Yes, Redline will take my return and send me this. I can't believe Jeep didn't send me a new manual with the CORRECT axle fluid, or at least a note with the correction. If it wasn't for this forum I would've put the wrong one in. I doubt it would've caused any immediate damage, but I bet it would have long term. Both 80 and 90 are very similar per Redline's support but they will be sending me 75W85 GL-5.
Thank you guys.
