It is possible! I was able to complete this without removing the rack from the truck.
Since I was unable to find any information on the replacement for the newer rack design, I figured I'd share my experiences here.
I decided to replace my rack bushings because I was starting to get some scary handling characteristics in the rutted lanes on I70.
Remove the skid plates and the two bolts holding the rack in place. There is enough clearance to get a wrench on the nut on the top of the rack. Be sure not to loose the washer from the top of the rack.
To boil it down, the bushings rubber with metal sleeves and are pressed into the rack itself. Each side has a top and bottom bushing. Much like you'll see with the Whiteline replacements. What you'll have to do is pry out the rubber center of the bottom bushing, and then using an air hammer, you can drive the top half out as a complete piece.
You'll find on the passenger side that you also have enough room and play in the rack to use the air hammer to drive the shell of the bottom bushing out.
On the driver side we're not so lucky. After driving out the top piece, I then used a dremel to carefully notch the lower shell and used a screw driver to start driving the shell inward. I found that once you have driven the shell, using the hammer and screwdriver (or drift) you can spin the lower shell out of the rack.
Putting the new passenger bushing is very straight forward. For the driverside, I recommend you place the metal core of the new bushing in the rack first, and then place the top bushing half on and work it down into the rack and onto the metal core as far are you can. Then insert the lower half of the bushing. Make sure you get it as far into the rack and onto the metal core as possible. Then use the original bolt and nut to pull it together and into place.
Torque to 90ftlbs, or as indicated in the factory service manual.
EDIT (01/28/2020): At the request of others I used the Whiteline W13208 bushings.
DO NOT FORGET TO USE THE SUPPLIED WASHERS WITH THE NEW WHITELINES
Here's the timelapse with basically zero editting:

W13208 - Steering - rack and pinion mount bushing
Power steering, aggressive wheel alignment geometry, wider wheels and lower profile tyres have all put radically increased loadings on the steering systems of modern cars. Add to that engine bat contaminants such as oil leaks that also help to degrade the performance of steering rack mount...
