Review on 🔧 Dorman 600-102 4WD Actuator: Perfect Fit for Chevrolet, GMC, and Pontiac Models by Rob Marsh

Made in China. It's not a problem, but the design isn't the best. There are a decent amount of sharp parts, any of which can damage the thin rubber vacuum flask. So far it fits the 2000 GMC JIMMY it was bought for but I don't think it will last long. A common cause of failure of these parts is the vacuum switch that controls this actuator. They should be replaced by pairs from my experience. If that drive fails, I'll update this post.
