Diff fluid change

[LittleBeast]

Yeah 6 sided socket (make sure it is in mm), soak in PB Blaster, and then use a breaker bar (extension tube). And I don't want to scare you or anything but I have experienced better performance, and longer life with normal dino tranny fluid and diff fluid than synthetic stuff, don't know why doesn't really make sense to me, all I know is I have heard of more tranny's burning out after synthetic switch, and more issues in diff's after going to synthetic than those who stay with the normal (recommended stuff). Maybe it is due to not getting level correct or maybe it is due to synthetic leaking more, I am not sure, but that has just been my experience with the VX and making observations from who is having what problems on here. Just a little 2 cents, and know I will be sticking with the cheaper (recommended) fluids, except on the engine, always have gone synthetic there ;-)

Where have you heard this

I sure hope not I just switched to mobil 1 ATF and diff fluid last year

I think the rational behind this is that synthetics clean better, and could possible break up any buildup and that would cause a problem.......

I did it at under 40k and did the filter too so should be ok

Fyi, im pretty sure the vx diffs are aluminum (i know the plugs are). You really should never have to tighten a fill plug that much, its pretty much there to keep fluids from splashing out and keep dirt from getting in. for some reason people commonly over tighten fill plugs, theres no reason for it. Just hand tighten with a short rachet, thats all it needs. Snug it, then add that little tiny bit past that.

I think you're thinking of the transfer case Jack, the F&R diffs are steel.

Can I use 75W - 140 in both front and rear or should I use 75W-140 in the rear and 75W-90 in the front? I used the two different weights when I did it last time.

Thanks for the help!
