Drop both lower inboard control arm bolts and go that way or drop lower BJ from spindle? Maybe the upper BJ would be better. I dunno, but I can see a few different ways that it could be done.

Do I need a spring compressor...I really can't see any use for it.

I've done many f-bodys but have not done a b-body. I'm going with ST 2" drop springs. Cory

Personally, I think it's easier to break the LBJ connection instead of unbolting the arms.

You might need a spring compressor to safely remove the old springs. Regardless, be sure you use a chain from the spring to the frame when removing the old spring just in case the spring gets away from you.

You probably will not need one for the install on the new springs.

Well if you have done the 2 bolts at the a-arm a few times, it is very fast. The first time can be a pain getting it lined up, but it is not hard. I HATE ball joints. I have broke one, and also always break the boots getting them loose. So I like the a-arm bolts. But I have a lift with a good tranny jack that works wonders for a-arm alignment.
For a garage mechanic, I would do the ball joint, it is easier in a sense, and you dont have to lay under the car with a compressed coil above you. [img]graemlins/4.gif[/img]

I think this question is as old as
"Paper or Plastic"

I personally prefer lowering the inside.
A cheap comealong from the control arm diagonally over to the frame at the firewall can help immensely when lining things up.

If you are lowering the car you are going to have to loosen the inners anyway so they can be retightened at the new ride height.

I do it this way at work all the time. Half the time you don't even have to remove the wheels.
Just my opinion, either way works.

I've done it both ways. I prefer the pivot bolt method because each time I try lower ball joint method I have a PITA of a time trying to get the damn control arm past the brake shield while simultaneously trying to get the ball joint stud out of its hole.

The control arm method is about a thousand times easier/quicker in regards to removal/disassembly. It can be a real PITA getting it back together w/o two jacks, however.

I put GW's on my ss. I used the method I read about on this site.I put the car on stands and used a floor jack under arms,removed two inward bolts,slowly lowered arms until springs fell out.You don't need a spring compressor.I put new springs in,used floor jack to compress new springs and put the bolts back in arms.When I put the bolts back in arms I reversed them,I put the nut to the front and the bolt in from the rear.This will make it even easier the next time as the bolts hit the inner tie-rod ends on removal.This was one of the easier jobs I done on this car.

This seems like the way to go. Thanks for the input everyone!

I took out lowering springs and put in 9c1's big mistake but i just bought some ss springs and going to put them in tommorrow. I used a coil spring compressor put my car up on jacks on all four sides and had a buddy help. first unbolted swaybar , took out shock, unbolted lower ball joint and let it all un fold with a jack under the lower control arm. If 9c1's not in the pic you could do with out the spring compressor i believe ill find out tommarrow but have to rent one to take the 9c1's out. I'll let you all know how it go's when i get the ss in.

In our application, the KYBs are junk.

I prefer to split the LCA and the LBJ. Just wedge a pickle fork between the two and give it a good blow. As far as spring compressors I personally would say its a must. Once one of those springs get airborne you can loose a limb if it flys out and hits you. NOT COOL. Usually you do not need the spring compressor when you are doing the installation of drop coils because they are not compressed as much.

When you seperate the LCA and the LBJ I usually have a floor jack under the LCA to keep the spring in the pocket. This also works in re installation, just jack the LCA with the new spring back into the spindle, bolt it together and your done. -Good luck
