Suspension creaking noise.

Driving home tonight and heard my suspension creaking. I don't know much about suspension.
It's been cold here in Denver the past couple weeks and with the snow there's lots of sand/gravel being laid down for traction. Was going to take a look at it tomorrow to see if I can see anything out of the ordinary. Also going to the carwash to wash them off to see if that helps.
What else could this be from or what should I be looking for that would be a bad sign? Any help or insight is appreciated.

 

What suspension upgrades do you have? Can you tell if the noise is coming from the front or rear?
Car wash the front and rear suspension components and test drive again.

 

No suspension upgrades. It coming from the front. Going to wash everything. Would it hurt to spray silicone lubricant in the bushings?

 

Yes, do not spray lube of any kind!

I bet that the front cab mount bushings https://www.tacomaworld.com/threads/front-body-mount-squeak.782395/#post-27996435

 

Cool. Thank you for the reply. Will check out that post.
