So I was driving around when I started to notice a clunking sound coming from the front of my 2019 4runner on the passenger side. I only have about 7000 miles on the 4Runner and I had kings installed about 3 week ago. I am planning to take it back to the shop if it’s something serious. Hoping it’s something I can easily fix myself, but I can’t seem to figure out where it’s coming from. Left my phone under the car recording while I rocked it back and forth standing on the slider. Any idea what this could be? Here is the video:

Your vehicle is fully under warranty take it to the shop because any help here would be endless speculation

No idea but that would drive me crazy!

Are you running aftermarket control arms? I had the older SPC arms with the older bushing where the cross bolt goes through, makes the same noise after a while because the inside of the bushing was dried.

I’d go back to the shop and have them go over everything and make sure it’s all torqued properly. That would make me lose my mind

Yes, I’m running Icon tubular UCAs.

Like the post above yours, I'd have the shop torque the bolt as well.

I had an annoying pop like that. My solution was to remove my Icon UCA’s remove the bushings, re-grease them and the sleeves and reinstall. I also found the zerks in the UCA were clogged which was the cause for the rebuild anyway. I did not need to remove the upper ball joint to do this but I have ICON Deltas.

Reassemble and torque to 85ft#s.

The tear down took me about 30 min a side. You need a set of 19mm.

make sure to check the LCA bolts. IF you had an alignment done afterward, it's possible they weren't torqued to 129 ft-lb.

Otherwise, I also had a clunk similar to that on the driverside that was a real bugger to track down. wound up being a slider bolt.
...Where you just had a new suspension installed, I'd probably start with the LCA bolts and then move to the UCA. If you jack it up enough to get a long wrecking bar under the tire and then lift the tire up and down (use 2 jackstands) you might be able to get a better idea of what's making the noise.
Likewise, if you can get under the truck while someone else rocks it, you can put your hands on things are that really helps to track down noises. You should be able to recreate it by opening the door and pushing up on the door jamb at the roof, if you don't want to jump up and down on the sliders for one reason or another.

Of course, the big problem with that type of clunk is that it will sound like its coming from the UCA when you are looking at that, and the LCA when you are underneath.

Please post back when you get this solved. Good luck!

Thanks for the tips! I had my gf jump up and on the slider to see if I could find it. I started from underneath the front of the car and chased it all the way around out the side and then back under again haha. It sounded as if it kept moving around. I will check the UCA and LCA bolts and try greasing the UCA bushings. Hopefully I’ll have positive news to share.
