I've got the 8 1/4 axle, that one is for 8 3/4 and DANA 60. Year One has one for half the price, but doesn't list what axle it is for - LinkThey can be had for a few bucks for modern MOPARS, but is it the same part? - Link

Am I going to have to do this to grease the bearings? It doesn't look hard, if you've done it before, but I haven't, and I'd have to take down part of my wall.
It might be wiser to leave things as-is and bump a new rear end up in my list of priorities.

What point in the video are you asking about Jeremy? Give me a minute mark to go by please.

Setting the ring and pinion backlash generally, I guess? No specific point.

that's really tricky. If you have to set the backslash that's pretty much easy, but not the pinion depth

So what do you think? Leave the diff alone? Drive it and see if the bearings are o.k. for now?

If the bearings were not noisy, and if you don't see an excess of metal in the old oil you drain out, then I would leave them alone. If it ain't broke, don't fix it.

If it ain't broke, don't fix it. agreed. is hard to beat the differential parts and when parts fail they are NOTICEABLE. Broken parts, debris, blueish metal. They can work for decades as far keep the lubrication. When times to come to the suregrip change, just will need to set the backslash when reusing the ring gear, and of course new carrier bearings, nothing else. Most of the times when axle bearings need to be replaced is because the outer seal failed, since the bearing needs to be destroyed to remove the outer seal and replace. Dunno on 8 1/4" axles is the same than 8 3/4", but on 8 3/4" uses to be like that. 8 3/4" axles also get more stress on bearings being tapered and holding side loads.

By the looks of the diff I believe the bearings stay in the axle tube and axle are held in by c clips. If you're concerned about initial lube on the outer bearings I would pull the axles out inspect them and if they look good work some grease into the bearing and replace the seals. As stated those bearing are pretty tough and usually only fail if there was a leak resulting in a low fluid situation.
