Review on ARB 170112 Kit: Enhanced Differential Axle Breather for Optimal Performance in 4WD Vehicle's Drivetrain Assemblies, Differentials, Transmission, and Transfer Case by Maurice Stavros

Bought two for my FJ40. One for my front axle and one for my rear axle. Install axle breather but both kits were missing two plugs. Contacted the seller twice and got no response. The tube is very rigid and uncomfortable to maneuver. It was easier to install two separate filters than to drag the hose like a snake in the middle of the car. Also, the plastic cover that holds the filter in place simply snaps into place and can be easily removed if you're going for a rough 4 wheel ride. A bit of epoxy solved that problem though. Overall not a bad product but the customer reviews, missing parts and stiff hoses lead me to give it only one star.
