Hello everybody, I have a 2014 Navara Diesel D40 and I thought I would engage 4wd this morning as roads were very icy here in Uk. I drove it for a mile or two and noticed a slight burning smell which when i got out to have a look seemed to come from the front on the drivers side. Could anyone suggest what the problem might be? Is it simply where i have been using on tarmac rather than mud etc? Thank you in advance, Amy. PS it does tend to stick in 4wd when I change back to 2wd but if i put in reverse that normally sorts it out!
