On the DT-generation Ram 1500 the front bearing is a sealed bolt-on hub unit with the ABS speed sensor built into it, so there is no pressing, no shims and no bearing preload to set. The real work is breaking the 36 mm axle nut loose on a 4x4 and then getting a hub that has rust-welded itself into the aluminum-and-steel knuckle bore to come out in one piece. Budget for a slide hammer with a bolt-on hub puller — that one tool is the difference between a two-hour job and a ruined afternoon.
Engine choice makes no difference here; 2WD versus 4x4 does. A 2WD DT has no axle shaft or axle nut, so it is essentially caliper off, rotor off, four bolts and out. The mistake people make most often is not cleaning the rust scale out of the knuckle bore before fitting the new hub: the unit sits slightly cocked, you get runout, a vibration and a bearing that howls again in a year.

Tool sizes are identical across the 3.6 Pentastar eTorque, 5.7 Hemi eTorque and 3.0 EcoDiesel — the hub, knuckle and 22 mm lug nuts are shared. The only real split is drivetrain: 4x4 trucks need the 36 mm axle nut socket and heavy breaker bar, 2WD trucks do not. Trucks with the larger/HD brake package may use a different caliper bracket bolt head, so check 18 mm and 21 mm before ordering tools.

No. The DT uses a sealed hub/bearing assembly that bolts to the steering knuckle, so it is a bolt-off, bolt-on part. You only need pulling tools if the old hub is corroded into the knuckle bore.
36 mm, 1/2 inch drive. Use a 6-point impact socket and a long breaker bar or impact wrench, and hold the brake or lock the hub with a pry bar through two lug studs while you break it loose.
Yes, the wheel speed sensor is integrated into the hub assembly on the DT and comes with the new unit. That also means a failed speed sensor usually means replacing the whole hub.
No. Nothing that sets camber, caster or toe is disturbed, so the alignment is unchanged. If the truck pulls or the steering wheel is off-center afterward, something else was loosened.
