While debugging *why* things went bad in the post-engine drive train (and bad did happen, including needing a new clutch bell housing), I opened the rear end to insure that all looks good in there. I did notice the ball bearing assembly which holds the Final Drive Idler Gear seemed a bit grittier than the rest.

Before I "fix it until it is broken" - how difficult is it to pop out these bearings and reinstall new ones?

(although I would hate to put it all back together and send it to the shop, that is a possibility as well)

It's simple and easy with the right tools. This past month, I replaced all those bearings.

I bought the Slide hammer set from Harbor Freight with a 20% off coupon.

Best of Luck!

That harbor freight tool is exactly what I used to remove mine. Use the secound smallest wedge. It just barely fits and the smallest one will slip out.
I have extra bearings if you need one. I can drop it in the mail. Let me know.

And use plenty of heat on the casing around the bearing. But you must use a heat gun, not a hair dryer. The trick is to heat quickly. You almost don't need a puller at all. I never use one, just heat. They all just pop out on their own once you know the technique. But it's always nice to have the puller to hand just in case you get one that is stubborn.

Thatís a cool photo. Presumably the oil drain is in the side thatís been removed.

How does the oil get up to the top gear/bearing? By splash and adhesion from the lower gears?

Your right, it is all just splashed lube. There is no pressure applied to the oil, it is just like a car differential
