Stock Upper Control Arm stiff?

I have a 4x4 Tacoma 2.7l. I was changing my upper ball joints yesterday when I noticed that the upper control arm is extremely stiff. I had to use my hammer to make it move off of the ball joint stud. I recently swapped the bushings for polyurethane and used grease. I torques them the proper 87 ft. lbs when I did it. Is it supposed to be really stiff? I noticed on both the upper and lower control arms, there is a small cut out that reveals the inner sleeve. That seems like it would be a great place to add a grease zerk. I am tempted. I am very happy with the bushings. They don't squeak at all.

After changing my upper ball joint i STILL have yet to diagnose the horrid clunky sound in the front when I steer or drive over a hump.

 

Did you ever install zerk fittings in your A arms? I'm getting ready to replace my bushings this weekend with Energy Suspension Polyurethane bushings and was thinking of doing this to keep them lubed.

 

its just fine that way

 

Doubt it. Mine move with only hand pressure.
