Thoughts on a 2010 Sierra Denali


Recommended Posts

Im in the market for a different truck, looking at a Denali. Truck has a 6.2l and a 6speed. What makes me nervous is the AWD, is this going to be an issue bombing around the lake with chains on pulling a wheel house. How is it going to pull my 8.5'/16' wheel house? Will the 6speed make up for the 3.42 gears?

I guess its not so much the AWD im worried about, my concern is this transfer case is designed for on road street use not off road lake use. There is no Low range in the transfer case but im not real concerned about that since I cant remember the last time I used Low range.

I have the Yukon XL variation of this powertrain. Absolutely love the 6.2L engine. The power seems limitless.

Regarding the 6 spd tranny and the 3.42 gears I think the 6 spd makes up for the taller gearing.

I have a 19' boat that I pull to Canada every summer. It pulls the boat magnificent. If I keep my speeds down to around 65 I get 16mpg pulling the boat. If I go over that it drops to like 13 or 14.

I rarely use tow/haul mode.

Not sure if AWD would help/hinder your offroad travels on the ice. I would think it would be great considering some of those Subarus you see driving around LOW with tracks on, but I haven't really Baja 1000'd with it. I don't think it would do real well pulling stumps out of the ground or guys out of the ditch, but otherwise I think it would be fine.

If I drive reasonable not towing I have gotten over 20MPG. By reasonable I mean around 65. It surprised me a bit because I didn't expect it to be that great considering how terrible the 6.0 is on gas, but this is clearly much more efficient.

    • By The way that didn't work either!! Screw it I'll just use the cellular. 
    • It’s done automatically.  You might need an actual person to clear that log in stuff up.   Trash your laptop history if you haven’t tried that already.
    • 😂 yea pretty amazing how b o o b i e s gets flagged, but they can't respond or tell me why I  can't get logged in here on my laptop but I can on my cellular  😪
    • I grilled some brats yesterday, maybe next weekend will the next round...  
    • You got word censored cuz you said        B o o b ies….. haha.   Yeah, no… grilling is on hiatus for a bit.
    • Chicken mine,  melded in Mccormick poultry seasoning for 24 hours.  Grill will get a break till the frigid temps go away!
    • we had some nice weather yesterday and this conundrum was driving me crazy  so I drove up to the house to take another look. I got a bunch of goodies via ups yesterday (cables,  winch ratchet parts, handles, leaf springs etc).   I wanted to make sure the new leaf springs I got fit. I got everything laid out and ready to go. Will be busy this weekend with kids stuff and too cold to fish anyway, but I will try to get back up there again next weekend and get it done. I don't think it will be bad once I get it lifted up.    For anyone in the google verse, the leaf springs are 4 leafs and measure 25 1/4" eye  to eye per Yetti. I didnt want to pay their markup so just got something else comparable rated for the same weight.   I am a first time wheel house owner, this is all new to me. My house didn't come with any handles for the rear cables? I was told this week by someone in the industry that cordless drills do not have enough brake to lower it slow enough and it can damage the cables and the ratchets in the winches.  I put on a handle last night and it is 100% better than using a drill, unfortatenly I found out the hard way lol and will only use the ICNutz to raise the house now.
    • I haven’t done any leaf springs for a long time and I can’t completely see the connections in your pics BUT I I’d be rounding up: PB Blaster, torch, 3 lb hammer, chisel, cut off tool, breaker bar, Jack stands or blocks.   This kind of stuff usually isn’t the easiest.   I would think you would be able to get at what you need by keeping the house up with Jack stands and getting the pressure off that suspension, then attack the hardware.  But again, I don’t feel like I can see everything going on there.
    • reviving an old thread due to running into the same issue with the same year of house. not expecting anything from yetti and I already have replacement parts ordered and on the way.   I am looking for some input or feedback on how to replace the leaf springs themselves.    If I jack the house up and remove the tire, is it possible to pivot the axel assembly low enough to get to the other end of the leaf spring and remove that one bolt?   Or do I have to remove the entire pivot arm to get to it? Then I also have to factor in brake wire as well then. What a mess   My house is currently an hour away from my home at a relatives, going to go back up and look it over again and try to figure out a game plan.           Above pic is with house lowered on ice, the other end of that leaf is what I need to get to.   above pic is side that middle bolt broke and bottom 2 leafs fell out here is other side that didnt break but you can see bottom half of leaf already did but atleast bolt is still in there here is hub assembly in my garage with house lowered and tires off when I put new tires on it a couple months ago. hopefully I can raise house high enough that it can drop down far enough and not snap brake cable there so I can get to that other end of the leaf spring.
