I actually had 5 control arms to test using a bolt:
1 987 rear arm, Trw
2 986 rear trailing arms, trw
2 986 front arm, brand unknown (from Elephant, they said Asian but brand unknown)

The force to move the bushing using a bolt was the same for all 4 with the exception of the 987 trw which was easier, I could actually move it by hand (I could not with the other one i installed already)

After moving them about for a few seconds the resistance was about the same. Edit: After taking one apart, I believe the resistance I felt was the resistance of the stiff rubber boots and not from the inside parts...

The 2 old 986 arms moved very easily. I am.going to take one apart to see what is inside.

The reason I am replacing mine is the guy that installed my front GT3 LCA said they were shot. So short of the ball rattling inside, I am not sure how to tell when one is shot.

Maybe I will know more when I take it apart...
