Coil spring alignment '64

I'm installing the coils as part of a complete suspension refresh and front disc brake conversion and while the top of the coil seems to be in place, the bottom is not at the end of it's seat. Is this going to be an issue? I'm also not sure if I'll have the clearance to get the spring compressor out but that's another matter, ha! The springs are stock moog 658a. Thanks!

Bottom of the spring has to sit in the spring pocket of the lower control arm:

I got it to align by lowering and adjusting but like I said removing the spring compressor is another matter. Oi vey. It's like a catch 22. If I put the compressor in coils closer to the middle of the spring they don't compress enough - too far towards the ends and I can't remove the tool once unloaded. Back to the drawing board.

Also for when I do get it redone I noticed this gap between the spindle and upper ball joint. Is that going to settle and I just keep cranking down the castle nut to adjust it once everything is put back together? Lower ball joint has no such gap.

There should be no gap. Either that spindle has the wrong size tapered hole (which is reamed at seven degrees), or your ball joint is off a pick-up truck as it has a super sized stud coming out of the ball joint (you, pick).

I'm guessing you have a brand new aftermarket dropped spindle. If so I would be showing the guy that sold you that part your gapping photograph and ask him what is going on.

Speedway sells reams to open car spindles up to accept pick-up truck ball joints (which are bigger and stronger for racing). But before I got creative I would find out what is supposed to be there.

I do have new spindles but definitely the right parts for both as I bought application specific sssb spindles and 58-64 b body ball joints from ecklers in a front end kit as I recall (been a while). Are you sure they won't settle? I can get the cotter pin in no problem so the castle nuts seem right and the bottom ball joints a good fit to the spindle. Got both springs in and I'm still alive - hate dealing with coils. Thanks for the help!

Sure you put those ball joints on right? The bolts holding the ball joint in place should not be holding the tension of the spring. They should just be keeping it in place.

This is what mine looked like:

May have just been a little over cautious as if think I've got it sorted. It doesn't look like a gap so much as the ball joint boot is hiked up from sitting down on the frame. It should sort when I put the upper bump stop in. Got both springs and rotors on... Seems to have come together nicely. Used the same compression tool you recommended in another thread - borrowed from autozone.

I hate to say it, but I am pretty sure you put your upper ball joints on the wrong side of the control arm. Be absolutely sure you got that right, as if you are wrong, you could be going down the road and have the ball joint separate from the control arm, allowing the spindle to flap all over the place, probably with bad results if going very fast.

Look at the picture I posted above, the ball joint sits on top of the control arm. No way it will pull through the hole, the three bolts just keep it from moving around and should the bolts fail, the ball joint just wiggles around in the hole in the control arm. On your picture, the three bolts are supporting the spring and suspension stresses and if the bolts failed, the ball joint would completely separate from the upper control arm!

I went back and looked at the pre upgrade pics and definitely put them on the way they came out (had to get the rivets out and droll the bolt holes bigger. Here's a pic from the back looking forward... Click image for larger version

Oh I see what you mean now... The ball joint points down but goes through the hole for support. Doh! We'll maybe I can fix that with a jack and not have to remove the spring. Always something.

Glad you could get that sorted without taking the springs back out
