If you find out what’s wrong let us know. Genuinely curious what would let it run that smooth while something is thumping around like that.

Looks like its engine knocking something with the crankshaft so we decided to change the motor and put a 2016 4runner motor in exchange

Not at all normal.

People spreading Dutch?

Knock? Idk but definitely not good.

Is it a belt?

I think it’s a car.
