What size is the square on the Banjo (Differential Housing)? (Metric sizes are standard for us)
Thanks in advance

Bigger than 3/8", smaller than 1/2", probably 11 or 12 mm. The book says to use a 3/8 drive ratchet. It is pretty sloppy, but a 1/2" drive is too big.

You may have to grind down from the size to big.

The 3\8" breaker bar will usually lock in place and a tap with a hammer will loosen it. Most have been butchered up by people using channel locks or vice grips to loosen them. The suppliers sell a replacement that is actually 3\8" and the breaker bar and socket wrench fit correctly.

7/16", and if you find a 7/16" square head bolt, that and a Vice Grip usually work well.

I bought a cheap brand 1/2" drive extension and ground down the end to 7/16" square. Fits in and I can use a 1/2" ratchet to loosen and tighten the plug. Was a $5 solution.

Buy a piece of 7/16" key stock from a bearing supplier or industrial supplier like Graingers or McMaster Carr. Cut it into sections use one and give the rest to your buddies. Its cheap

A very intelligent solution. Smart thinking on your part !

I use the tool that came in the tool kit--- the tail end of the adjustable wrench

Yep, just an old 'shorty' extension. Ground it down to size and been using it for 50 years.

I had a VW lug stud laying around so ground it to fit the square.

I have been using a spare 3/8" for years.
