Squeak in front end

I have a 2015 Tundra TSS CM with a 6” lift. My front end squeaks real bad on any little bump except for when it rains. Any clue?

 

Could be many things- check lift hardware torque, all bushings like shocks, UCA, sway bar, see if shocks are seeping. Do you have aftermarket bumper or other aftermarket components added anywhere in the front? Suggest you have someone drive the truck slowly over bumpy terrain while you walk beside the truck, see if you can better pinpoint where the sound is coming from.

 

Greasable UCAs?

 

Hard to say what it could be. My advice is get a buddy and bounce the front end up and down with the one of you listening to try and pinpoint the squeak.

Had a annoying squeak and we found out it was the UCA. It was the bushings at the rear of the UCA. Sprayed them with lithium grease and the squeak went away. Spray, drive, spray and drive some more.

 

My Kings Suspension and Total Chaos UCA were installed 2 weeks ago. Squeaks at low speeds at well.

 

Are your control arm bushings urethane? Squeaking has always been the biggest knock on using urethane for suspension components.

 

^ this.

 

If you have skid plates tighten them up. If they're already tight then take them apart and check if it's rubbing on something - you'll find a worn out section if it is.
Since you have a 6" lift you most likely have a chopped and dropped crossmember. Re-torque all of the bolts that are connected to the crossmembers. I had a crack on one of my crossmembers that squeaked like a b!tch, got it fixed recently and my truck is finally quiet up front.

 

The bushings that hold the trans cooler and condenser at the top can squeak. Adjusted mine to stop, but some lube would probably work.
