Snow Covered Roads City/Highway -- 2H or 4H?

[jan123]

One thing I learned from an old 4WD mechanic when you have not used 4WD for a while, about once a month on a straight road at a moderate speed switch into 4W Hi for about a minute to move the lubrication around. Do the same with 4W Lo for a few seconds being sure to keep the truck straight and slow if the roads are dry. This just moves the lubrication around and keeps things from getting stuck. I had my Gen 3 Sport for four years and put it in 4W Lo I think two times, yes I drive highway princesses. I do use them to get to the slopes and have never worried about getting home from the mountains after skiing. I know my profile says Venice, FL, but I also have a home in PA and make many New England and PA ski trips.

The user manual on Page 406 says to drive at least 10 miles every month in 4HI to properly lubricate.

If you want to cover 10 miles and only drive in 4HI for one minute, you'd have to drive at 600 mph ;-)

Yeah - I have always done my monthly 4wd time when it rained and I was on the highway where you did not need to make any tight turns. Did that pretty regularly with my 2011 Tundra which I drove for 14 years, so I don't think that hurts anything. It is important to remember to get back into 2wd when you need to make any tighter turns or you can break stuff.

I have never bothered putting weight in the bed for better traction. It definitely works but the reason we have 4wd is to give us the traction we need when roads are slick. Any time you need more traction than rear wheel drive provides just shift into 4wd, which is easier and more economical than lugging around a lot of unnecessary weight.
