Old AWD vs New AWD


Recommended Posts

Posted

So I've been searching a lot and researching 4wd and awd systems. I currently have a 99 silverado and am familiar with how that 4wd system works. I'm looking to upgrade to something newer, possibly with AWD. From what I can tell, the NVG-149 viscous coupling style is better than the BW-4481 open diff style; like on 08+ denalis. I have a basic understand of how both systems work but can someone enlighten me on why the viscous coupling system, or what about the older awd, like on the Silverado SS, is better in snow than the newer denalis?

The viscous coupling allows for some degree of lock up, similar to 4-high on a normal truck. The new system has an open differential in the transfer case so it could allow 100% of the power to an axle with no traction. There are electronics to help with this but it in no way is as good as the mechanical system.

I believe mechanical systems have less of chance to go wrong. I.e mis communicating, shorting , or just corrosion can screw with the system. If you PM anything it will work well. But I agree with MikeNH

I have a 2012 AWD Denali and its very good in snow. Better than any 4x4 truck I ever owned and I've owned a few (89,92,96,99,01,04,08,10). 99% of the time you don't even realize you are driving an AWD vehicle. Quiet and trouble free in 23,000 miles. Only thing I ever did was get rid of the low bidder ATF right away for 100% synthetic ATF (Dexron VI req'd).

 

If you put 2 trucks in front of me, one 4x4 and one AWD I would take AWD without hesitation even if it costs more. I also have a 2009 Cadillac CTS with AWD. The car feels like its on rails.

    • This is the 6.6 gasser section of the forum, you should either delete or modify your previous post as it is misleading for anyone looking for factual information on their 6.6 gas engine.
    • Well....I've done my first intake gasket. Probably wrong, but...we'll see?   Ultra black on the china walls and 1/4" up onto the sides of the intake gaskets. Permatex High Tack (couldn't find Gaskachinch) on the head side of the intake gasket. I read wrong and it says you're supposed to put it on the mating surface of the head, not the gasket. Hoping it's like a PB&J sandwich where it doesn't matter what side the PB goes on so long as there's jelly. That crap is messy/sticky and I got a dab or two on the intake port openings, tried to wipe it off. Hopefully it won't be a big deal and will only aid in sealing.   Per instructions I left the intake (top side) of the gasket dry except for a light smear of RTV around the coolant ports. Wiggling the intake in there was a bear but I had help to free me of surrounding wiring/stuff but I was basically able to set it straight down lined up with the bolt holes.   I did not think to wait until the RTV skinned over but there probably was 5-10 minutes while it sat before installing the intake.   Bolts finger tight first. Then, followed the Chilton's manual pattern to snug them to 15 lb-ft.   Waited a little over an hour, and then did the final torque in sequence again to 35 lb-ft.   Yesterday I replaced the fuel pressure regulator and got my new "nut and bolt kit" (fuel lines) installed. Damn GM used security torx on the spider, which I don't have, so I got scammed at the local HW store for an off-brand security Torx bit set.   The new driver's door mirror arrived yesterday, so, there's a chance this thing could be running and road legal tomorrow? I don't want to get my hopes up.   This will be my first time stabbing a distributor, too. Although, lucky me, someone else marked the old distributor for removal previously, I did see that. (Someone's been here before!!). Engine is still at TDC so it *should* be just a matter of transferring the mark to the new dizzy and rotating it into place.
    • He has his dad’s newer truck he’s put away. He has several old cars he rotates between him and his family. I’ve seen a restored square body and a SS Chevy truck he’s sometimes drives. He did raffle off a new suburban recently. As much as he is watched if he drove new stuff as a rule we’d know it. It would be fine by me. I don’t care what people prefer. I got one more new one in me. I’d rather my wife get one. I can’t get her out of the Genesis. Don’t tell anyone. I want her to get an electric truck. I want to put a generator in the back. Just because. She hasn’t bit yet.
    • Yes, you must have seen my thread on the Blazer. HOT GARBAGE, but I love them anyway. I'm convinced every car guy has a soft sport for an S/T series somewheres. Probably even a Panther too, if I'm being an honest car guy. That doesn't mean they aren't junk. And they definitely don't get better with age. I sometimes play with old cars, but that's by choice. I don't rely on them and they aren't my everyday fleet.   Derek plays the common man on Youtube and that's no doubt where he started. Now he has Youtube money (and Motortrend, etc). You think his crews and his wife ride around in old beaters when they're chasing him and his wrecks across the country? No he's got newer and nicer stuff for that, you'll see glimpses of it in the footage.
    • You refuse to own anything made in this century yet you reportedly own... a 2007 Silverado, which is now almost 20 years old. The dissonance.... turn up your hearing aid?   You clearly don't understand the government contracting process, brother. We send people to die on front lines, keep the public safe, and make people's husbands, wives, children enter burning buildings with equipment from .....wait for it.....   ...the lowest bidder....   Just because something is used for a long time doesn't mean it's good. But it might be cheap and plentiful.   Please, continue to whine about new trucks in a thread dedicated to new trucks, which you've said you'll never own. We get it. Go tell everyone how you're stuck in time on a Panther forum. I mean, Jesus, an 86 isn't even one of the good Panthers.
