Driving home from work today at 11 degrees i might add, Pull-up to a red light and in doing so hit a pot hole or Storm sewer cover, POP!!
Now i have a awesome rattling sound coming from the Driver side, can't figure out where its coming from for the life of me. Any idea's?

 

Probably sway bar links.
Same thing happened to me

 

Interesting part is, today No noise whats so ever.. Links should be ok, Just had the truck gone through back in Nov.

See if it returns.
