I installed the Ready Lift SST leveling kit on my 2019 Custom Trailboss about 8 months ago and have recently noticed some rattling when going over bumps. After checking the torque on everything and finding that nothing was loose, I did find that there seemed to be some wear in the tie rods and lower ball joints. I decided to replace the sway bar links, tie rod ends, CV shafts, and lower ball joints. I ordered some lower ball joints which I believed would replace the old ones. However, once I removed the lower ball joint on the passenger side, I found that the one's I ordered were not the same and have now discovered that no one is making replacement lower ball joints for the 2019+ trucks, so it looks like I'm going to have to order a whole new lower control arm. I suppose it's easier to just change the lower control arm but replacing just the ball joints is about four times cheaper.
