Review on ACDelco 45H1157 Professional Rear Spring by Matt Davis

These springs were easier to install than I expected. There is a bolt on the lower rear arm that you remove, an 18mm bolt head, an 18mm nut and the arm comes off. Pull out the spring, replace the rubber buffer, put in a new spring, jack up the lower link, screw in, tighten, put on the wheels, done. I have a lift and all the necessary tools and I did a couple of these in 30 minutes. If you make them on stands and a jack, I think you can still make them in under an hour. Broken spring repaired. There is a gray color marker showing where up is. Light. It's important to have 18mm tools as most kits skip them. They are sold in farm shops and auto parts stores. Don't be afraid of this job.
