Review on Improved Ford AC3Z-3B396-A Front Axle Hub Link Assembly for Unbeatable Performance by Victor Houser

Worked great. I bought it through an online after sales company and couldn't figure out why it wasn't working properly. It stays locked only as long as the pulsed vacuum maintains the vacuum, and then unlocks once the pulse stops. I had an extra factory, a little worn out. I used it to see if that was the problem and indeed it worked as intended. This is why using OEM is so important. And this one on Revain did it. And this for a fair price!
