My very humble excuses, but I do not know how to correctly translate 'Hinterachsantriebsöl' . Rear axle drive oil?
I have replaced 'all' fluids in my recently purchased SW, with the exception of the oil that is in the drive system of the rear wheel. [Page 3-16 in the German 'Werkstatt handbuch' (workplace manual)]
I have checked the level, and it seems it needs to be topped up, but I wonder how to do this without creating a mess, since it is a tiny hole, and quite deep to get to, as well. Does one use a seringe, or a tube???
On a German SW forum, I read about somebody who used a thicker grade oil (75W90) instead of the advised 10W40. He claimes to have a more silent drive since he used the ticker oil. Is this a good idea, or should I stick to 10W40?
Thanks in advance for your suggestions!
