One cause of a popping noise from the front end while backing up in cold weather is the drive shaft. A mechanic can help find the problem.
could be a contant velocity joint

you probably need a cv joint
If it is front wheel drive is can be a bad CV joint but you should hear a popping noise if that is the case.

To burst a balloon without a popping sound, you can slowly release the air while applying increasing pressure on the balloon's surface. Alternatively, you can use a sharp object to create a small hole in the balloon and allow the air to escape gradually, avoiding a loud noise.
Your CV joints or axles are probably going bad. You should probably take your car into a local mechanic to have it checked out.
Likely a loose or broken strut or shock. Could be the same for a load leveling bar, depending on the vehicle.
Pops while moving but probably not when sitting still and just turning the wheel? One or both of the axles has a torn boot and the CV joint is going bad. Front wheel drive I assume.
