I'm the proud owner of a 2010 Tacoma ext. cab and looking for some advice. I've been reading the owner's manual and came across a section in the manual where it states the truck should be driven in 4 wheel drive at least 10 miles a month to keep everything lubricated. I was always under the impression not to drive a vehicle in 4 wheel drive on dry pavement. Once winter gets here I'll have more than enough time to drive in 4 wheel, but until then curious what to do. Thanks.
