Thread: What happened to your D3/D4 today?

There is like a coke bottle in the front hey, 0.6 l I remember the first time I did it. I didn't look it up and had like 4L to get through

So Shane, how often to change front diff oil - annually/20K not overkill?

Yeah good question, I reckon 20k is a little soon. I'd target 30-50000km between changes, depending on usage. If your running a fair bit of extra load then 30k would be fine. The rear can go about double the front diff, but if your doing one might as well do both

Today I’ve been pulling cable and refining the upgrades.


Fitted USB ports to upper glovebox


Same for the console


Terralume upgrade in the rear whilst I’m in there running camera cable.


New rear door cover (still waiting on the black/silver badge)


When that’s all done - need to open this box…
(It’s the replacement high stop lamp)


Prusa is currently busy printing me a new case for my Xlifter - it’s going into the spot beside the terrain response this time.

Fitted the bar for some extra lighting up front.
Watched this during some downtime. D4 recovery.

Well. It’s alive.

Waiting on parts/cable to patch in the factory microphone rather than adding another.

Won’t be too much longer and I can refit the dash panels.

Deserves its own thread I think Tombie…
