I need to install new front disc pads and have the rotors turned. The hub assembly seems to be a unit. Do I need any specialized tools to remove it? Are there any tricks or traps I need to be aware of?
Once you take the caliper bracket off, the rotor should just fall off. If the Jeep stops without any vibrations I would leave the rotors alone., unless they are scored badly from brake pads worn out and metal to metal.
Testimonial: "Thanks, that almost seems too easy. There is some pulsating but didn't seem to be any deformation when I checked it with a run-out gauge."

To install:
Assemble the disc to the hub unit and tighten the bolts to 40 ft. lbs. (55 Nm).
When installing the hub to the knuckle, use new self-locking bolts and tighten them to 33 ft. lbs. (45 Nm).
Install the steering knuckle.
Lower the vehicle and check for proper brake operation.
If equipped, enable the SRS system and connect the negative battery cable.
Before servicing the vehicle, refer to the precautions in the beginning of this section.
Remove or disconnect the following:
Front wheel
Clip, 2 caliper pins, the anti-rattle spring then remove the 2 brake pads and the 4 anti-squeal shims
To Install:
CAUTION Only replace brake pads on 1 side of the vehicle at a time. Failure to use this procedure could cause the caliper pistons on the opposite side of the vehicle to pop out requiring the reconditioning or replacement of the brake caliper.
Remove a small amount of brake fluid from the master cylinder.
Install a used brake pad into the caliper and compress the caliper pistons.
Apply disc brake grease to both sides of the inner anti-squeal shims.
Install or connect the following:
Anti-squeal shims to the new brake pads NOTE: When replacing worn pads, the anti-squeal shims must be replaced together with the pads.
2 brake pads
Anti-rattle spring and the 2 caliper pins
Clip
Front wheel
Depress the brake pedal several times to seat the brake pads.
Check the brake fluid level and top off as needed.
Warped disc, or loose brake caliper bolts, or brake pads without retaining springs or simply the pads have worn right down and you are receiving the bump warning on the disc. Remove the front wheel(s) and inspect pads and then check brake caliper retaining bolts. Turn the wheel so that you have an unhindered view of the rear of the brake caliper assembly. Rotate the hub and as you do so watch what happens to the disc rotor between the pads. If the disc rotor is seen to deviate from what should be a straight spin then it is warped and will need to be changed. Check the other wheel to be sure and to act as a reference to normal function...it is rare for both disc rotors to warp at the same time. If one disc rotor is at fault the general rule is to replace the other at the same time.
You got shutter ......do you mean shudder when braking and if so the problem with your brakes are that the pads dont work well with the rotors (dont care what the makers say) just see if you can get your self a set of PRIME disc pads and fit them to the front and make sure that the whole unit are bolted on tight and no movement in wheel bearings....

with caliper bleeder screw fitting and front disc brake rotor shield (2K004).
CAUTION: Handle
front disc brake rotor (1125) and disc brake caliper (2B120) assembly in such a
way as to prevent deformation of front disc brake rotor , and nicking,
scratching or contamination of brake linings/rotor surfaces. NOTE: To prevent damage, do not allow disc brake caliper to hang by the
front brake hose (2078) .
Remove caliper anchor plate bolts and discard. Position disc brake caliper
out of the way. Prevent separation of caliper housing from anchor bracket
because contamination of guide pin journals can occur.
NOTE: If excessive force must be used during front disc brake rotor
removal, the front disc brake rotor should be checked for runout prior to
installation.
If additional force is required to remove front disc brake rotor , apply Rust
Penetrant and Inhibitor F2AZ-19A501-A or equivalent meeting Ford specification
ESR-M99C56-A on front and rear rotor/hub mating surfaces. First, strike front
disc brake rotor between lug bolts (1107) with a plastic hammer. If this does
