The squeaking is likely your sway bar bushings.
Now there are factory OEM grease points on some things:
Control arm ends, pitman arm, tie rod ends, slip spines on the drive line/T-case. Just not on the U-joints, ball joints, and maybe a few others. The reason they do this is the factory installs SEALED bearings so that every time you drive through water and such you don't have to grease the bearings. A Greaseable bearing is not a SEALED bearing thus you have to grease them to get the water and debris out and Flush the bearings. In sealed bearings you don't have to Flush bearings. Sure they can ware out, but usually on average they out last flushable bearings because customers don't flush (grease) them like they should. If they did they would outlast hands down I would think.
