[Update] I have been traveling lately. My brother replaced the rear driver toe link. The old one was frozen and could not be adjusted. He eyeballed the adjustment based on the old toe link.

After the replacement, no more swaying for now.

I still have to change the compressor and have the truck aligned.

Thanks to all for the input! Also, thanks to Dakota Traveler who mentioned a possible toe link.

BTW, so far so good on the aftermarket strut used by Waffle Square in YT that was installed in the front right.

 

Good to hear. And I like it when I am right for a change. LOLOLOL

Onto the next challenges for you!
