What gear oils is everyone using to replace them?
I'm guessing it's:
-front diff
-transfer case
-manual trans
-rear diff
Not exactly sure what options exist (LSD vs non, etc.) in terms of "Well if you had an '01.7 TJ with the rare ABCD123 tranny 5spd then it takes Canola Oil"
am guessing synthetic 75w90 would work for everything
but I hear the trans is different from most other vehicles in that it calls for something much thinner than 75w90.
I know with German cars it usually goes like this. There's the retard who does what everyone else does, and the smart guy.
The retard, let's call him Beebo, will be like "Hurr durr Motul Gear 300 75w90" - even though that gear oil is garbage in the sense it shifts like shit even in mildly cold temps, possibly causing damage shoving that gear selector hard to try and engage a gear. But Beebo loves it because the bottle looks cool and he thinks he's a go fast racer in his slow old car due to driving to some sort of performance shop to pick up a few bottles of that rare hard to find overpriced $14/qt Trash Oil
And then you'll have the one smart guy who's like, "I noticed problems with the above oil, so I picked a different brand 75w80 that qualifies for the same part number/spec and is compatible, but has better cold shift properties."
(he picked it because it has better cold shift properties)
And then when you go to drive it after copying this smart guy and installing this oil,
you find out it has better cold shift properties.
Which matters, because on a daily commute, it takes at least 5 miles to warm up your engine oil. Even longer your trans gear oil that is thick and not heated by the burning of fuel in a combustion chamber a quick thousands of times.
So most of your shifting, is cold shifting
not "well we're trying to set a record lap time during LeMans so we've pre-heated the fluids and done 10 warm up laps in this here track car"
I am guessing the same will apply to Jeep
I will continue to search this topic for consensus. However, thought it wouldn't hurt to ask what the latest up to date opinion is.
