Pull axle from 40 Rear
 

I need to pull the left axle out because the surface the rear wheel bearing rides on is deeply pitted. Can the axle be pulled on the banjo rear without tearing the whole differential apart?

no.

Basically no and a huge job.The whole ring gear assy with axles can come out the drivers side.BUT,you have to support the frame & rear with jack stands,remove both drums,dismantle the spring shackle (dr side),disconnect radius rod,unbolt left housing from banjo.Then slide it out past the axle.The axle assy will then come out.The carrier assy will have to be taken apart to get the axle out.You need lots of room on the drivers side to get it all out.I have done it once this way and its a pain working on your back.Easier to pull or drop the rear down.

Whoa.

The pitted surface you are referring to is on the surface of the axle housing, not the axle. You can't repair it without access to machine shop facilities. It is feasible to remove just the left axle housing half and leave the remainder in place, but it is difficult and frankly, not really a job for someone who is not familiar with this sort of job.

That said, these old cars will tolerate some pitting in this area without any major problem. It depends on expected usage, mileage per annum, speeds, loading, extent of pitting, etc etc.

It might be that you are worrying about a job that may be unnecessary.

As Mart states, the housing has nothing to do with the axle. In the Model A world they sell kits to repair the bearing surface. The kit is a sleeve that must be taken to a machine shop as Mart suggests and the axle tube where the bearing rides is cut down and the new piece is ether pressed on or attached by shrinking the housing and expanding the race. The now out of business Job Lot sold them as PN B-4012, you might be able to source on from some other supplier. If Model A is the same size, you can get the part from Brattons.

Incase you have not seen pictures of how a banjo rear comes apart, or goes back together, here are some pictures taken during my last banjo rear rebuild. Both axles, the ring gear, carrier housing with spider gears, must come out of the housings as an assembly. Then that assembly needs to be taken apart to access the individual axles.

Edit: After rereading the first post on this thread, and some of the replies, it appears the op is calling the axle housing an axle as was the case in this previous post that caused confusion for those trying to answer the original question.

No.... the pitting is on the surface of the axle where the rear wheel bearing rides.

The rear wheel bearing rides on the axle housing, where the bearing race is located.

Re: Pull axle from 40 Rear
 

Unless we are totally misunderstanding what you are referring to, it's the axle housing, not the axle itself. These are semi-floating axles and there is no bearing on the outside end of the axles. The axle taper connects to the drum/hub and the bearing is between the hub and the axle housing. No bearing on the axle, that is why it is referred to as "floating" on the outside end.

You should review the instructions for installing a Columbia 2 speed conversion.
I know a Columbia is not what you are asking about, but the instructions will show the steps required to do what you ARE asking.
Maybe Google or someone on this site can provide the instruction brochure.

How about a picture? Or maybe a thousand words? I am not sure what you are talking about? Where in general are you located, maybe someone could recommend a local shop?

Here are some pictures of axle housings and axles to help clarify terminology being used on this thread and your other recent thread on this same subject. Maybe you can post a picture showing the pitting you mention in both of these threads?

Re: Pull axle from 40 Rear
 

Didn't we have this confusion on terminology and the resultant clarification on another thread just a week or two ago?

Re: Pull axle from 40 Rear
 

JM, thanks for the photos. This should certainly clarify the bearing question.

Re: Pull axle from 40 Rear
 

Would you please post a closeup picture or two of this deeply pitted bearing surface you mention. This might help us understand the seriousness of this pitting.
