The GMC Jimmy is rear wheel drive. The only time the front wheels pulled is if it was a 4x4.
The complete hub and rotor assembly have to be removed in order to drive out wheel studs to separate the rotor from the hub. So, remove wheel, remove caliper, remove caliper bracket, remove axle retaining nut, remove 4 bolts holding hub assembly to spindle, dissconnect ABS sensor harness, remove hub assembly, remove all wheel studs then separate rotor from hub.
On a 4-wheel drive it is free floating and on a 2-wheel drive you have to remove the axle nut and bearings. From what I have heard in the ford forums is the 4-wheel drive free floating can be hard to remove if they get rusted in place so be sure to have a rubber mallot on hand. I just replaced my front rotors on my 2-wheel drive and it was real easy to get off.
You will have to remove the front axle assembly to have enough clearance to remove the oil pan in vehicle.You will have to remove the front axle assembly to have enough clearance to remove the oil pan in vehicle.
They didn't make this one very easy to replace. Start with jacking up the front end and let it down on jack stands under the lower control arms, then remove the wheel, brake caliper, axle nut, disconnect abs speed sensor harness, remove the bolts holding the hub assembly to the knuckle and remove the hub assembly with rotor attached. Once you have the hub assembly off you can drive out the wheel studs and remove the rotor.

You have to remove the wheel hub assembly, drive the wheel studs out with a hammer, and flip the assembly over to remove the rotor from the back side.The wheel hub assembly removal requires removing the caliper, 1 11/16 inch nut on the axle shaft, loosening the 4 bolts (14mm 12 point socket) that hold the hub to the knuckle, and hammering on the bolts to loosen the hub. ( use a sacrificial socket to save the bolt heads).You have to remove the wheel hub assembly, drive the wheel studs out with a hammer, and flip the assembly over to remove the rotor from the back side.The wheel hub assembly removal requires removing the caliper, 1 11/16 inch nut on the axle shaft, loosening the 4 bolts (14mm 12 point socket) that hold the hub to the knuckle, and hammering on the bolts to loosen the hub.

If it is four wheel drive, the front axle assembly will need removed to access the oil pan.
Remove the tire and wheel. Remove the brake assembly and rotor. Remove the axle end cap. The rear hub assembly will come off.
The rotor and hub is an assembly, you need to take the wheel off, remove the brake caliper, use a hex drive to remove the lockout assembly, then there is a special socket you need to use to remove the bolt holding the hub in place.
to remove the spindle and four bolts hold the bearing assembly to the "A" frame. remove the wheel, remove the control arm, remove the lower "A" frame , and remove the CV axle. then you will have acess to the 4 bolts that hold the bearing assembly. you will have to buy the whole assembly.
1)raise the car and remove the tire.2)remove the brake caliper.3)use a screwdriver to remove the hub dust cover.4)remove the cotter pin,adjusting cap,wheel bearing nut and washer.remove the outer wheel bearing.5)remove the hub and rotor assembly.
