Default Changing front springs, what else?

I am going to be replacing the front springs and shocks on my 68 roadster. While I'm at it what else should I be replacing (bushings, etc...)?

A question I would ask is how old are the original A-Arm busings, ball joints and tie rod ends. How many miles do those components have.

You can look at those A-Arm bushings to see how cracked they are.

If I were replacing the front springs and had the arms apart, I would certainly replace the bushings in them. Go the extra mile now and save yourself the trouble in the future.

Just my .02.

The tie rod ends aren't that important right now, unless they're obviously worn out. Definitely replace the control arm bushings, ball joints and the rubber stop bumpers. I'd recommend polyurethane boots for the ball joints and tie rod ends. All of that stuff requires the entire front end to be disassembled to replace, so there is no real reason not to do it while the system is apart.

We're you planning on taking out the arms? If not, replacing the shocks and springs is an afternoon job with the right tools. To go after the upper control arms is more involved and (at least on my 79) requires a lot of wrenching in the engine compartment to remove. Perfectly doable, but much more involved.

Low hanging fruit while you're at it: new end links and bushings for the sway bar, new upper and lower ball joints, new flex hoses for the front calipers?

Thanks for the info. I really have no idea how old any of these components are. I purchased the car about 3 years ago without any service documentation. I figured that while I had it apart I might as well take care of what ever else I could.

The main reason I am changing the springs is that one side of the front end sits higher than the other. I have been told that one spring is probably is SB and one is a BB.

Unless the springs are tagged I'd be interested to hear how this was identified. You may not need to change your coil springs. You should get a second opinion. How much heighth difference is there?

Sorry, reread your post and it's "probably".

The passenger side sits about 1-1/4" higher then the driver side. Any other suggestions about possiblitlies would be appreciated.

That's a good sized gap. I'd stay the course and pull the springs and possibly replace the bushings.

You can get the "wire diameter" off your front coils to see if they are different...then go from there...

Since you don't know the history of the car, I would think about having the frame checked before tearing everything apart. It could have been in a accident and not straighten correctly or at all...JM2C

I don't have any issues with 'crabing' or anything like that. The car tracks perfectly straight. At 80 MPH I can take my hands off the wheel and it run straight. Do you think it coudl still be a frame issue?

Doesn't sound like it. But with the height differences you described someone had to make some suspension adjusts to make the drive straight and true. Was this because of the wrong spring(s) or an out of align chassis, I don't?

But IMHO, before I would go out buying parts and ripping my car apart I would want to know the frame is good.

I think someone else suggested measuring the diameter of the two springs to see if you can determined if in fact they are different, that's a good idea too.

Not so much a frame issue, as one of the springs is not seated correctly in the top pocket, it's cocked off to one side, and that 1.5 inches rise is what you get when that happens....course if the alignment is in fact done spot on in that condition, you will have to realign the front after it's corrected.....figgers..;-(.....

you may want to check the steel leaf spring in rear for any broken leaves also....
