3" toytec suspension lift with 285's on 2014 4x4 taco vibration issue

I just installed 3" toytec suspension lift and put 285's on 17" rims.

When I go from a complete stop to accelerating, I am getting slight vibration. My mechanic said it is most likely because of the aggressive tires that are on there and not to worry, but....... Does anyone have a clue if it could be something other than that, and if I should be concerned??????

 

Yes, mud terrains vibrate. Mall crawling comes at a cost

 

Completely normal with mud terrains. You feel the knobs at low speeds.

 

Mud terrains give a crappy ride. Especially if you have E load range mud terrains

 

Carrier bearing drop kit installed?

Might want to do a polyurethane carrier bearing as well.

 

Sounds like axle wrap. Do you have lift blocks in the rear? That will make it worse

 

Woah woah guys I think y'all are being dramatic. Don't scare the guy. Without a better description there's no sense in assuming something is terribly wrong

 

Lol. Sounds just like a take off drive line vibration.

 

Zackly what it is
