Replaced my ignition cylinder with a new dorman cylinder kit. new kit came with new tumblers (which I used) and keys (which I tossed). all in all, about 15 minutes of work.
occasionally ill need a coworker to move the jeep at work and sometimes ill find the radio is on and the key is out of the cylinder. I know my key is good, dealer cut a replacement off the vin last summer. low and behold I realized if I improperly removed the key before pushing the plunger I could pull it out too. so I figured it was time to do the tumblers.
its a easy job. luckily my model year had a hole in the plastic cover under the column you could push the release button on for the ignition cylinder and simply just pull it out with the key in the on position.
after its pulled from the column theres a bit of a trick to get the inner cylinder with the tumblers out of the outer cylinder but its as simple as pushing a pin in with a knife and viola the inner pulls right out. (inner left, outer right, center bottom are the tumblers and springs) this is the original cylinder shown here after soapy water, it was full of black tar like gunk and grit.

And when comparing old tumblers (top) to new tumbler (bottom) you can make out the wear. they were ground away over the near 200k miles of use. I circled the common wear spot on one of the old ones but all three of the originals show wear. out of the 8 tumblers, 6 were worn with a grove.

This kit did not provide any lubricants of any sort unlike a ford dorman kit I did earlier this year where it was supplied.
from what Im assuming, the ford kit had steel tumblers which required grease but it is also in a enclosed cab. whereas brass in this jeep kit is a softer metal "self lubricating" and is in a open to the elements environment with more dirt and dust therefore you wouldn't want grease packed inside collecting dirt. maybe.
