Hi all

I've been having this suspension noise for a while (probably since purchase).
Can anyone tell where this noise comes from? I feel it's something related to ball joint, or is there somewhere else can make this noise?

Sounds like rubber isolator. Try spraying it up with a good quality lube top to bottom.

Mine sounded similar when I didn't have my rear shock lower bolts torqued to spec after I installed shock skids.

Kind of sounds like metal scraping on metal. Noise is only coming from the rear? There are no ball joints there.
I have narrowed down to the wheel area.. I will put the axle on a jack stand tomorrow and try again, in this way the wheel does not bear load and it will tell if it's from wheel or the suspension.

Actually just did. Jack up the rear axle, and press down the rear suspension, it's silent..
Something on the wheel/axle I think...

It sounds like the control arms, when you jacked up the axle you compressed the arms past the range of the squeak. Spray a bunch of WD 40 on the bushings while you have it jacked up, then jack up the frame to let wheel droop and spray again liberally.

Don’t know if this is it or not, but it cost virtually nothing to try it.

There’s nothing at the wheel/hub area that moves on the rear axle from up and down movement of the vehicle.

perhaps the control arms need to be loosened and retightened.

I will retorque the control arms..

I'm wondering if there's a good way to properly tighten the upper control arm axle nut? It's hidden behind the wheel and almost impossible to tighten it with the wheel on ground
