Front end clunking and buzzing noise during extreme cold
Been fairly cold here the past few days, yesterday was -26C/-15F and my truck sat at the office for a few hours in the morning and again in the afternoon. When I drove it home for lunch it started making a buzzing noise that sounded just like the mudflaps were caught in the tires, I stopped right away before I ripped off the mudflaps and walked around the truck...nothing, mudflaps weren't the problem. So I started driving again and same thing but add in some fierce clunking noises from the front end...exact same clunk that the 4x4 makes when it shifts in hard, did about 3 or 4 quick clunks and then it all stopped after 2 minute of driving. On the drive home for supper, same thing happened. This morning, again it's pretty cold -26C/-15F, exact same thing and then it stops after a minute or two.
The other weird cold weather noise I've heard is a popping noise coming from behind me, sounds like the frame is shifting like a huge load is in the back but the truck is empty, happens going up or down logging roads...doesn't happen that much but it's a loud pop when it does occur.
