Sticky throttle

I notice the gas pedal on my 87 US spec 3.2 cab is a bit sticky at the initial point of push. Everything at the engine end seems free and easy, so I'm assuming its at the pedal end. I notice in diagrams a couple of small roller bearings in the pedal pivot point on the floor. Is this a common wear item? Can they be taken apart and cleaned and relubed? Since they are only two bucks apiece ( a two dollar part on a Ferrari! The myth is true!) I figure I'll order a pair anyway, just curious about others experience with this part. TIA

 

Shades of the power window mechanisms! Thanks!
