Changing Rear LSD Oil AND Front Diff Oil

[HantsHog]

Just read the sticky on "Spin Out LSD Issues" as my T2 scared the hell out of me and the kids when towing empty trailer on damp road existing roundabout at 25mph!

Anyhow, if I need to replace my rear LSD oil is it advisable to replace the front diff oil at the same time?

For the rear axle you must use LSD oil:thumbs it wouldn't hurt to change the oil in the front diff but it's a different oil which I can't remember off hand:doh Making sure the tyre pressures are set correctly helps a huge amount when it comes to road holding & wet road grip & for some reason a lot of people think there should be around 40psi in the tyres:doh:doh fronts are 26psi & rears are 26-29psi depending on what size rims are fitted but the info is on a sticker on the drivers door opening unless someone has pulled it off:doh & don't use 4WD on the road as these don't have a centre diff:augie

Front diff is API GL5 takes 1.3 litres.
I run 26 psi most of the time in my tyres.
Put the rears up to 28 psi if fully loaded or towing.

I've got 17's on mine which run at higher pressures 26F (I run fronts at 27psi as I get perfect even wear at that pressure) & 29R but loaded the rears need to be 32psi

Mine are 33"tyres so played around with different pressure until it looked and felt right. Any more than 26psi and I am running on the centre of the tyres and handling is crap.

Whoops... I'm on 33psi

They still look partially saggy at the bottom.

Having the correct (and regularly renewed) lsd oil made a massive difference in handling for mine. But, as said, make sure you use the correct oil. Check the labels on the bottles yourself, most shop owners (even garage owners) will sell you whatever brings in most money.
Oh, and don't undo the drain plug before you have checked the filler plug can be opened as well

I had a roundabout tail spin too, caught it before a complete 360% happened. I don't know if it was oil on the rd or the LSD.
I renewed the oil in the rear diff and also fitted matching rear tyres as that helps.

If rear sliding is caused by LSD oil being overdue for a change then I would recommend 2 oil changes carried out 50 to 100 miles apart. this will flush out any debris. the symptoms are likely to return fairly soon otherwise. In future don't leave it so long LOL.

I was under the impression that LSD oil could be used in the front axle also. It's certainly essential in the rear. I use a (very expensive but I got it freeeeeee) full synthetic 75-80 in my front axle, as I did in both F & R axles during 75K+ of Frontera ownership. This is thinner but more stable than std. grade oil, working on the assumtion that continuosly rotating 3L axle will then waste less fuel. If only.....
