A good idea - though the Genuine BMC diff pinion tool Pt No: 18G34A has four pins to hold the diff flange against rotation.

If I were to make something specially for this purpose, I would take a suitable piece of (scrap?) plate about 8-10mm thick, drill and tap 2-4 holes (on flange bolt hole centres), make one 1/2'' (or 3/4) square hole for a breaker bar and drill/bore a central hole (big enough for a suitable socket). 2-4 high tensile cap screws (and nuts, if you want to go overboard). Job done.

Those without more than a drill and erhaps an angle grinder could drill a couple of holes, to bolt a long strip of steel to the flange, and grind out the side (or end), to make clearance for the socket as necessary. Job done. Or as taupe says, too, as long as the dexion is substantial and not the flimsy items marketed under that generic description.

I most certainly wouldn't be spending about £31 for a spanner, like that, which would hang on the garage wall virtually all its life!

The majority of tools are used infrequently.
But if you want to do the job properly, safely and without much effort having the right tool(s) is much better than struggling.
Non of my tools can be classed as 'nice to have' they all get used - some more than others.

Not sure if Dexion would be strong enough, but a length of angle iron certainly will do it. Crazy to spend all that money on tool for probably one time use.

Hi guys
I have changed a couple of pinion seals and have used the tool in the attachment. It is made from 65 mm. X 6 mm. flat bar 400 mm. long drilled for two bolts to secure to pinion flange. With the car jacked on stands the bar is rotated so that it contacts the ground. My torque wrench is a 'Williams Aoto Torque Wrench'. When I try to apply the 140 lbs/ft torque to the nut by pulling down on the wrench I only suceed in lifting myself off the ground. Because this torque wrench has an overcentre toggle action and also has a ratchet action I can set it up and moving outside the car and griping the underside of the guard I am able to use my foot to apply the 140 lbs/ft torque to the nut.
