No air tools. Except to try and remove the lug nuts. Installed using torque wrench and manual 1/2" sockets and I did one side a day, because of what I found. You won't have the problem I had with over torqued lug nuts. Had my dealer replace the motor and gear box for the bedroom slide so I had them grease the bearings at the same time. I had to use a three foot pipe with a breaker bar to get the lugs loose. The air tool could not budge them. With two of them I was lucky to get them off having to use the breaker bar to turn them all the way off. The threads in the lug nuts and lugs pealed off. I had to replace all the lugs and order new lug nuts. My dealer has not seen me since. Do properly torque the hardware and remember to keep the wet bolt grease holes pointed to the front or rear, Otherwise all the pressure from the weight of the fifth wheel will keep you from getting grease pumped in. Do put a light coating of grease on the wet bolts prior to inserting them in durning assembly.
So take your time and be safe. This is heavy work and if rushed, you can get hurt. Done in a careful way it it is not a problem.
