New Eaton Front Locker

[RuggedH2]

OK, so I just ordered my new Eaton front locker. I'm having it installed at 4 Wheel Parts in SLC. In case anyone is confused by my username, the locker is for the 06 H2 I bought from Timgco.

I was planning on running the Royal Purple gear oil in the front diff, but the techs there told me that due to the Rancho lift and the angle of the CV shafts, it could run dry with the heavier weight synthetic.

Anyone out there with a FabTech or Rancho lift - running synthetic in their front diff? Any problems?

I'm just gonna run the switch where the air ride button was located, because mine isn't equipped with that, and I saw that was where PhilD put his.

Anything else I should be aware of with this mod? Thanks.
