your lowers were prolly replaced sometime, from the factory they are non- greaseable. at least mine were not.
I got my control arms today from oreillys and when i opened the boxes i was a bit unhappy and confused. The driver side control arm was different and much bigger than the passenger side control arm. i inspected the arms on my truck and they were the same size as the new passenger side control arm. Is the driver side supposed to be bigger?
No mine were same size on my 98. Shocks and bushing will cause a squeak too just a heads up of u hear it coming from the rear. Sent from my iFord f150
control arms should all be the same...ball joints are what make the fronts squeak. mine did bad and i replaced both ball joints(upper and lower) and it eliminated the squeak. the upper should be one piece unless you press in the ball joint itself
