Re: [AMC-list] overdrive issues

Yeah like Tom says, wobble is normal....
Specially in the old stuff newer ones seem to be tighter.

If that howl started after you started driving it, I'll bet you have a bearing going, huh, somewhere...

trick now will be to find it! It can be tricky to isolate a bearing howl in an assembly.
Chased one in an XJ clear down the front pinion bearing before finding the bad one. What a PIA that was!
Spend a lot of time checking every race and bearing you can with what you have apart.
Don't rule out a chipped gear or those spiders either.

Without seeing the input we can't really hazard a guess, it could be a bad bearing.
You can swap shafts, usually, worn gears from different trannies can make noise, but it is usually very mild and does no real harm.
just alight whine a little louder than normal new stuff. 

Hope you get it sorted out.

CHECK the pilot bearing in the crank! You never know, even if it was new, doesn't mean it is good NOW!

The shaft does normally wobble in the case. It's a single row ball bearing.
Remember that the far end of the input shaft lives in the pilot bushing;
that's what keeps the shaft rigid longitudinally.  It's also why
transmission alignment is so important.
