On the cup the top mount sits in :y

I am totally lost. So top mount is made of rubber, next part is bearing and next perhaps this lower mount. It seems to be corroded and dirty. I cannot find yet any holes. Have to disassemble the spring first - during coming week-end. Could someone describe what is the right way to put it back. Guess it is not symmetric part?? Strut is already on the floor.

Apologies. I originally mentioned the "lower mounting dish" for the spring. I actually meant the upper dish/spring seat. It's item 2 in this drawing. There are pictures in this thread.

In the photo of the "top hat" upper spring seat, there are two similar holes. Mark the hole that's inboard when the assembled strut is mounted on the car. And make sure that your reassembled/rebuilt  strut has the hole in the same position.

OK, thanks. So Upper spring seat is part No. 2. As that part turns together with the front wheel and strut (when steering wheel turned) it is still today in a right position as I did not remove the spring yet. Do you all agree?

So, what happens if this spring seat is in wrong position? What is "steering knuckle" you are talking about.

The bottom of the strut has a collar on the shock absorber with two bolts which attach to the steering knuckle. You can use this as a fixed reference point. The upper spring seat needs to be reinstated with the same inboard/outboard orientation on the assembled strut that it started with. One of the two holes is an alignment hole. So mark the hole relative to the centre of the knuckle with a paint pen or similar.

If the upper spring seat is not correct then it won't be properly parallel to the bottom seat. The strut can be assembled with the upper mount 180 deg wrong. Some report that the strut assembly then fouls the mounting turret in the car body upon turning. I suppose the spring might also be distorted, can't remember about that.

OK, start to understand. I do my best. Bottom bolts and Camber Setting is clear.

I found them now and marked, thanks, good point. I did not know this.
