Front diff output shaft rubbers?

[motopreserve]

Hey folks. I am in the process of installing the axial AX31182 front diff locker. It came with its own output shafts, which I am using. I realized when I took the old parts off that there were 2 small rubber "stops" inside the stock output shaft cups (inside end of dogbone would hit against them).

These rubber pieces are not in the diff locker package, nor do they appear to be listed on the parts list in the manual. They also are not in the axles/cups at the wheel end.Should I be reusing the ones from the stock outputs? Just thought it strange that they wouldn't show up in the manual if they were needed/preferred, and I have not been able to find any info in my searches.

Thanks in advance.

they are to keep the dog bones tight and not sloppy sliding left to right.
if you have not switched to the longer 94mm universals i believe you should reuse them.

Wow that avatar is distracting....were you saying something? Oh yeah, less slop

I do have the exo universals (not newer yeti specific) to install. So I'll check it with those and see how she goes back together.

Thanks!
