    Yes I did and I changed the fluid and it definitely made a "diff"erence ...lol Sorry i couldn't resist. But yeah, I flashed back to when I was installing all the new frontend stuff and for whatever reason, probably tired, I didn't drain the diff I just topped it off with additional fluid. So yesterday I drained it, douched it out with some new fluid a bit and cleaned it real good. The fluid was nasty black, don't know what I was thinking not doing it right the first time. Good news is it's nice and fresh and it no longer feels like I have the brakes on. I'm thinking it may improve mpg a tad. What's weird is my H3 with the Adventure package gets 16 mpg regardless of what I'm doing, even pulling a trailer. The base model, daily driver only gets 12 if that. We'll see what happens as I'm in the midst of adding new bells and whistles in hopes to get it top notch.

    Yes I did, I thought I replied to this already but I don't see it so here we go. Yes I changed the front diff, back and tranny fluid the other day and it made a big "diff"erence. I'm going change the Transfer case tonight just so it's all good. You may not believe this but changing the fluids in all of the listed increased my gas mileage by 2 mpgs!!! Can you believe that...freakin' awesome. I was wondering why my other Hummer gets 16 mpg and this one only got 12 mpg. Now its up to 14 mpg. So it was well worth it.
