    I had this head scratching problem too but when the car is on the its wheel the geometry changes and the parts clear each other. It is very close though.

    If you would remove them from the knuckles, you would see, that there's a woodruff key inside (#7). They are mirrored parts. You cannot swap sides. Except someone omits the woodruff key.
    Prices are also based on availability.

    Thanks for that information... I am trying to think of anything that could be assembled
    wrong that could cause our problem.

    start with going through any pics u may have taken prior to disassembly, and look through the parts manual. check the A arm bushing spacers, ball joints etc. Btw how did you tighten the control arms back on the car? with car on floor or measurements?

    I was thinking the same thing after I posted. I was just going to suggest you check that. Glad that's the case. Should be an easy fix.

    You are right Martin. I was just looking through the pictures and concluded the same thing. Perspective. At first I though it might be different parts for different years but checking I found all years used the same lower wishbone. Optics is a *****.

    Should not touch at full droop. Full droop does happen when driving and you cant have a steering issue just because the travel is at the limit.

    Pulled out the wrenches and tape measure first thing this morning - already fixed! :)

    I've noticed that some people seem to get offended when I point out something that is wrong with their car... I never mean it as an insult, just something that they might not have been aware of. So thanks again for letting me know something was amiss with mine. :)

    Hello together,

    This thread is fascinating me so much, that after I came home from an extensive travelling through France I took my camera again and shot a few pictures of a few different positions :), from which one brought me a surprise.
    Sorry, but I was not in the mood for taking off the wheel.

    First of all, as an addition to a previous post from me above; To avoid further discussions about the lower wishbone angling up or down.... there's no angle at all. This right angle shot shows, that the wisbones are straight and there's no angle.
    It also shows the parts with the wheel just in the air and in straight forward position. Still a lot of space. Picture seems to show the wheel still on the ground. Actually it's a few mms off the ground. I could turn it by hand.

    Here are some pictures with the wheel in the air and steering at it's end position. And here's my surprise:
    The steering arm comes close and actually touches the link, but not on the track rod end nut, but the arm itself. See red circle on second picture, which shows traces where the arm touches the link ( have turned the wheel a bit back to show the contact point):

    I think I can live with that, since I just noticed it because of this thread after 22 years of ownership. And it's not a steering/suspension condition, which often occurs while driving :)

    I will not be back at the shop until Monday, so I will measure the floor height then,
    We documented everything with pictures and it looks like the tie rods were hitting
    before we took the car apart. I bought it not running in an estate sale and the car
    has been serviced by non Ferrari mechanics for years, so anything could be wrong.

    Now I am really confused... In your first picture the wheel end of you lower
    wiishbone appears to be straight.. Mine curves up and some other ones
    pictured in this thread curve down. Mine is a 1981 GSTI. I wonder if there
    were several types?

    Sorry, don't want to cause any confusion, I mentioned it already in a post above and JohnK confirmed. It's a picture angle/perspective issue. I'm sure, when you look at the wishbone at right angle you will confirm too.

    Need to read all the post, Bob. All 308s and 328 use the same lower wishbone. They are all straight. The difference seen in the pictures is optical due to camera angle.

    It must have been an optical illusion, here is a pictures of the wish bones off
    the car and the bottom front ones are straight.

    my opinion is ONE part at a time. we all had a lot of opinions here which can be confusing, but I think you need to check all the bushing spacers, ball joint orientation, correct steering rack length , and I would want to be sure that the A arms are bolted in the correct location to be sure that they are not pointing downward ,upward etc. on my car which is a GT4 IIRC the chassis height is 5.25 from memory. We have seen that droop can cause a interference or partial interference condition, and constant interference in your case. So I would say start taking apart and examine everything. I also posted about the upper and lower A arms not lining up, but that could also be a photo illusion. Mike

    and I still haven't seen the inboard edge of the ball joints. something bugs me with that, I feel from memory that they pivot more one way than the other , though they could be different on your car than mine. But most of these old F car V8s have used the same parts since 1973

    Were you thinking that by upper and lower A arms not lining up it
    would create a negative caster angle lowering the steering spindle
    lever so it would hit?

    I am pretty sure the ball joints are right. They came from Bill at GT Car parts.
    I also compared them to the ones we took out and they measure the same.

    I saw on other threads on this site that some people replace the
    factory dog bones with heim joints. If all else fails I could do that,
    but if something is not right in the front suspension I would like to
    get it back to factory spec. To me it looks like the controlling thing
    is the bolt that goes through the shock and the dog bone in the
    lower a arm is the main controlling item. If the dog bone is vertical
    it's top is fixed in dimension to to lower a arm. The steering spindle
    lever is fixed to the spindle and i't height is fixed to the lower a arm
    through the lower ball joint. The only thing that I see would raise and
    lower it in relation to the dog bone would be the caster angle.
    Does that make sense?
