Three days before a 3 day overland trip and I have a worrying front end creak/pop on drivers side. Fearing the CV issues, but for now, noticed the lower control arm (LCA) is moving when turning the wheel. This might be source of the metal rubbing sound.
Few questions:
1) Is any moment acceptable between the lower control arm and frame? In the pic you can see the difference between full tilt left versus right of the steering. I tightened the cam nut a bit, but I don’t have a torque wench for 207 ft lb… I did not want to break the bolt. The Toyota service manual -> Front Lower Suspension Arm > Installation, step 13 states tighten bolt and nut if lower sub-assembly to 207 ft lb. After tightening, I have less movement but the same creaking.
2) Has anyone had their LCA bushings fail?
3) Any other quick tips on ruling out CV issue. I did jack up the front and turn the wheel while in Park. No noticeable grinding.
4) Also, is it normal of the upper CV (joint to differential) to move in and out. (C in pic) I could have sworn I saw this move while my son was turning the wheel back and forth. But not 100% sure.

I am not 100% sure if the sound is coming from the CV or the Lower Control Arm. Occasionally it sounds like it is ehco’ing off the skid plates (budbuilt) and coming from below the cab. I get the sound when turning the wheel and sometimes on suspension compression. (eg. taping the brakes) I don’t hear anything at speed, but most likely the road noise is just drowning it out. I have not yet noticed a rhythm to the noise (ie wheel/axle/cv spinning) But maybe my brain is blocking out the CV possibility.
2014 LC200 with ToughDog suspension. About 2.5in of lift. Very light built with only sliders and ALU skid plats. No Diff drop. About 6000 miles on the suspension. Only 46K on the truck. I still have stock Upper Control Arms. Still drives straight with what I think is acceptable tire wear. I will most likely have an aftermarket Upper Control Arm put on asap, but it's unlikely I can find anyone to do that or CV replace work in the next three days, so I feel that If I can rule out CV issues, I will continue with the trip. Plus buy a bigger torque wrench and tighten more, provided it's not the supposed to move and the bushings are not shot. Which is main question above.
Thanks,
