Pulling to the left/wobble @ 40-50mph / New Lower Control Arms, align cams, CV Axle.

[happy camper]

2007 4Runner, Sport Edition, 4WD, 370,000miles.

Recently had two new Toyota OEM lower control arms, new alignment cams/bolts. New CV axle assembly Toyota OEM, part number 37140-60380, which is the newer axle, and shows to be compatible with the 4th gens.
Almost new Michelin LTX Defender 2 tires. I have had the tires in front swapped sides and balanced again, after installation. I have had a new OEM Toyota main drive/propeller shaft installed in the last two weeks, and wobble/pull was happening before this.

I am trying to figure out what could be causing a pull to the left and a steering wheel wobble from 40mph-50mph, with the wobble usually occuring only one time, on the first drive of the day.

I had a trusted mechanic install the parts. All Toyota OEM from Olathe Toyota. I am in East Texas. Actually the mechanic works at an old school frame and alignment shop (Hanks Frank and Wheel in Longview, TX), so I do trust their alignment. But I have also read posts where the 4Runners are tricky when aligning..
I am considering just going to the local Toyota dealer and get their alignment job?
Something that may be important: The CV Axle assembly I had installed was 43430-60083, which I have read where these work in the 4th gens, and this was installed on the left side. It's not the original which I think is 37110-6A440 Just a moment....

Could the pull to the left be because of the CV axle not being the original part number? The axle assembly I had installed is the newer version with the nut where you indent it into the notch on the shaft.

Ideas? Recommendations? Thank you all in advance.

Especially with that kind of mileage it could be in the back, the rear axle being off and trying to push it sideways. Try the string test, with the wheels pointed straight ahead, steering wheel straight, flat ground, wrap a string around all 4 tires. I don't know offhand what F/R track is, but everything should be the same, either straight or the same gap per axle.

Of course you've still got wheel bearings too, especially for the wobble.

I do appreciate your reply. Please know that there was zero steering wheel wobble or pull to the left before installing new Lower Control Arms, and new Toyota CV Axle assembly.
Also, I installed new, OEM Toyota front bearing assemblies less than a year ago. And about two years ago, installed the rear Dorman bearing/axle assemblies.
The shop checked a couple of days ago to make sure that everything was in place, no disconnected pieces.

I'm going to get tires balanced again and rotate front to back to 100 percent rule out a tire. But as I said, wobble and pull began after the LCAs, CV Axle install.

Put it up on 4 jackstands, really sturdy ones obviously, run it at some speed, like where you would be getting the wobble, and look/watch/video things to see if you see any odd movement? Might have to do it in 4WD to get the fronts turning. While not standing in front of it just in case. Maybe sit in the drivers seat and have someone else do the observation/camera work just so you can stop ASAP just in case. It won't load the suspension, but it might give you some indication of what's happening.

I'd still do a string test, cheap and easy enough.
