LOL, the passenger one has a bearing that bolts to the block, but it's not a concern. In fact, because of that bearing, the pass. axle is much easier to remove than the driver's. Just remove the axle from the hub, unbolt that support bearing, and she slides right out.
The driver side doesn't have any support, and as such requires a circlip to hold it in the trans, and is a PITA.
This "crum" guy seems to not have worked on these axles before.
And, I'm curious how you intended to inspect and service an axle while leaving it in the car on the curb, seeing as "crum" said it's "best to leave it in the tranny"
Do it right the first time. It's not hard. Just take it out.
