Vibration at 70MPH

I replaced the rear brake pads about 2-3 months ago but I don’t remember seeing those. Doesn’t mean they aren’t there, just don’t remember them. If they were seized, how would that cause my issue?
They are located on the back of the rear backing plate assemblies on the side closest to the rear bumper. Every stock 3rd gen has them. If they don't move freely and get seized after you apply the parking brake, then when you release the parking brake handle the rear parking brake is still engaged. This can cause rear brakes to drag and could cause a vibration or pull depending on if one or both seized.

Does the noise sound like it's coming from the front or back?

Gotcha. Noise is coming from the front. I feel the vibes in the steering wheel and even in my seat. That’s why I replaced the drive shaft. It came with new non-greasable ujoints.

Since you're 2wd the only rotating assemblies you have up there are wheel bearings, tires, and wheels. I would be willing to bet that they pressed one of the wheel bearings in wrong and that's your problem. You can try rotating tires and seeing if it changes any.

That’s what I’m thinking as well. Really pisses me off because I pointed it out to the tech but he said it was normal. I should have stuck to my guns and made them redo the work.

I’ve rotated rebalanced the tires with no improvement.
 
Side note: the other other day when leaving work, after reversing out of my parking spot and shifting into drive, the car acted like it didn’t want to go forward. It rolled forward slowly and the RPMs revved up but the car had no acceleration. I stoped and shifted through the gears and tried again. There as a slight lag and then off I went without issues. Hasn’t done that again since.

Rear brakes sticking due to gear oil contamination??
 
So.... I had the same issue. Took it to Discount Tire to check the balance. The guy told me that Toyotas have this complaint all the time with the 10 ply tires. They rebalanced (for free even) and it has helped noticeably. There is still a slight vibration but more more tolerable. They use the roadforce balancer at that shop.
Here's a link to help you find a shop that has the proper balancer. https://www.hunter.com/find-equipment/?
