Help - Turn Signal Cancel Cam Replacement

I can't tell from the picture, but you have to push the *hub* type deal down to see the snap ring...we have a large "U" shaped tool that goes over the top of the shaft itself and pushes down on the outer edges of the hub thingy as you tighten it...you won't be able to push it down by hand, so you're gonna have to figure something out. I've seen Mo pin a big screwdriver against his chest to hold the hub down long enough to get the snap ring out, but he's 6'5 & 300...so I use a tool. Pop into a local parts store and look at a Hayes manual for any 60s/70s/80s Chevrolet...they're all about the same.

Your picture shows the top plate and snap ring already off. The top plate is what seats the upper bearing. I think there are 3 screws that hold the switch in at this point, you have to cycle the switch to get to all the screws. Unplug the flat plug on the wiring harness at the bottom of the steering column and give a yank, but first hook a wire or string to the wires to use when you install the new switch and want to feed the wires back down.

Good luck.

I think you hit the nail on the head. The top plate and snap ring is missing. No wonder I couldn't complete that step.
Thanks for all the input!

That top plate is what locks the steering wheel when you turn the key off...

I've found it's sometimes a good idea to disconnect the horn whenever you're working in this area. . When dicking around w/ the re & re of the related parts, it's hard not to make horn ground contact a few times and the resulting honking also zap spots on the contact surfaces can be avoided. ~ Pete

Well I found what the deal was. I need a Camaro part so I stopped out by Ron in McHenry looked at another steering column.

What I realized is that I had taken the plate and spring out earlier. There was no snap ring holding the plate and spring. Someone had put things back together without using the snap ring.

So now where do I get a snap ring to go back on the column?

You're talking about a very common inexpensive part,used from 1967 all the way up to today on nearly every single GM vehicle.
Contact any GM Parts dealer.Ask for part #5694191..later superseded by #580074.Either one will work.
It's a small wire C-Clip that a Hardware store most likely would have as well.


I think it costs all of 15 cents.
