Took the Sierra out in the snow to see how she handles in it / how the A4WD kicks in (we're supposed to get 12" here, but I don't think it's going to be quite that much, based on what I've seen so far).
Anyway... I was pleasantly surprised with the A4WD - it's not a 'slip-bang' system like in the 360s. I can feel when it kicks in (and out) - but I have to be focusing on it. It's subtle, by comparison.
I could hear one of my front hubs (the one I didn't replace) howling a bit - I probably should've replaced it when I had the LH side axle apart recently to fix the diff leak there. It'll last until spring without getting much louder (fingers crossed). It's making noise intermittently now, so I probably have awhile.
The other thing I heard was a lot of popping / bumping - and since I've got a brand-new suspension all the way around, I figure that with its age / mileage, I probably need to replace the body mounts (isolators) all around. First, I'll get back underneath and inspect them before ordering new ones - it would be a royal PITA to order first, and then discover that one or more couldn't be replaced due to corrosion issues.
Was wondering if anyone had done this before (on a 360 / 800 / 900 / etc.) Searched our forums and didn't see any hits on 'replace body mount'. External sites range from 'stupid easy' to 'be careful, else you'll lose fingers'. Looking to see what YT has on it, video-wise.
