As part of my suspension swap over I needed to drop the front diff 20mm (any more would start reducing clearance and defeat the object really!). Why? With the front lifted 50-60mm without a diff drop there will be accelerated wear on the CV's and greater torque steer when pulling away hard, especially up hill. Even just a 20mm drop will put the CV's at an acceptable angle plus improve the CV angle at full droop.

I looked at a spare OEM cross member and considered cutting it up but decided that would be plan B and plan A would be to make a new cross member. Below is what I came up with.

Starting with some 120x60x5mm box section:

I used the OEM part as a template and just cut the box section to put the mounting holes 20mm higher up:

Then a bit more cutting and some 50x6mm flat to close it off:

Cut and folded some plate to make the diff mounting:

All stuck together with an extra plate down the back of the diff mounting same as the OEM version:

Even gave it a coat of paint and turned some spacers for the other 2 mounting points :)

Works a treat, just got to finish some more spacers to be able to refit the OEM bash plate till I have time to make one of those.

Good guide Jon.

I'm reading your guides with interest because my next Cruiser may well be a 100.

Thanks for taking the time to write it up. :mrgreen:
