittman arm, etc? Guess he doesn't have ramps.
Yes, there are cheaper jack stands, but I buy made in the USA when possible. I found some open box 25 ton Hein-Werner stands on Ebay for under $350. I had the same thought as another poster of just using wood instead of jack stands although I might very well need the jack stands again. I already have an air operated jack that will lift the bus.I have lots of Makita cordless tools including ten batteries, but I would be willing to go with another brand if their grease gun is significantly better. I also have some Dewalt 60 volt/20 volt batteries and some Ryobi batteries. Dewalts makes a cordless air compressor that Makita doesn't make and Ryobi sold a cordless miter saw long before Makita ever did.
If you only grease the bus once a year, wouldn't a $30 hand grease gun be enough?
