    Redline Shockproof Heavy Gear Oil. It is a full synthetic. It is kinda pricey but it has worked great for me.

    That is the best stuff you can put in a diff. It has such a high PSI rating its like the teeth dont even come in contact with eachother.

    What's the difference between 90 grade and 140 grade gear oil?

    I was once told that 140 is better for older gears...

    90 weight is much thiner that 140. 90w at 40 degrees is about what 140 is a 80 degrees. 140 is more or less a greese at freezing. I would avoid using it in anything other than farm equipment or extream summer heat in a diff.

    I've always used Redline or Amsoil products. I like Amsoils motor oils better than Redline, but in trannys and diffs I always use Redline. Makes a tranny shift like butter is in there. Like they say.....you get what you pay for. My .02.

    thick is better!

    I like using 85w/140 gear lube in leaky transfer cases and rear ends..it leaks out slower,and all of mine have 100,000 plus miles on them,so there is plenty of clearence for thicker oil..in something that doesn't leak,or a standard transmission,I'd use 80w90 or whatever else the book says too--

    I tried using 85w140 in a SM465 I had that was noisy,along with a can of STP..it was nice and quiet,but when winter came and it got below 30 degrees,I nearly broke the shifter off trying to get it in gear first thing in the morning!..had to put 80w90 back in.. :doah: :crazy:

    I don't get into any water crossings so I use Mobil full synthetic or Valvoline DuraBlend semi synthetic.

    If you are mudding or 4x4 or towing boats where you are submerging the diff you need to change the fluid often, and if that was the case for me I would just buy the coastal lube by the gallon.

    I run the royal purple in everything. Trans,doubler,axles,engine and love it. I would recommend it to anybody. It is a little pricey but worth it.

    Regular parts store 85/140 upfront where its open and hardly used . Redline Shockproof heavy out back with the locker , on Harleys advice . He was right too , you start thinking of dimes and quarters if ya see a drip :D

    Looking at where he's living, 140 might work good.

    I usually run Vavoline 80/90 Durablend. I like using synthetic.

    I may switch to that Red Line stuff though. Sounds like the stuff.
