Transfer Case Oil

Is there much difference between 75W-140 and 85W-140

I read that possibly only 400ml of the 600ml capacity may come out as the other 200ml is held in the sump

" If the transfer box is drained using the standard drain plug, there will be 250mls of oil left in the bottom of the box and even with tipping the car over, much of this remains. Unless you measure how much of that 250mls you get out, you're likely to overfill and the excess will blow out of the vent in the top of the box, giving the impression of a blown shaft seal on the righthand side. "

so would pumping it out be a good idea?

Somewhere on this site there's an article about drilling and tapping the bottom of the casing to put a drain plug in. I'll see if I can find it.Needs to be EP oil NOT Hypoid.

I used 75-140 Castrol differential oil, same stuff is used in the Nissan gtr and BMW diffs, so must be good stuff. Comes in 500ml bottles. I just kept flushing and running it till it started coming out a golden colour, took 4 flushes.

Thanks for the link Lost it

I was hoping to use the jack one side to drain, then jack the other side to fill while making sure all the existing oil is drained, hence the pump thought.

That's how I did it, no pump though as a pipe doesn't fit inside it, there's a bearing in the way.

You sure do as it just comes back out fast, found that out the first time I did it! Don't forget to completely wash the plug as mine had real thick black gunk stuck to it.

I rang tech helpline for a well known brand and they said to use CRX 75w140 NT so I bought some, then I found their which oils for your car guide and it says CRX LS 75w140 NT. I assume it is just best to get the one their site says

Just seen this

" The all-wheel-drive system is simple and full-time, operating through a viscous-coupled center differential. The front-to-rear torque split is fixed at 40-60, and the differentials are open at both ends -- no limited slip. "
