If your shocks haven’t been rebuilt/swapped by this time you’re getting close. My 2020 shocks started “buzzing” @ startup & initial drive as each shock went bad & the solenoids would go nuts on startup not getting the right feedback due to weak pressure in the shock low nitrogen or whatever. If (when) they start to do that that’s when you REALLY know you’ll need to do something. The shocks are so cushy new & they degrade so progressively it really is hard to tell from the drivers seat they’re worn (unless you hop into a fresh truck back to back)
My guess is swaybar endlinks as others mentioned- fwiw I rebuilt my suspension in 2 stages- first I replaced all 4 shocks w/ shocks by hammer rebuilds + Deaver +3HD springs & added SVC adjustable collars to the front around 81k miles
The improvement was immediate noticeable, then @ about 86k miles after saving a lil more $$$ & buying some more parts since I started having IWE issues & when putting truck on lift I found the driver front wheel bearing had a lil play & both CVs were pretty worn since I had already put the $$$ into the shocks/springs i was like F it lets do the rest: 2 new moog wheel bearings, 2 trakkmotive AAR axles, & a full front end XRF suspension package (see attached pic)
XRF kits are common in the super duty/diesel truck world & are also “Baja tested” but have a rep for being extremely robust & durable come w/ “million mile” warranty - this XRF line is supposed to be more durable than their “lifetime” brand & I like that they’re NOT grease able in this case (claiming million mile durability w/o needing a grease fitting)
Upper a-arms complete, inner/outer tie rods/swaybar links & ball joints for the lower a-arms (pressed in just fine) - it’s kinda price but kinda not since they’re so robust & most of the labor is “redundant” installing all of this stuff @ the same time.
Just giving some food for thought on a suspension rebuild/tefresh
Lastly- my stock endlinks wore out, the mevotech ones I got from rockauto lasted even less (to my surprise as the mevotech links on my vette are great) but I’m confident these XRF ones will hold up nicely & yes you can buy just endlinks alone from American undercar
