| Max. weight for synthetic t-case gear oil?
Anyone know how thick you can go with synthetic in your t-case? I'd like to try queiting my gears a bit but don't want to do any damage...
Thanks,
Tim

| I've heard that Redline Gear Oil is great for transfer cases...esp ones that are worn. Is your's leaking? Why are you thinking of going thicker?

| 75-140 is about as heavy as it gets, AFAIK, Tim. Those Mark's gears a little noisey, are they?

| What have you been using ? Is it conditioned for limited slip applications ?
IMO, going heavier will yield marginal results. You need better quality oil. I did some experimenting using convertional mineral base and then switching to a conventional mineral base with limited slip conditioner.
Note: The limited slip conditioner was already in the oil.
Took the noise down a definite notch. Not quiet ... to hear a pin drop, but definitely an improvement.
Somebody else wil have to comment on the synthetics. I'm not a fan of running synthetics in our trucks in *general* unless there is a *specific* reason.

| Ahhh, so it's because of the Marks gears...
Instead of changing the oil, why not use some noise abatement materials on the floor?

| Out of town or would have replied earlier: yes, it's the Mark's Gears. Not horribly loud but wouldn't mind quiting them a bit. Sounds now EXACTLY like a worn t-case gear whine (at least exactly like my brother's fj62 t-case sounds. Someday when I move to the Great Interior Makeover (pull out cargo drawers, decent stereo, etc.) I will add more sound proofing to the truck as well. But I heard that thicker synthetic gear oil will make the t-case a bit quieter than plain ol' 90wt...
