Diff

[defari]

did my diff oil today, not too much problem, bolts were fairly easy to take off..

Read somewhere that the diff takes about 1.9 - 2L.. I had the car on level ground with a hand pump siphon but could only manage to get about 1.5L. I tried pumping more in but it was dibbling out quicker than i could get it in.

Should it still be ok?

[turboedsloth]

if its dribbling out like that then it should be fine

it takes 1.5lt

[defari]

sweet, cheers.

what diff oil did you use? i was looking at doing mine soon.

Yep it takes about 1.5 - as long as it continues to come out after you've pumped it in then you're sweet

Use an 80w90 for a mostly street-driven vehicle, and circa 85w140 for a track car. Does not need to be LSD fluid for a standard viscous GTS-T diff.

used castrol SAF-XA rear axel diff oil 80w90, took about 1.5L

get a hand siphon off ebay its like 10 bucks, it saves soooooooooooooo much time.

birds - yep it was coming out quicker than i could pump it in so figured it was full

havent really found much difference doing the diff oil - it doesnt shudder as much if anything

You probably won't notice much, it's not much of a human interaction device like the gearbox where you can feel through your hand the difference between different oils and fresh/old. Also, diff and gearbox oil can last a long time as it is not exposed to much in the way of contamination like engine oil is. Were you just doing a service interval change or were you trying to fix a diff problem?

[defari]

just a service. Had no idea when it was last done / ever done by previous owners. Got all the oils cheap too.

The GB oil change though has made a difference, although the gb never crunched etc, i did it for the same reason as the diff (wasn't sure when it was last done) The gearbox was getting a bit "whiny" in the first 5mins of driving in the morning - the whining noise is somewhat gone but can still hear it slightly however i noticed the car wasnt as jerky when i was getting on/off the gas. Also the gears just felt more "solid".

to assuming nothing had been done. did the same on mine, changed all the oils soon after getting it. makes a definite difference overall. although im not happy with the Penrite gearbox oil

had a charade that was serviced by a reputable shop and the gearbox eventually died, the old fluid came out "like water" the mech told me so it was way past its service interval.

i do my gearbox and diff oil every 40k km, which is what the service manual states
