Differential grease renewal

[Hunter90 HD]

Hi All,

I am wondering how often do you replace the grease in your diffs and how do you tell when they need to be regreased?

Cheers!

The savage uses a relatively weak bearing on the cup side of the diff, it doesn't typically last all that long, so whenever I change that, I clean off/regrease the ring/pinion since you have to completely disassemble the diff to replace the bearing. I clean the entire diff with soap/water before taking it apart to avoid a mess.

I don't run my nitro savage nearly as frequently as I used to, but when I ran it frequently, I'd change that bearing a couple times a year.
