Anything is possible, but installing the spring incorrectly is hard and would require a concerted effort on your part. Springs can get weak, not very often and it's usually a metal problem. If you suspect your spring is bad, new ones from the factory are inexpensive (and if you describe the problem to them, they might send you one free), aftermarket springs are available from lots of places, just visit some of the advertisers on this site. Okiegunsmithshop.com has an exploded view of the Contender on their web site. Your owner's manual should also. IF you don't have one, all you have to do is call TC and they'll send you a new one for free. They'll also send you the latest exploded view and parts list (with prices), free. So don't buy the one for $5 the guy is trying to sell on e-bay

. I've got them scanned in if you need it fast. Just send me an e-mail address and I'll send it to you, but they're almost 3 megs total so depending on your connection it could take awhile to download.
