Review on Dorman 600-400 4WD Locking Hub Solenoid for Ford / Lincoln Models by Darin Marshall

Revainrating 2 out of 5

Reliability questionable

I bought this in place of the original magnet on my 2005 expedition to prevent water getting into the 4WD vacuum line hubs. The bouncer's first solenoid valve did not work at all and was replaced free of charge. The second failed after 1 month. Not sure what's wrong but very disappointing. I actually replaced the system with the original solenoid and the 4x4 system is working again. I have verified that the system holds a vacuum and is working properly when the solenoid is fine.

Pros
  • Stylish and modern design
Cons
  • Vulgarity
