Bump, has anyone done this yet?
yes- sort of, I guess.
The differential is installed, I just haven't had time to wire it.
There is a bit of an issue that could better be overcome, with enough time and research. That is, getting the wires out of the differential. The factory axle this comes in, is entirely different than the one on these non-PW, newer trucks (Even to the point that a ring adaptor/spacer plate and longer bolts are required for the install - available from notjustdifferentials.com). There is a hole in the differential housing for the wires to pass through, and a sort of hold down clip & seal which matches that hole. This is simply unusable on the axles for which the differential did not come standard. Not only that, from what DTS found while researching this for my install, the parts can't even be ordered.
So, the solution we came up with was to cut the plug off, drill as small of a hole as possible, to feed the wires through, then fill the hole with RTV. Not what I'd call ideal.
I believe with enough time to find the right set-up, a hermetically sealed pass-through would be the RIGHT way to do it. But it would take some work finding one, then figuring out how to get a good seal against a curved surface.
I will get it wires up to the factory aux switches, and run it as is for now. I'm going to try to find a pass-through solution in the next 30k mi, and hopefully I'll be able to improve the situation on the next fluid change.
I don't know if the factory PW axle would be a drop-in proposition, but if so, it might actually be a better option to try sourcing a used front axle. Well, maybe not- it's going to be geared more in-line with the gasser, so gearing would have to be changed.
If I find a good pass-through option to give a more reliable seal, I'll be sure to post back to here.
