That's what I'm finding out. I had to brush up on my searching skills. I have seen just the pin pop up from time to time, but it was years ago. I'm really dreading having to buy the whole knuckle just for that pin.
I found out that it's not available separately, so I had to order a knuckle. I ordered two in fact, just in case the other one wound up the same way. I replaced the passenger side knuckle and was able to get the strut installed. It was a PITA also, everything is rusty on an 18-year-old car.The part that the strut sits on is screwed into the knuckle assembly. It can be removed with a 32mm socket IIRC. I'm trying to find a picture of it, but can't find one. I don't think that it available separate. Do you have a picture on how bad it is?
