correct me is f I'm wrong is the differential bolt thread pitch 18x1.5?

 

anybody

 

help

 

Bueller?

 

 

 

ps: I tried doing a search but couldn't find an answer for you.

 

Just so this information is out there, i believe the diff drain AND fill are M16x1.5, that's what most 24mm head bolts are.

i am double checking on my spare diff later tonight.

i hate to bump an old thread but it's not on S2ki and it needs to be.

 

I think everything is 1.5mm thread pitch on this car is it not? And having just changed my diff fluid, it is 24mm drain and fill bolt. Not sure about 16 or 18 though.

 

No there is plenty of other thread pitches.
Fill bolt is 23mm and drain is 24mm, it's the same threads though but good to know or you will eventually round off that 23mm bolt if you use a 24mm spanner.
