We had a pretty decent snowfall here in the last 2 weeks and it's been below freezing for most days. I noticed a loud poping/ banging sound (pretty sure it's not subframe bushings I know what those sound like when loose  ) coming from underneath my truck. I do not see/ feel anything loose. The only thing that I can think of is maybe water getting between the leaf springs, freezing between the leafs, and then poping loose as the spring flexes?
Has anyone else experienced this? Am I nuts (wait don't answer that ) ?

Is it happening when you brake, accellerate, or anytime while driving?
With it that cold, your driveshaft may be a little shorter, and could be clunking back and forth on the spline as you brake or accellerate. The fix is to grease it, believe it or not. Mine is newer, so it has not needed greasing yet, but it is due soon. There are other posts on this issue somewhere around here. |

hmm didn't think to check the drive shafts. Thanks for the suggsetion. It does seem to happen when accelerating but mostly when I'm turning at the same time. My truck is in the shop right now - will have to take a look when I get it back.

You need to check your front swaybar bushings and end links. If they are bad, a clunking like you describe can also occur. Check your spring bushings to make sure they are not worn out or out of place.
I know this is sounds silly, but check to make sure the hubs are in the automatic mode, the dash switch is in 2WD, and that the front driveshaft is not moving when the car is going. If the front hubs are locking in and running in 4WD you can hear some oddball clunks. |

Mine had snow and ice packed between rear bumper and wheel wells for more than a month. I finally took it up to the quarter car wash and cleaned it up. I have been getting a clunk in the rear over bumps, but still have it. I thought the rear shocks were loose but they were OK. It seems the colder it gets the louder the clunk. I general cold weather will make the suspension louder but I'm getting sick of this. Just have to wait for a 40 degree day and check it out further. |

Mine does that also when it is very cold. There could be ice in the leaf's. I never did check it out though. For the rest of you this noise is after the truck sits and is not moving. Useally after sitting overnight. We had the recent cold spell and it was about 10 degrees above zero in the garage. each time you step into the truck it would clunk and pop.

During the winter I hit the leaf spring separating pads with some lubricating spray which helps reduce the squeeking,clunking.
