My city just got frosty and white...blah. My first winter w/the cruiser. Bought some 31" snow tires, those things are awesome!! anyways, I have the 5 speed and the in line six diesel. Can i take this thing on the highway in four high?
 
Yeah.. you should have no problem. Sure others that drive in snow more often will chime in.

Thats a sweet combo..diesel & 5speed.
 
Ofcourse!!!

We had a pretty good downfall last year here in VA. We took the 60 up to Seven Springs, PA in the middle of the blizzard with no problems. I had to stop and help lots of people get unstuck. Since the highway became a free for all (people in no appartent order, lanes, etc..) I just cruised on by via the shoulder. The highway was mostly uncleard (10-12") and I made good time in 4wd hi going about 45-50mph. My generic 33X12.5s did a really good job getting us out to some great snowboarding. Did pass a flipped jeep GC getting pulled out of a ditch on the way out there but didn't stop since there was a large gathering of on lookers and a tow truck already there.

Sorry about the rambling. I could have just said, 4wd HI is great on the snowy highway. I haven't gone beyond about 50 mph in 4 hi though.
 
I have done 70....

There really is no max speed. It is what the conditions allow..
 
Its whatever you comfortable with driving in 4wd drive without a center diff to prevent driveline windup. Personally, I think if you're able to go over 30mph, you don't need 4wd.
 
Owner's Manual says 55 mph

WORD.

My owners' manual says 55 mph MAX in 4wd. I figure if I can go 30+, I can be in 2wd. Better for gas mileage too.

I can't think of a situation where 70 mph and needing 4wd would go together.
 
You can attain speeds of up to (16ft/sec)2 - this is in free fall. Be sure you have it in fourth, tho' it will attain the same speeds in 1st or reverse.

On the road, I have no problems hitting 65 to 70 in fourth, and 75 to 80 in 5th. Snow driving is more about conditions, tires and driving technique, so you need to stay in your comfort zone, whatever the speed.

Why would 2wd be better or just as good over 30mph? Seems like that would be a good way to go from highway driving to offroading!
 
They are saying if conditions warrant 4wd you should not drive over 30.


I disagree...
 
4WD is great for accelerating but it dose nothing for braking....
If you can't brake well then you shouldn't be driving that fast. I see it all the time, that is probly how the Heep GC in the story above ended up on the roof.

When I drive in the snow I will use 4WD to get going or if the snow is real deep (2') but I will pull it out of 4WD once I am moving. The most important thing is drive slowly, if you role over you wont get there at all.

The fastest you go... the longest you will need to stop.... even in 4wd ;)

Where are you in Canada ?
 
leaving it in 4H while on snowy roads can keep you out of trouble and help get you out of it quickly, even at highway speeds. driving at too high a speed while the hubs are engaged can lead to hub failure but you've got to be "pushing it" for an extended period of time. good rule of thumb to follow is to keep your speed below 60 mph max.

if the roads are patchy or dry, definitely disengage the hubs and drive in 2H. otherwise, leave the hubs engaged, drive in 2H while applying the max speed rule, and engage 4H on an as need basis. this will keep the front wheels turning with the axles which helps a little bit on the traction and gas mileage front.

When it's snowy don't be afraid to use 4WD though! I've heard of folks being reluctant to use 4WD because it was a snow covered paved road!

No offense but bull.

The locking hubs themselves are stationary when locked. They litterally have no moving parts.

The axle hub always spins any way.....
 
Wait. Is it safe to just leave the hubs locked during the winter? The roads around here are patchy in that some are snow covered and some are heavily salted. I run 4WD when necessary and in 2H with the hubs locked at all other tiimes.

I thought that I read that it was safe, but I just want to make sure
 
thanks for all the opinions guys, i appreciate the feedback. I consider myself a decent driver, but sometimes the road condtions in alberta during the winter are really crappy. 4-high helps with black ice and heavy snow in my opinion, even at higher speeds. This situation would be the exception of course. I just didn't want to burn out my t-case or something frustrating like that.

oh yeah, i read a quote one time: "the only thing that all people have in common
is that everybody thinks they're an above
average driver"

Yep..


Lubricates things actually..

If you never throw your truck in 4wd it is a good idea to drive around with the hubs locked sometimes.
