Default Leaf spring -- replace or recondition?

My original rear leaf spring on the '79 is starting to "fan" a bit and has some surface rust. I had a mechanic tell me that I needed a new one. But most of the people I talk to (who know what they're talking about) are telling me that I can recondition it myself (ie: take a hammer and pound the sheets back into alignment, sand it down a bit, then wrap it with a new fitting and put it back in).

Without seeing a picture of it, what do you guys think?

Does anyone have any pics of doing this themselves or any stories to share?

Should I rust-coat it after I sand it?

Replace it. The metal leaves wear out and lose their 'spring' no matter how much you sand or pound with a hammer. It's still a three decade old spring.

I have a stock leaf spring that I can sell you. Its from my 76 vette. The spring may have been replaced with one from a 79 vette because someone replaced the diff cover with a stock 1979 one.

I just noticed you're all the way in honolulu, so shipping would be a killer from Canada.

Yeah shipping would be plenty. Plus if I'm going to replace it I might as well get a new spring instead of just replacing it with another old one (even if it is in better condition).

Default Rear Spring

My 78 rear steel spring was nosy, I lube it but no change. Took it apart, sanded, painted and installed liners from a Spring Shop(truck repair place). It wooked prefect, but it is 30 years old and now I planning on a plastic replacement.

I believe you can have the rear spring re-arched at a driveline shop. I have no personal experience using a re-arched spring, but I know it is common practice. I would say though that pounding on the spring with a hammer as a do-it-yourself fix is probably a waste of time.

Metal springs have "memory," residual stresses built into them. Over time, and cycling under load, those stresses to be "relieved," thus, the spring loses arch and spring-rate.

Get a new spring pack.

And avoid these shade-tree mechanics, who don't understand metallurgy.

So you're saying i should order it from vbp and then give it to Chuck to install? He does good work and all, but don't you think that this is an install that I could handle on my own with a lift, some new bushings, and a few wrenches or am I way off on this? (I've never done this before)

I bought one from corvette america at the PA car show. It was 117and free shipping. I installed it and it made a big difference. The car sits a little higher.

Check a couple driveline shops around your area. They just might be the same price or cheaper for a new spring.

If your handy with tools you can do the spring swap yourself it's relatively easy to do, just follow the instructions they give you with the new spring. I pulled my 7 leaf FE7 spring and put in a VB&P 360 lb monospring in about a hour.

How is the 360lb spring? I was thinking of going with a 340lb composite for the '79.

Also, is it true that you need different rear shocks for composite springs?
