Spanner Sizes for LC100

10mm hex key to drain/check front diff.
24 mm socket for gearbox/transfer and rear diff.

I've been servicing L/Cruisers for 25 years, I have never used a 10 hex key to check or drain the diffs.

Instead of a 24mm I use a 15/16 socket with the round lip ground off, this enables the socket to sit on the G/box, Transfer, and diff nuts better.

You will also need a 12mm and 14mm socket to adjust all belts, the sockets make the job easier.

If draining the Diff, G/box or Transfer loosen the filler plug first, if you can't loosen that plug do not proceed with the drain plug.

Cheers Steve.

add 22mm for wheelnuts and a couple of other bits

Steve,
the front IFS diffs need a 10mm Hex. I expect that you've just had the rigid front models.

"8, 10, 12, 14, 17, 19 will get you there."

- same for a Pajero.

yep 15/16 is 1/2 a bees dick smaller than 24mm and has less chance of rounding off those infernal thin diff fillers.
from memory the tool kit comes with the spanners to do most jobs
