I agree you dont need one but if you are lifted at all that sway bar helps emensley especially on highway and crosswinds. I installed a rear sway bar for that reason. Night and day. Easy to disconnect if off roading.
Are you talking about selling the one you have with 23k on it? If thats the case no chance you will get that money. Not even close.You can get that spec'd vehicle off the lot now brand new at that cost. Boat sailed on that.
Placebo effect? Lol…Yeah Idk thats strange. My axle was off by 1.75 inches and there was no difference in body roll either way after I replaced with adjustable track bar. Just made my ocd feel at ease seeing the tire poke even on both sides.
Does it go away after warming engine? sounds very similar to mine but is gone after up to temp. Been like that since new and I have heard same noise in these 2.3 ecoboost in other broncos but is gone after warming up.
