Replacement oils for 4x4 diffs in 2020
« on: February 27, 2020, 16:35:19 PM »
Hello new member here :)

I read in another thread that that we need the following for the 4x4 diffs:

Quote
Transfer box: GM oil, part number 90443530

Rear diff treat like the F28: GM oil, part number 90540998. Failing that ,fully synth 75w90.

However those are of course not made anymore. I have been given advice to buy an Opel replacement 93165260 for the transfer box (can anyone confirm this is correct?)

And we have no clues as for the replacemnet for the rear diff so would love a hint here as to vauxhall/opel replacements or anything else that would work well without killing the diff if the originals are not available.

Thanks! All help much appreciated!
