Identical to OEM
Replaced both actuators on my 2004 F150. Water had gotten into the passenger side Via the vac solenoid on firewall and it would not disengage. Took 3 hours and saved a boat load of money.

defective product
I purchased a set of two and had a mechanic install them, one turned out to be defective and would not hold vacuum. had to get a replacement and pay for another install on the drivers side. The customer service was great but it ended up costing me more than if I would have bought them from the dealer.

great replacement
Another great part from 1A auto at a great price. Replaced and got rid of that horrible grinding sound (almost like dragging sheet metal). Replaced in October and 4 wheel drive worked perfectly all winter. Bring on mud season.

Easy Fix
Great product. Was an exact fit to replace oem actuators. Easy install and solved the clicking noise i was hearing which turned out to be a broken left actuator.

Great parts at fair prices
The parts I purchased fit just like the oem parts did. the main part that caused the failure had been upgraded and reworked from the original to prevent the failure a second time. Overall very happy and would recommend them to anyone!

My cv-joint doesnt have the 6 13mm bolts referenced in the video or I cant find them on my 2013 Ford f150 4x4? Im trying to change out the front actuator hubs
Chris S October 18, 2017
They are on the inside of the front knuckles
Gene S October 19, 2017
Changing these doesnt require removing the cv axle. I recommend this method.
Michael S October 19, 2017
Changing these doesn’t require moving the cv axle.
