How To: Changing Differential Oil (VZ)

[sixes]

Mineral oil is perfectly fine.

Just did my diff oil because I was not sure if my mechanic added oil to top up or drained in the past. 120,000 ks on clock my diff is an LSD
My oil was pretty decent, certainly nowhere near as black as the pictures on previous pages.
Anyhow, my expenses were getting a 30 mm socket ( $18.50 from Bunnings for Sydchrome) and a $30 oil pump from Supercrap, plus 2.5 ltrs Penrite PRO GEAR 80W-140 (Full Syn.) ( with 25% off Repco voucher $41)
All up around $90 and I know my axle is in good shape. So I am quite happy

If I don't have a level surface is it ok to drain with the rear lower than the front?

Fine to drain

To fill, how about jacking the vehicle up from the rear? Will make the vehicle level to fill it up. Give that a go.

So I am going to do this soon as I can’t see anything in the service records that indicate it’s been done before but does a 2006 VZ Calais have an LSD I would assume it does but can anyone confirm or how would I check that.

Btw fantastic write up

Hop under the car and look at the tag that should be hanging off the fill plug. It will have LSD stamped into it if it is LSD or check the sticker on the side (if not worn) as per IPCOlsenVZ's post.

What a great thread! I tackled this job yesterday, bit of a squeeze getting under there with FE2. The old oil was seriously degraded, who knows when or if it had ever been done before? The Nulon Ezy squeeze bags worked well ($20 each Supercheap) and can feel a significant drive line improvement.
