Lower Control Arm ball joint bolt seized
Trying to replace the lower control arms on a 2011 Yaris.
The bolt that attaches the control arm to the bearing assembly (locked with a cotter pin (which was removed)) spins without loosening. I placed a jack under the ball joint and added pressure but it wasn't enough. Can I use a pair of vice grips through the ball joint boot and clamp down long enough to break the threads loose Note, I am using thread oil to possible loosen up the threads I am replacing the lower control arms because the rubber around the rear bolt is cracking and possibly failing. |

They can be tough, the ball joint stud is usually held tight in the knuckle while you unthread the nut. I'd soak it for a while, if you have a torch then you can heat the nut up.

Now the forward bolt hits the engine block and can't be removed. Oh, Toyota, you so crazy. |

just had to cut mine off with a torch. The bolts for the lower control arms are terrible and I ended up putting new arms on with bolts for a mercedes clk230 (perfect fit/length and same thread). Its a very common issue with these bolts being a bad design from toyota so replace them asap especially with higher mileage
