PTU and rear Diff fluid for VXR

[1qazwsx4]

I asked my dealer today who told me that they haven't actually done it before for a VXR and couldn't tell me what fluids were being used - they would look into it for me.

I have checked out the Buick forums and there's a mixed bag of answers.

Just wondered if anyone here has done theirs and what did they use?

Cheers

Ebbett Hamilton replaced my RDU and did a fluid flush, my car was recalled so it's something they will have performed a few times.

RDU? What was your car recalled for? I got some part numbers from my local dealer...
93165388 for the diff approx $70 NZD
19419206 for the PTU approx $500 NZD

Yeah... Not sure what the story is with the PTU oil price, I've read a few stories of these both being dramatic on what oil they take - I usually prefer aftermarket for better quality fluids but I can't find any alternatives that suit

Turns out it wasn't recalled, I must have got it mixed up with my Hyundai i30 that was recalled, twice.

So on talking to another dealer they told me that for the rear diff they use any high quality GL-5 75w90 with LS

And for the PTU they said the same GL-5 75w90 without LS would be fine... However finding one without LS seems difficult.

Went to service mine and found this mess at the rear diff. Brought the car 3 months ago the company gave it a new wof for me. Think this has happened in three months?
