Composite Springs useful life?

[killain]

I was just wondering if anyone knows what the life expectancy is on the two composite springs at each end of a C-5, or any composite spring for that matter. The reason I ask is I had to have the front spring on my C-5 replaced today at the dealership, they had diagnosed it last week as having sagged. The car only has 10900 miles on it. And I'm very careful about potholes. I had a TRW composite spring on my 79 and it was perfect for years! Any opinions welcome.

Sagged?
I would think a sag would be associated with a crack or split in the fiberglas, and not just a loss of tension in one end or onother.
Many factors can affect a failure of fiberglas springs. Solvent or oil exposure being a couple of them. Over stressing a spring can cause it to delaminate, split or crack. Of course there is always the possibilty of a defect in manufacturing.
In general, it is what it is. Some last a long time, some fail prematurely. Who knows why without some sort of failure analysis being done.

My car has 127k miles on it and the springs have never been replaced. I'm with wishuwerhere82, there needs to be some failure analysis done to determine the cause of failure. The front spring on an '03 with only 11k miles should not need to be replaced at this point. How did the dealership determine sag? Did you go to the dealership for a spring problem? Is this dealership well versed in Vettes?

Poor service job at dealership

Well to tell you I don't know how they came up with that diagnose, but they had the car on the alinement rack for two days. " couldn't get the steering wheel to center correctly, And it still isn't correctly done and I took it back twice now." On top of that I had to rent a car in the meantime and if as if that was not enought, they left my car filthy with grease on the floor and on the kick panal and carpets. it just took me a hour to clean it up properly. It's sad, obviously the technician did not know how to use the "new" alinement eguipment at the dealership. Plus he broke off a piece of the radiator housing down by the left front wheel. I used epoxy to refit the broken fiberglass housing. I'm really discourged at the whole job. I know of a real good alinement shop about twenty miles from here and I'm going to give them a call and see if they can straighten out the alinement situation. This is the first time I've had a bad expierence at this chevrolet dealership?:confused

Which dealership did this work? Where are you located in SE PA? Perhaps a change of dealers is in order. Send me a PM if you don't want to broadcast that info.
