Diff fluid change

[VXR]

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!
