Mine are a pain to get to. IIRC, they have to be installed in just the right location which seems like it's toward the rear but turned like 45 degrees toward the middle of the vehicle (that's intended to be a guess, not an exact number). I still have to turn the front wheels to move the grease joint enough to expose it. Then it's still a pain to keep the grease gun attached as there is very little clearance.
Turn your steering wheel and see if they come into view.
