how to stabilize my stablizer?

Well, after 9-1/2 years, our 100-400L IS seems to have given up the proverbial IS ghost over the last couple months. Up until recently the IS would occasionally flake out and shake the image for a second or so, and then resume normal operation (while malfunctioning it would make some rather strange alien-like sound effects; quickly resuming the normal slight metal ball rolling sound I have become accustom to with this lens).

Recently the length and frequency of these occurances has increased dramatically, the sollution was when it annoyed me too much i would just turn off the IS. well, that doesnt work anymore. weather the switch is on or off, mode 1 or 2, it still acts as if it is on 100% of the time on mode 1.

sooo; my lens has become all but useless. 80% of the time it is jarring the image at near light speed, and it is impossible to frame anything. Anyone ever delt with somthing similar or know the approx repair cost? this lens has seen it all, and isn't a spring chicken anymore, it has pretty much no decernable markings on it anymore, all but the sealed numbers inside the range meter have worn off from use. (i'm trying to decide if i want to hock it, repair it, or replace it)

-btw, im not even frustrated by the problem, i feel the lens has well outlived its normal use and served me well.

Given the price to replace, the repair is usually well worth it.
I suppose it depends, but I've read of IS fixes on that lens for under $200.00

Canon USA will likely give a price to bring it up to spec,. which will be higher,. but still. Vs. $1400.00 or so for a new one?
