Mine did not come that way, see if you can just pull the seal off you should be able to. Maybe this is their new way of shipping the seal with no damage.HELP! I just received all the parts to replace my two piece driveshaft with the aluminum one piece. The pinion yoke kit (#19257639) arrived with the seal already pressed onto the yoke. After reading about everybody's installs and watching the video, I thought I was supposed to tap the seal into the differential first, then install the yoke. With it already pressed onto the yoke, do I just put it up there, thread the nut on, and drive it home (I mean carefully line up the marks on the old nut and put it back to where it was with the old yoke)?? Thanks.
