Good evening, i believe the gasket on my rear wiper motor is leaking as i am getting a trail of water running up the inside of the tailgate glass when i fully open the boot. Does anyone know the part number of this item, (No.4 on pic) and can it be changed without removing the wiper motor or does the motor need to come out to replace the gasket.

Thank you.  

I had similar and water pooling on the rubber boot seal.

 

From what I could tell the water was getting in between the rubber seal and the glass rather than the rubber seal and the wiper shaft.  This was backed up by the fact that the hole in the glass could be felt just underneath but very close to the edge of the rubber seal.  I managed to gently pry the rubber seal up slightly and work some windscreen sealant under it.  No more leaks...

Thank you for the reply. I’ll have a check of that when i get chance to see if it just needs a bit of sealant as opposed to a new gasket. 

I'd say just put some silicon sealant around the seal.
