Removed the steer tires tonight, everything went well for once on a 30 year old coach. 40 minutes to break 20 lugs loose with a 6 foot cheater bar with normal effort. None of the studs appear overstretched. Once loose I was able to chase the treads with just a gloved hand on the socket. Hit them with PB Blaster lubricant last night and a wire brush. About 5 looked severely randomly corrrored for some reason. Will have to have proper double ended tool for the rears. Bubba's impact wrench must have been getting weak, or the shop air pressure had dropped really low.
Let me know if you ever need a hand. I'm not far away and have a shop full of tools.
Thanks Jacob, was just in your fine city last Friday to look at a project at GKN Aerospace.
I work just south of there at Triumph Accessory Services. I do have a 600 ft/lb torque wrench if you need one.
Drove 20 miles to The Big Tool Store today and got the special socket for the duals. That place has every tool you could imagine and is quite large, with plenty of knowledgeable staff who found what I needed in minutes. Yes they had a 1000 ft/lb torque wrench and even a 4:1 torque multiplier for those 4000 ft/lb bolts , both expensive. Lot's to look at a drool over, spent 90 minutes looking at different stuff. Will attack the duals tomorrow.
With the special socket and HFs cordless impact wrench, removing any wheel on a Foretravel should be easy. $270 with 20 percent off this weekend. 1200 ft-lb of torque. A tow truck driver used one of these on our U300 while I was at a funeral. Easy off and put the spare on too. No need for an air impact and hoses.

There's another socket you should look at we call it a sheep's foot. Sometimes the outer nut unscrews the inner nut(or outer stud) and this holds the outer nut while you spin the inner nut out of it.
Ok, slightly confused now, Oshkosh manual tells you to only snug the inner nuts? Lower to ground and torque. So do you repeat this for the outer nuts.
Is removal reverse of this or can you get by busting loose the outers first on the ground running the nuts a few turns out, and then bust the inners loose.
I'm a newbie to duals
Crack the outers, jack and remove the outer wheel. Let back down, loosen the inner nuts, etc.
Try to get the nuts snug enough to center the rim to the studs. let down, torque. Repeat for outers.
I would not loosen both the nuts and studs with the rims still on. If you get a thread glitch, you have a heavy hassle .
