GQ Transfer Case Oil Change

[SiNH]

I understand there are filler and drain holes in the front, rear and gearbox sumps. I was wondering how you go about changing the oil in the transfer case?

As far as I can see and indicated in the Gregory's workshop manual there is only one sump plug in the transfer case.

How do I drain and refill the transfer case?

Your help would be extremely appreciated.

on the rear of the transfer case you will see a 1/2 inch drive or square socket drive and also above this 1/2 way up the transfer case you will see the same thing . fill on level ground till the oil just runs out

but remember to use the correct oil

Remember, ALWAYS remove filler plug 1st...
In case you drain and then cant get it out!! to refill.

Im using all the Penrite recommended oils specified on their website.

The only thing different is instead of Limslip 140 I am using Penrite LIMSLIP 85/140 instead. Is this OK? or should I harder to hunt down the LIMSLIP 140?

It wont cause any damage will it?

Be careful, some of them take auto trans fluid in the form of Dextron II & you will have problems if you dont use this ir an equivalent. As mentioned the synthetic is excellent. If I am not mistaken Limslip will be a heavy gear oil which wont be suitable.

Transfer case???

Use that in the 2 diffs. I prefer the multigrade. 85/140

Nah not the transfer case, I was refering to the rear diff.

You are dead right on one thing though, always undo the filler plug first incase you dump the oil and no way of refilling it up again.

Needless to say I only managed to change the manual box oil. The filler plugs on the 2 diffs and transfer case wouldnt budge. I might have to bite the bullet and get the mechanic to do my fluid change.

Thanks for the headsup.
