What do I use?

[P1E]

I need some advice on the following. Car is an R33 GTS-25t.

1. I have been told I need to replace my diff oil. What do you all use and recommend? Also, what exactly is a diff? Where in the car is it? How do you change it? Etc, etc.

2. I need to top up my power steering fluid as it has been leaking. Again, what do you all use and recommend?

The dif in your 33 is where the rar axle meats the tail shaft. It converts the engines rotation (and power) through 90 degrees and out to the rear wheels.

Ah, makes sense.

What oil should I use?

[4door_Sleeper]

Not sure which oil you should use, why not ring Tillbroks, Morepowa etc and ask what they recommend. (I would stay away from the cheep oils at most car parts stores)

For the diff, use a Castrol or Penrite 80w/90 (or similar) Gear Oil. Ask your local Autobarn or Repco. Frankly, filling the diff is a pig of a job unless you have some sort of gun. Better on the nerves to pay someone to do it for you.

Steering - Auto Trans fluid does the trick.

There is a tread floating about somewhere on how to do it yourself. It is a bit of a bitch really. From memory i used a castrol 80/90w...
