Review on Alloy USA 11800 Suspension Ball Joint Kit for 07-18 Wrangler and Grand Cherokee - 4 Piece by Mark Jefferson

These ball joints are great! My 2010 JK runs amazingly well after installing these ball joints. You can lightly lubricate the upper ball joints. I bought a needle adapter (from a local auto parts store), put the adapter on a grease gun and lubricated the lower ball joints. In hindsight, I should have lubricated the lower ball joints during installation as that would be more difficult after I put everything back on the jeep. A tip: lubricate the upper and lower ball joints when installing.
