Ok i know this might be the easiest thing to do but i never used them in all my years of towing ,i was a rollback guy..now having a wrecker i got a set of dollies...how the hell do they work??
Any pics or step by steps...All i know is they weigh a ton!!!lol
Oh man nobody posted ,someone has to be able to hekp me out????? 
Do you have popup dollies or the old style simple dollies? Errr in other words do the tires pivot and have a ratcheting mechanism? Do you have a big big long round steel bar with them?
I never used em till I worked for myself. They are a lifesaver when you need them! First time I used em was on a 1964 Jaguar junker that had been sitting for 30 years.
I would say there the newer style...been i never pulled them of the shelf yet..lolNot that i will need them often but i tow alot of jeeps and if i have a problem i would lke to be ablr to use them.
OK, first make sure you have all the parts. You have 2 dolly sides, 2 cross bars, and 1 jack bar (long piece of 1" or so steel).
Next you need to see if the dolly wheels still pivot. Mine were so tight it took hours and a torch to get them to turn. If things turn OK, make sure everything gets a good greasing to keep them that way.
Also make sure the bearings are properly adjusted and greased. Dolly bearings are highly stressed, so they don't last long. If you plan on actually using yours, install new bearings. And make sure you watch your tire pressures. Dolly tires are good for leaking down. Mine are especially good at it.
Now how to actually use the dollies. The cross bars lay on the ground, with the flat steel pads facing the tires. Then make sure your dolly wheels are pivoted UP, and lay the dolly sides down, then you drop the cross bar ends into the dolly sides. There are multiple slots, you get the crossbars in whatever slots make then the closest to each other.
Then you put the jack bar into the jacking slot, and pivot each dolly wheel down to raise the dollies. You are supposed to pivot the front wheels first, then the rears. Make sure you engage your pivot locks after each wheel is pivoted down.
You should also have a set of straps to loop around the tires and strap to the dollies. This keeps the dollies from coming loose on bumps.
Once you get the dollies on the ground they aren't that hard to figure out.
BTW, you really only need to use dollies on AWD's or vehicles that the wheels won't turn. Most 4wd's can be towed fine with a wrecker, they just need to be in 2wd. All I use mine on is junkers and wrecks where the wheels won't turn, or to get FWD cars out of parking spots when I don't have the keys.
he about covered it, just make sure you keep your body clear of the arc/path of the bar as you do the lift, I almost clocked myself good in the head once on a rainsoaked night when one hand slipped of the end of the bar. thats what I get for having my mind on a nice warm/dry cab instead of my worki.
i work on hampton beach in nh and in summer time we do a lot of dolly tows.some of these cars are up against a guard rails and a long bar will not work,so we have the bar like the one listed below in addition to the long bar

For those cars up against the walls try using a set of gojacks. I use then from time to time. They are very helpful.
i dont have the room on my truck to carry the go jacks,thats why i have the short bar
I once had to pull a FWD out of a garage and did not have room for the bar. We don't carry gojacks on the wrecker. So a little scratch on the noggin and hey! I often will use the wheel lift or boom to pick up the end of scrap with no wheels sit up the dollies under already locked. So when you can't do that grab your service jack and raise that corner high enough to lock the dollies by hand. Remember some people see towers as the Boy scouts of the road. And No Tow No Pay.
