I'd like to encourage you to do this yourself. It's not that tough, but it may require some specialty tools (or at least some improvisation).
I am not sure which "6 bolts" you are refering to, the ones holding the rotor to the hub assembly, or the 6 allan head bolts on the cap of the auto-locking 4wd hubs. But, to get the rotor and hub assembly off, you have to remove the auto-locking hub assembly - - that means the allan screws.
Here's what you do...
- Remove the 6 allan screws and remove the cap.
- Remove the spring and flat washers inside that slide off of the spindle (take note of the order and position/orientation of these to put them back in the same order.
- Now remove the lock washer holding the wheel bearing and hub in place. This is similar to the large lock "nut" that you may have seen on other vehicles. The lock washer is threaded onto the spindle. Before removing this washer, you must locate and remove the small screw(s) that keep the washer from spinning.
- Once the lock washer is removed, the hub and rotor assembly will slide off the spindle - bringing the outer wheel bearing with it.
- Once this is off, you can now unbolt the rotor from the hub.
Reinstallation of the hub assembly is the reverse of the above. Just make sure that you fully grease (re-pack) the bearings before reassembly. You also want to make sure you seat and pre-load the outer bearing properly with the lock washer, before replacing the screws in the lock washer.
Now, depending on your comfort level with mechanical things (I don't know you, so forgive me - I don't intend to offend) this may seems a little overwhelming at first, but with the right tools and a little time, it's totally do-able. The only "specialty" tools required would be for torquing (pre-loading)the lock washer, but these can often be borrowed, free-of-charge, from a parts store.
Might I also suggest you pick up a Haynes repair manual (I actually have a Chilton, but I understand it is not as good as Haynes), which should describe the above process pretty well.
Anyway, if you decide to do this yourself, have fun with it. And let us know how it turned out...
