Ok...so how do I not tear up my transfer case in the Colorado snow?
I took the beast on its maiden voyage in the snow this morning and it did fine in two wheel drive. Though the defroster could work a little better! I figured that would be an issue. So is fogging on the inside of the truck cab, but anyway, the drive got me thinking. Its a '76 250 with the part time transfer case in it. I have just recently found out I am transferring locations for work and I'm going to have to drive quite a bit farther for work. Two questions. One...how fast can I go with four-wheel engaged? Also, how am I going to deal with the patchy snow/ice then dry pavement issue we seem to have in the Denver metro area? Am I going to have to pull over between each patch and put it in two-wheel, then stop and put it in four-wheel and keep going with the pattern? Or can I just drive with it in four-wheel and hope the pavement isn't just wet or dry for too long? Just some things I have been wondering about!
1 - Speed should be kept at 40MPH or less. There are alot of people that will say, "I can do 60", 'I can do 70!"...Manufacturer suggests 40 or less. I have run mine at 45 but then take it out of 4x4. If I am going that fast, then 2WD will work fine.
2 - Being that it is a 76, I am going to assume that you have the manual hubs. What I have done every winter, if snow is in the forecast, as soon as it gets close to being a prob, I lock my hubs in and leave em that way. I then switch in and out of 4x4 as needed. You can go from 4wd to 2wd and back on the fly. Just be at lower speeds when you do. Less stress on the drive train. Going in and out of 4wd Low, you need to be stopped and in neutral. I only keep the hubs locked in when there is alot of snow on the ground. With the all terrain tires, I can get around pretty good without 4wd. I usually only use it at starting from a light to keep from spinning alot then go to 2wd after I am moving, or when I am pulling a car out of the ditch.
Now of course, this was when I had my Bronco. I'm looking for another.
