Convert tahoe to AWD

[grayhoe00]

yes but we have to be sneaky about it because they look like they would kick us and the one on the right is a golden gloves boxer

mmmmmmmmmmmmmm even hotter!!!

AWD is basically RWD that kicks into 4H when needed. You have no control over it.

The 4WD versions allow you to select 2WD, Auto (AWD), 4H, and 4L manually. I use a Tahoe off road in sand and mud almost every day at work. I promise you that there is a HUGE difference between Auto (AWD) and 4H/L.

i thought awd drive spun all the the time.

It's different I just can't remember exactly how off hand. Somebody should buy it so I don't keep getting crazy ideas in my head.

I could be wrong. It's happened once before.

how ever it works i love it on my audi when the weather sucks!

I guess it depends on the AWD system.

Here's what I found:

All wheel drive (AWD) is almost the same thing as full time 4WD - it is a system that powers all four wheels of a vehicle at all times as well. It can be used full time on all surfaces including pavement like full time 4WD. Difference to full time 4WD is that a "4-low" setting is not available in AWD cars. Due to the lack of "low range", AWD vehicles are much less capable in off-road settings than full time 4WD vehicles, but work perfectly well on-road.

Automatic AWD system is the newest kid on the block. PR agency generated names like "Real Time 4WD", "intelligent AWD" or "active AWD" are hiding the fact that automatic AWD is essentially a sophisticated 2WD system. Automatic AWD is NOT powering all 4 wheels all the time. Only on rare occasions all 4 wheels will be powered very briefly. Since AWD is only engaged on rare occasions, sometimes automatic AWD is falsely called "part time 4WD". Engineers refer to this system as an "on demand system". Since it is based on an existing 2WD steup, it is also referred to as a "hang on" solution.

The latter is how the AWD in my buddy's CTS works.

AWD just depends on the system. Usually they have a front or rear bias and, depending on the system, can send power to individual wheels as needed or to the front or rear axles as needed. The major difference between 4WD and AWD is that AWD always has all 4 wheels receiving some amount of power, even if it's negligible. I know some higher end exotics can send up to 95% of the engines power to the front or rear axles depending on traction while most cars see something more like a 60/40 split or 80/20 with the ability to go 50/50 and even 20/80 as needed.

I believe this is how the "4 AUTO" feature is suppose to work in our trucks. Am I wrong?

No it stays in 4wd until the rear starts to slip

Then what?
