The upper and lower ball joints worked great. The upper does not press in far enough to install the snap ring but neither did the OEM Ford upper ball joints. Used the lower ball joint grease zerk to fill the upper ball joint and then installed the plug. Installed the zerks on the bottom ball joints. Re used the wheel bearings and inspected the u joints while they were out.The ride seems a lot smoother but it's still a 3/4 ton truck so not like a half ton. Turning is a lot easier and no wandering. Got rid of the popping and the ball joints that I removed were Moog and rusty and worn out terribly. Hoping that I don't have to use the warranty within the next 2 years!!!

High quality
These were very high quality, its similar to comparing vandium steel tools to impact rated tools. Can tell the quality over oem; worked perfect on my 2008 f250.

Good so far
Bought for 2012 F250. Truck has 150k miles w/ 37/13.50/20’s. These parts are very labor intensive to change out. So far I’m satisfied with the quality and the warranty backing this product. Time will tell.

Will not fit rear wheel drive.
I really wanted to use these. Nowhere does it say they only fit 4WD trucks.Since I must have the only RWD F250 ever made, they wouldn't fit, and had to be returned.I was pressed for time, and had to get another brand locally. Big disappointment.
