Installed core 4x4 2in rear sway bar end links.
Also replaced my messed up drivers side from sway bar end link. Ive had the clunk for a while and was trying to ignore it. Didnt last. While i was under there though i did find out the newer end link i got uses a 19mm nut on the bottom instead of an 18.

hopefully this helps the clunk.
I also noticed that the retention bolt on my rotor was hand loose..enough the rotor moved while putting the wheel back on. Wonder if maybe that was also part of my clunk…though i suspect not since i assume it all sits tight when the wheel is on.

Last week i recentered my my rear axle, very easy and definitely helped the truck drive normal again…the added height of the tow springs had it shifted to the passenger side with the stock track bar
Heres what I used. No greasing required and it will work for road duty and trailer pulling.
