2004 Toyota 4Runner SR5 - Frame rust: currently not drivable due to complete breakage from the rust. Driving 2 hours home on the highway I almost lost control, pressing/releasing the brake and/or gas pulls the steering side to side and sways the truck (fish tail) due to damage from the frame rust/breaking. There is no control of the rear end. Truck was in great condition prior to the frame snapping.

Firestone wonât perform any service if the vehicle needs to go in the air (tires, oil..etc)…
