Pressing very hard with 1 hand to compress ,

Stock or aftermarket, have they done many miles, any signs of oil??

I can't remember exactly how hard it was to compress the rears ones on my 182 when I last did them.

Seems like stock, at least the dust covers say so. Don't know their history, got the car half a year ago.

Still wondering if I should change the shocks, the ride isn't smooth and the car is stock. Also on some slightly bumpy turns, the grip is on\off throughout the turn, not consistent, seems like the weight is shifting side to side repeatedly. I didn't have the chance to compare to another ph2.
Does the video tell anything ?
Any way to tell if the shocks need replacing, or at least know if I need to change all 4 or only 2 ?
