Just serviced my R32 GTS-t gearbox and diff.

I used Redline shockproof gear oil, expensive but the best. Can't remember the weight, I think 40w.

On the R32 I needed 2 liters for the gearbox and 2.5 liters for the diff. This sucks as they sell the redline in 4 liter bottle. I topped up .5 ltr with motul gear oil from 1 ltr bottle.

Unless you have a hoist it is a bitch of a job!!

I took mine to a mech friend and they did both gearbox and diff for $35 as I supplied oil.

My diff was super noisy and is on the way out but much better now with new oil.

It's not worth the drama of lying on the floor with gear oil in your face for $40.

Fuel filter is a throw away item. I replace mine every 10000kms. No inspection or cleaning possible as sealed unit. I think you can leave them for 30000kms.

Hope this helps.

Just jap have them in stock. Use genuine only. I think the above price is about right.

Check to make sure they sell you the right one, some are a straight filter (no bends) and the other has a 90deg bend off the top of the filter. Check your current one.!!

They sell the wrong parts all the time.

Grippy.

I would think that the R33 box oil qty is similar to R32. Can't be sure though as I don't have a 33. Maybe slightly more but 5ltrs should do it.

did it get rid of the whine? how easy was it too change?

[DjeMz]

Still cant find a step by step guide

Anyone?

[Kinks]

there is definitely a thread about it in general maintenance. search function sucks but this has been covered many times before.

1) remove old oil

2) fill with new oil

3) ???

4) profit

there you go

I would avoid using a redline gear oil in the GB. I know many people here do but I would recommend the MT90 (75W90) over shockproof. Shockproof is a 75W140 and has more friction modifers for LSDs as its a gear oil and from my experience MT90 shifts better. However I know many ppl here have used it and I would rather have it than mnay otehr oills on the market.

If in doubt use Motul 300 gear, top stuff also.

THe GB takes about 4lts when u refill, the diff takes 1.2 ltres. I did both today as it happens. Both require a 1/2" drive wrench to get out the plugs...easy if u have a pit like me.

2.5 litres for the diff???????? damn. is it the truck version lol. should be 1.4 litres. and 2.4 in the gearbox.

saf-xa is a very good oil for diffs.

motul gear 300 is ok. i use redline heavy in my gearbox.

penrite syn atf in the atessa and power steer. (it dont boil)

penrite syn diff oil. sae140 gl6 awsome diff oil. does not break down like the synthetics do in a hypoid.
