Rear end squeak.

Hi guys,

I’ve noticed while out in the bush today that my rear end on my 09 Silverado 1500 is sqeauking, when I got home I narrowed it down to either a u joint or differential input seal. It’s currently close to -15c with wind chill and it only does this when it’s cold. Just wondering if anyone has had this happen or could the axle seals be cold enough to shrink and squeak.

Thanks
