The shop manual shows there should be 2.9-3.0" min space between a horizontal straight edge reference point on the frame(?) and the PPF by the tail of the trans. The reference point for putting the straight edge in the manual isn't very clear. Can anyone help me with what this point on the fame is? A picture would be great. I've searched the site but nothing seems to come up. If I missed it please point me to the link.
so reference point isn't the frame, like a miata, its the brace that goes in the tunnel right there. i don't recall but it should have a flat bit on the bottom.
it does set the U joint angles so if its off things can be weird
I've never found that there is any substantial adjustment you can do with a PPF. If it doesn't line up, the PPF is bent and you need to replace it.
Had a friend that I helped put back together a previously single turbo car. The PPF looked fine but on the car it shoved the transmission to the right side of the car so the shifter housing was touching the trans tunnel. There were no cracks or obvious damage on the PPF, I tried comparing it with a good one and you couldn't visually tell that it was bad. We also tried to play around with adjusting it and every time it went back identical in the same place - tighten one side first, the other, you name the trick we tried it.
Always tighten in the order of the FSM with diff first and top to bottom. If it's way out you can slacken the box end and jack the box to raise it and adjust the PPF a little but normally they kind of sit where they need to go.
