junk yard rear air struts

[revdowrong]

Hi, im a proud owner of a 91' cadillac deville and i was wondering about the rear air sturts. I recently went to the local junk yard here in san antonio and nabed some rear air struts off of a 93 ' deville that look like it had been well kept. So I inspected the air struts and the boots looked really good it showed no signs of cuts or puncture. So I guess i was wondering is there in way of telling if they r worth my time putting them on my car? and i was wondering if there is any other way to tell if these shocks are good befor i but them on my cadi. Oh yeah by tha way this cadi had atleast 113 thousand miles on it when the person junk it.

You have both age and wear working against you. No way to validate the internal parts. The JY usually guarantees that they are okay at time of purchase. Of course they don't compensate for labor if you have to take them back off. If you get them cheap and they last a few years, consider it a good deal.

Thanks for your reply its just i got lucky the first time when i got my front shocks from the pick in pull, wich might i add there where far beter than the ones i had. Now the first pair of rear air struts i got from the junk yard where ok. It turned out that one was good and the other was bad. So i made another trip back to the junk yard and saw another cadi so i inspected the air struts and they look better then the rest i saw, and far better than the first pair i nab. So this time i got smart and got an air compressor and air line from the boneyard, came home and hooked it up to my strut to see if they would hold pressure. to my surprise it did. When the shock was fully extended i check the boots for leaks or any wear and tear but they look as good as new.Well in a few weeks i will be putting new springs on along with the junk yard struts and i will post back soon on the results
