2021 SR5 with a really loud squeak in rear

I have a 2021 SR5 (13K miles) that started developing a squeak when going over bumps. The squeaking started some time back but was not very noticeable. Over the last couple of months the squeaking has gotten louder and can be heard just driving down the road (all the time). When pushing down on the truck I notices that it is coming from the rear somewhere. Just a little pushing and it is very noticeable.

I'm taking into the dealership tomorrow to see if they can identify where it is coming from and fix it. But I'm wondering if anyone else with a newer truck has this same issue in the rear of their truck?

 

Probably the leafs. Jack the truck on something other than the axle to decompress the leaf pack, take a pry bar to spread the leafs and lube the leaf puck with white lithium moly grease. Repeat for all the leaf pucks.

Although since yours is so new, take it to dealer.

 

Took it to the dealer this morning. I was the leaf springs. They said the pads were "dried out" and they lubricated them. Squeaking has stopped...for now. I'm assuming it will return at some point when the lube they applied wears out?

 

Yeah, depending on how much weather you get or how much offloading you do, probably somewhere between 1 to 5 years.

Luckily it's a real easy job, and if you've done it once, it takes like 15mins. The hardest thing is finding a good jacking point. I jacked up mine by the trailer hitch mount.
