While I'm waiting on parts to arrive, I thought I might try to replace the spark plug. Do these plugs come pre-gapped or do I need to buy a gap tool?

From an engineering point of view the best solution is open grease tapered roller bearing with grease seals
Next down the list is open bearings with grease seals
then metal shielded bearings with grease seals
and the worst is dry with a 2rs bearing
But the worst is also the cheapest .
Now the bearings ( if installed properly ) fail either from running dry or water getting into the races emulsifing the grease & again running dry
Filling the cavity between the 2 sealed bearings goes a large way to preventing water getting in and definately prevents water condensing from the air
The rubber sides are actually SHIELDS not seals and they are designed to prevent the grease in there getting out, not dirt & moisture getting in .
Metal shields are designed to prevent solid objects getting in while allowing grease or oil to flow through

Now the EPA in Cal does not allow greased bearings because of the pollution from excessive grease droping off the mower into the grass so the Cal versions must have sealed non greasable berings .
That last statement was a shocker to me. I wonder what other equipment has he same restraints in California. Landfills full of old worn out metal parts cannot be a better idea!

Speaking of spindles, can anyone tell me the difference between JD partACU131511 and AM14424. They’re both spindles. One is $140 the other is over $300🤔

I would encourage you to look at the spindles on Amazon for $27.99 each. They look identical to the OE spindles, plus they have a really good review rating.
