Drive shaft casing
« on: July 09, 2020, 07:15:05 AM »
 :152: Hi, I'm sure this must have been discussed many times before on the forum,
but re  " Final Drive Casing Corrosion :
Look for peeling or bubbling black paint indicating that the underlying alloy casing is corroding".
 
Being a new owner I have noticed how rough the paintwork is on the end of my drive shaft casing on my new 2013 TT, is there anything I can do to see if there is a problem?
Thanks for your input

Hopefully it's just surface corrosion, if so, lightly sand heavy corrosion (wet and dry 220 grit)  then use some type of aluminum etch (like the one at the link).
Completely dry area and apply an aluminum primer, followed by some type of black enamel paint.
This should stop any further corrosion, at least in that area, from getting worse or taking place again.
