Noisy wiper motor!

This has happened relatively quickly.
Took the car out today and the heavens opened. The wiper motor was really noisy and it wasn't the wipers on the screen or the rack.
I put a screwdriver on the motor and it is almost certainly the bearing.
The black armature housing is spotless as is the armature itself. No water or dirt.
I greased the end of the shaft that goes in to the bush in the end of the housing but still the same.
It always seemed noisier than most cars even when I first got.
Is replacing the bearing a doable proposition or do I risk buggering it up??
Also what is the purpose of the black plastic nipple in the side of the casting/gearbox?
Please tell me I can pump oil/grease in there and have a 2 min fix! It looks to be below any electrics.
Yes I know that is like a snowflake in hell.

Rimmers want £220 for a new motor.
Any help or thoughts would be most welcome.
 

You certainly could buy new bearings for them & I cant see that having changed. I don't recall it being a difficult job to strip the lot down, greasing the gear chamber en route. They weren't the finest example of the motor builders art but when you remember how many millions of them & their close relatives there have been made, for all its crudeness, the design has to be admired.

I vaguely remember someone saying that a wiper motor for another Rover or LandRover vehicle was physically the same but just needed rewiring to make it work on an F / TF. Unfortunately I cant remember which vehicle or what the mod was that is needed though.

It could be worth a Search and a Google.

I posted about having a noisy wipers motor a few months ago and AP recommended that I strip the motor as it could be full of crud.
He was spot on. 

Thanks for the pics.
Mine was totally clean inside so I think it is the bearing.
Pain in the ass!!
I have sprayed grease in to the gearbox with a vain hope it droos on to the bearing..which is probably sealed anyway.
The last time I used the wipers I never really noticed anything untowards.
This time you couldn't miss it.

Unless you know what alterations are required for using the Freelander motor, I would consider an alternative approach; stick with the original pattern or rebuild what you have.
Our cars use a simple switching arrangement, whereas the Land Rover utilises electronics.
On day I’ll find a buckshe unit & work it out, for the general good!(how pompous does that sound).

Not pompous at all..helping the greater good..and helping me!

There is a complete assembly from seller coopersteve1 on ebay for £41.24 if you fancy bench stripping refurbing etc.

Be careful with Freelander motor as it is important which version of Freelander motor you are using and at which wiring. Just word of warning.

Thank you. That might not be a bad idea. My motor is in great condition apart from what seems to be a bearing and that won't be expensive. 
if I practice on a s/h one I should be able to keep my original motor! 
 

I've just learned what the black plastic grub screw is for!
By fickering about not knowing what I am doing I found it takes the play out of the armature spindle.
My spindle was wobbly and I did wonder if it was clattering the magnets as it spun but the bush in the end of the spindle should stop that and there were no signs of rubbing.
Anyway, adjusting the grub screw takes the play out of the spindle and stops the wobble.
I'm sure you guys knew that but I only found it by blundering through and sheer luck.
