Jeep Liberty Window Regulator
There are 2 types of regulators for the Jeep Liberty make sure this is the one you need I ordered the wrong one first.... The regulator from A1 was the correct one and matched the picture in the item listing. Shipping was fast and the install wasnt too bad. This one was a little more expensive than some of the others listed but appears to be a quality product.

part fits
the part was easy to install all bolt hole and connections. the widow goes up and down however there is a slight clicking sound when the window nears the bottom of its' travel. It could be a result of the trashing the package took during delivery. the box was smashed so badly that all the inflated packing packets were punctured and deflated plus the box had been re-taped. Packaging needs to be better.
