DLR item only?
Inside the housing. It seals the shaft. BTW, the gear is nylon or delrin, not vinyl.
x2 It's a bitch to get the old one out if you don't have the right tool. You can hardly see it. I used a set of dental picks and it came out pretty easily.
should probably do the orings...they're probably due for new ones anyways

This is the gear on the back of the transfer case, correct? Not any gears in the dash end?

Appreciate the clarification. I know that there are non-metal gears inside the speedo itself, so thought possibly that was the focus.

Be certain you get the correct one: there are several versions for various size tires/gear ratios.
I bought mine from SOR. You have to know how many teeth are on the plastic gear so it would be best to remove it first. That is what I did and it has been working fine for about a year now.

there should only be one for a 78' fj40, they only came with 4:10's and 235's right?
SOR lists 16, 17, 18, 19 teeth S/D gears for 1965-1980

only 18 teeth for the 78'
You can change teeth if you have other than stock size tires and your speedometer will be more accurate. Hint Hint.
