Replacing rear axle seal, what else should be replaced?

[WannaCruise]

Hello all,

While diagnosing an ABS/VSC TRAC/VSC OFF/BRAKE error, I found the passenger side rear axle was leaking. I removed the ABS sensor and found the sensor coated in diff oil so I need to plan an axle reseal job. In searching for solutions, I found Timmy the Toolman's video on replacement and he lists all the parts needed to properly reseal the rear axle. Are ALL of these items required for a reseal, or is it a matter of replacing "while you're in there"? The parts are:

Qty: Description Part Number
(2) Inner Housing Seal 90310-58002
(2) Inner Retainer 42423-60030
(2) Outer Retainer (Optional) 42423-60040
(2) ABS Tone Ring (Optional) 43517-60020
(2) Snap Ring 90520-44038
(2) Washer 90208-48002
(2) Bearing 90369-48001
(2) Axle Housing O-Ring 90301-85004
(2) Outer Oil Seal 90313-62001
(1) Rear Diff Breather 43209-60050
(1) Parking Brake (DS) 46580-60050
(1) Parking Brake (PS) 46540-60050

Is there anything else that I would need, or are there any of the above parts that are not likely to be used?

On a side note, the total price via one of the Online dealers, along with the current 15% discount, is $529, no tax, free shipping. The Impex cost is $269 + shipping/tariff/duties/etc. I might roll the dice with Impex again...

are you replacing the bearing because it was washed out by gear oil? if your bearing is still ok, that parts list can be cut in 1/2

Not sure if the bearing is bad or not, but there was significant oil on the ABS tone ring and speed sensor. There was enough to cause the ABS/TRAC/BRAKE errors.

Is it OK to just replace the seal, or is that a bad idea on a 20 year old truck with 180k miles?

Just replace the bearing and call it done, bearings will fail at some point. I hate to see you posting again for a bad bearing after all that work.
