naw my car is at home. im in afghanistan for a couple more months. would it be easier to just get another MFS and brass ring and just replace them both? or is the canceling-cam a seperate part? do u have any pictures or diagrams that would help? once i get home ill break it all down, was about to just order another steering column or airbag off of ebay good thing i found this post.
Hey Syrus, I'm surprised to see this old threat dug up! I'm sure I can help you with any info. I have some pictures on my phone of the steering column from the top before I disassembled it. It only really shows the cam signal cancel well and not all the fun and important parts of the column itself.
The brass horn contact ring is attached to the cam signal cancel and is all ordered from the cam signal cancel. Before you go and replace your MFS, what is the problem with it? If it's just that your turn signal isn't turning off then the problem may lie entirely in the cancel itself. It's also possible the canceling mechanism inside the MFS is gunked up and not working correctly. I took apart my gf's MFS in order to clean what I could and used a little grease to ensure it all worked smoothly. It's not difficult to tear down if you don't mind, but if you don't want to worry about it you could always just replace it.
The hardest part of the steering column tear down was the steering wheel. I rented a puller from Autozone (a small one IIRC) and the holes provided to remove it are terribly small and didn't line up with the puller I got. After examining the wheel better my friend and I detached the rear cover portion of the wheel and used points on the outside to remove it easier. This may be confusing because I'm doing this from memory but if you got pictures and had trouble we could assist.
I don't remember if it's mentioned earlier but I also had to rent a steering wheel lock plate tool to remove the plate just in front of the cam signal cancel. If you had the correct GM tool it would work tons easier, but the rented tools metal U bracket was too wide and I had to work with it by placing one side of the U on the plate and use a flat head screwdriver on the other side in order to compress the spring far enough to take another screwdriver and remove the retaining ring.
Those were the only two difficult parts really and it isn't as bad as it sounds. Patience and planning are key. If you need any help when the time comes to do this just post again. Good luck!
