Gear oil question

The other day when I tried to pull a car out of the snow when the strap snapped (another thread on that) I noticed in the snow under the car what appeared to be some gear oil. I have not crawled under the car to check but could I have caused gear oil to vent out of the rear end? I did a lot of rocking back and forth to get the car unstuck and thought maybe this caused the oil to vent. Did not look like a lot but enough for me to notice. Does the rear end have a vent on it where this could happen? Also does the rear end use synthetic 75w140 oil? Thx

I don't know about the rear end but the PTU does have a vent.  The first time I drove my SHO really hard, I had a few drops over night.  I freaked out but was assured that it was normal.

What kind of oil does the PTU use?

Sounds right.  I wasn't sure.

Probably was the PTU now that I think about it. Looks like a bit$h to add some or check.

No the differential uses a different weight..maybe 75w90? I am not sure of that, but I do know it is NOT the same as the PTU.

Thanks... I think it was the PTU that puked and I'll check tomorrow and top it off if needed. I guess just make sure the level is up to the fill hole.

Just an update. The rear end does have a vent towards the top of the differential housing and this is where the gear oil puked a few ounces the other day. I pulled the plug and topped it off with the same amount I lost. I was at a slight incline when I was pulling the car out of the snow and that's probably why it burped some.

Interesting.  Glad you found it!

Any inputs on this oil? I've never used it but walking the isles at Napa and saw it was extremely expensive so I figured maybe it's good... Anyone ever heard of it or used it ?
It's $70 bucks for that small bottle.

What is it made out of Gold! LOl
I have always used Redline 75w-140 GL-5 Gear oil which meets,exceeds GL-5 OEM Specs!   
I ordered a couple of quarts from www.amazon.com for roughly $15.00 ea .IIRC! 
IMO would stick with Redline or Amsoil especially for the PTU,RDU. Z
