Yeh, it took some mad force to get them in, I tried to pull them out to put some lube on but, heh, they didn't go anywhere.

You will probably need a dremel, some plyers and the help of Arnold Schwarzenegger to get those hinge pins out now! Did you at least straighten them first? If they are bent, they may bind your suspension arms and inhibit moevment.

Arms move fine, I did straighten them but it wasn't possible to get them perfect, lets hope I don't need to take them off ever again! :D

Also, is it possible to put CVDs in without taking off the arms from the bulkheads? :(

Sure, but you will have to remove the pillow balls/knuckles.

Actually it should just work if you can remove only one hinge-pin.

Thats good then. :)

Only the stock ones are hard to get out. So I should be alright getting the ones supplies with it out, with those e-clips.
