You should be ok to drive it to a shop for rebalance. I’d probably have them all rebalanced from looking at that one. Also try to check and make sure it didn’t damage anything else.
I was about to reply stick on weights but you found the problem. I’d take the wheel off and try to make sure it hasn’t damaged anything. They will probably have to rebalance the wheels and use knock on weights.
I had the same problem out of a different brand trackbar. Mine would rub the mount and make sounds like crazy. I had them let me return it and went for clayton trackbars. Theirs have a flat spot on the trackbar in that area to clear the mount.
Take pictures and even a video of what is wrong. That way when you talk to them you can email the pictures and video. I had one of mine that the high beam stopped working on. That’s what they asked for and sent me out a new one pretty quick.
I did the same for awhile and it was hardly noticeable. Unless I actually told you there was a difference you wouldn’t notice. No difference in driving or overall ride.
I talked with apex at jeep invasion and they addressed a lot of your concerns with the new tie rod ends. They also use what they call a ninja washer that once you have the steering set where you want you bend the tabs over the nut and bar and it keeps it from backing off. I run the rpm setup...
I have been using the vavoline in the squeeze containers in mine. It has the friction modifier already in it. So you would be good either way if you have a limited slip or not.
