I installed Mevotech upper and lower ball joints on my 01 foot trip 2 months ago. I went to an alignment today and 3 out of 4 are so bad the shop didn't level the truck. Absolute waste of time and money. Likewise. Installation Failed - The green threadlocker on the nut grips so quickly that the hex head you use to prevent the ball joint from rotating during installation pops out. I will add after the upgrade.
