I installed poly bushings on my Saturn a few years ago. It was the single most painful experience I've ever gone through while working on a car. It took all day Saturday, and all day Sunday. On Monday, I had to order new bolts from the dealership. On Wednesday, the bolts came in and I got the car aligned. So for 5 days, my car was out of commission. I broke a ton of tools, got melted rubber all over my garage and driveway, it took a week or so before my hands were finally clean again, and after a year or so the front lower control arm/sway bar bushing came apart while at an autox and I had uncontrollable toe-out on one wheel.
Hopefully the install goes smoother and the bushings last longer than mine did.
