what ever ur manual says or the bible should have it, tc is around the 80w mark and the diffs i use 80 to 140? grade.

[sanger]

thanks bazooked.

yeah i use 80w140 its great except its a bugger to pump it in
cuts abit of the niose out too

[Nev]

ive always used 80w90 penrite gear oil in both diffs and transfer as per penrite catalogue and mechanics advice and no probs at all

[zookjedi]

i use 85w 140 in diffs tranny and transfer case , it would be a real pain putting it in but i just use a 20lt drum pump as i get the oil in 20ltr drums

[sanger]

Thanks Nev and Zookjedi much appreciated.

No no noise problems. I have the tcase out getting reduction gears installed so was wondering what oil to put in when its all together.

As for the diff oil im welding up the front hemisphere so ill need to put oil in after its all together.

Cheers.

With all new parts and new beaqrings and seals, I'd recommend the recommended oil (from owners manual and/or gear makers info), which I think is 80/90 gear oil.
Thicker oils are just for cases already knackered. Oil too thjich often doesn't lubricate properly. Not sure if the additive in lsd oils is good for t-cases or not

I use LSD oil in front lockrite, straight 140 LSD in gear box, t-case and rear diff...but there ain't no expensive bits in mine.

I will be using gear and transaxle oil made by castrol think its 90w and for the diff ill use the diferential oil by castrol aswell but cant remember the thickness etc.

Have anyone with reduction gears used this oil if so feedback would be appreciated.

[sanger]

Also i need clarification on the oil capacity of both transfer case and diff in a 1.3l sierra. I think both are 1.3L but am not quite sure. Can anyone shed some light on the subject for me.

Cheers

On the diff's go til you fill it up... for clarity I mean park it on a flat surface and fill it til it reaches the bottom of the fill hole.... (make sure you have the drain plug back in)

Thanks for replying but i would like to know specifically so i know if i can get away with 1L bottle or whether i will have to buy 2 L.

[christover1]

I believe front diff is 1.5 litres, gearbox is 1.3L, t-case is .7-.8L(depending on which book you read) and rear diff is 1.0 or 1.2(seen both these figures)..
But this can change with lockers and diff welds taking up a bit more volume.
I have only got 1.0 litre info, so those figures aint hard facts.

8ooml in the transfer is correct . cheers ron

[sanger]

thanks for the reply christover1.

ronoor thank you for clarifying. Do you know the exact capacity of front diff?

Ended up using castrol VMX 80 and it works a treat. Reduction gears are so nice. Clutch is much more happy now

agree about new parts just use recommended oil etc but i think you are misguided saying thicker oils are for cases that are already knackered . my gears look as good as when i bought them 3yr ago (s1) and ive been running 85w 140 since i installed them , thicker oil is better for constant hard driving its better than the thinner oils under load , but not so good when car is still cold as it dosent run as freely( around bearings etc being so thick until it warms up .

yeah mine is a bit slow till it warms up.
Especially in Winter.
Gears are a bit hard to change until the first few k's.
Can't feel the difference now its summer, tho.
Sure a lot quieter than b4 and I agree about heavier use making heavier oil better, mine certainly gets worked hard.
But I don't like to recommend wrong oil, especially if warrantees are involved. I love it though.
