Use a thin flat blade screw driver and pry the plastic chrome piece off the bottom, and the plastic chrome trim on the top, get a large pair of pliers and give the knob a couple 1/4 turns each way then just pull off. They are not threaded and as long as you are careful it will all come off with no damage. I swapped mine out about a month ago, but I didn't take any pics of the process, sorry.
Plastic Shifter Bezel Broken? No Need to Remove Knob!
The plastic bezel separated from the shifter boot on my 2008 Wrangler 'X', 6 speed manual trans.
The factory plastic bezel is held on by plastic nubbies that, when broken, offer little option but replacing the bezel.
I suppose that one could drill holes in this bezel and buy some small hex bolts and nuts and reinstall the old bezel easily enough, but I found a nice billet aluminum bezel in my Quadratec catalog.
I installed the Rugged Ridge (black anodized) bezel easily, WITHOUT REMOVING THE SHIFTER KNOB!
I read all the posts about removing the shifter knob, gave mine a few pretty hard tugs, and then realized that even thought the directions specify removing the knob, I wouldn't really have to.
I would recommend laying down a sheet under your work area, though, because the screws, nuts, and washers are pretty small and your fingers are not--reminds me of a joke;
Q: Why do Gorillas have such large nostrils?
A: Have you ever seen their fingers?
Anyway, guaranteed you will drop one and it'll go directly under the seat and find it's way under the carpet pan never to be found by you. (Or me, in this particular instance).
That is all.
...my other ride also gets crappy mileage.
