How To Recondition a Sure Grip Cone

Just want to clarify a couple of things. Yes, .100" is probably the absolute max you would ever want to remove. Reason I did that was because both cones were worn sufficiently that they bottomed in the case halves really badly. Once the cones contact the case ends, all bets are off, the limited slip function is gone.

The cones grip the case on the outsides, where they are threaded. Once they wear to the point they contact the case ends, they can no longer engage the sides. That is also why I added the shims to this one. Sometimes the shims are not needed, or a very small amount.

The shims are usually only to restore spring preload, but this one was worn so badly that the shim function also had to include moving the side gears back into the spider gears.

As I said from the beginning, this is not a boni fide recommended repair. You are taking a chance because you are milling away a small portion of the splines on the cones. They could possibly strip. But, if they do strip, it is likely the unit was being asked to do something that it shouldn't anyway.

I am glad those of you who enjoyed this did. Thank you C for cleaning up the bickering. It serves no purpose other than to dilute the thread. The whole purpose of this was to show that you can restore the sure grip function and use it again in a mild street application. It sure beats buying a new 400 buck plus unit.

Lastly, if yall want to discuss why this isn't a good idea, or your own ideas or any disagreements, please create a thread for that. This was meant as a how to thread to add to the tech section, not an argument and discussion thread. C worked real hard cleanin all this up to look presentable in the how to section. Lets not make more work, ok? Thanks.

Thanks again, C.
