re: Broken Engine Mount and Sway Bar Bushings

Depends.

A broken motor mount - depending on location and how many others there are can be serious - torque from the engine revving can allow the motor to twist. If it twists enough shite can break bad.

Worn out sway bar bushings, again depending on how badly work, can allow a "death wobble" type situation or most likely your vehicle will handle like a wet rag - a lot of body roll in the turns and feed back in the steering wheel when on bumpy roads.

Of the two the motor mount would be my bigger worry - again depending on the location.

The good news is if you're at all handy you can fix both of these yourself with a little help from You Tube.
