Shaking

I have a 2009 tacoma and have 124000 miles on it. Yes, I know it's a lot! I have a 2 1/4 in level kit on it with oversized tires. I recently started noticing a slight shaking when I'm idling at 45mph and it's driving me nuts. It now has a faint shaking when I go to brake. I had my rotors spun back in November so I'm not sure it's that. Just wondering what you all may think. Does it sound like a tire/ truck alignment problem? I've never had any issues with my truck. I am up to date with all my minor and major services too. I hope it's nothing major:/
I never got a fuel service done, do you recommend that?

Thanks

 

U-joint? Bulge in a tire?
