To try and solve the problems described in the last post with the rushed setting of the side cogs I'm refreshing the original differential so I can put that back on the car and keep myself driving something I own!
This is a pain in the arse to be perfectly honest but it does give the opportunity to learn. I can for example compare the heights of that dodgy pinion crush washer => New is on the left
The height difference is about 1.5mm - so that's how far you go when you apply 7 tons of force (see previous post - I'll say if I have to apply the same or more this time)
