How to reduce sidefumbling?
I’m replacing and rebuilding the swerving bearings (just the two direct-line bearings), and I was wondering if anyone has considered the possibility of reducing the common sidefumbling problem if the milphertrunions are synchronized with the differential girdle spring when doing this? Or will this actually increase the wane shaft scoremotion? This, of course, would offset any gain, at least if you consider it logarithmetically. Anyone ever try this?
I expect half of the responses to agree that it's a great idea that takes advantage of 50 years of materials engineering, other half to scold you for doing something different than the way GM designed it.

Thanks for excellent responses, guys! Glad to see, and verify, that C3 humor level is where it's supposed to be, and that people have been watching the "Turbo Encabulator" video (the original as linked by 427Hotrod above)!! Proves you all as a bunch of technical geeks and nerds - you passed the test!
...now I actually do have to go to the workshop and remove that spring... Since you all understand the Turbo Encabulator concepts and are pretty smart on that, how many of you can identify the photo in my original post and know what the spring is for?
Because I'm late to respond, don't think less of me. It looks like your frizzenstat has become discombobulated and lost it's anti-sproing housing. But man I need a Drink after seeing how deformed it is.

The photo is of the Preload Spring for the clutch packs in a 1974 Pontiac heavy duty 8.5" Limited Slip differential ("Corporate" differential) as used with the 455 engines in the "F" body cars:
If you're not familiar with the preload spring on these cars, it can be very difficult to remove the axles since the preload spring partially covers, and retains, the axle C-clips unless it is aligned in the exact, required position for disassembly. Be glad you have a Vette...

Dr. Phil says "You need F@$@&*^ help" Good one though!!
