Now for something a bit diff..erent!!

One of those frustrating days on Tuesday where me and the old man spent all day in the garage and didn't really have anything to show for it. Basically fitting the diff to the chassis did not yield the results I anticipated. I fitted the diff but the brackets would not line up nicely.


So after a quick call to Andy at GD who said I was doing it all wrong, and a subsequent chat with Simon (fellow GD builder) I decided to abandon initial diff fitting and build the rear axle up off of car.

Once built up the assembly is fitted and the chassis may need to be helped to fit with a sturdy bar!

With the diff now placed at a more workable height on my temporary bench I was able to trial fit the jag pivot brackets to the diff without shims. This showed me that the rear GD diff bracket fitted perfectly but the front one did not.

I tried 5 thou shims one each side which improved the front fit but it would still not go on. Eventually 10 thou on each side enabled the front bracket to fit but now the rear bracket wont go on.

10 thou worth of shim's


A bit more shim fiddling and Ive wound up with 12 thou on each side at the front and 7 thou on each side at the rear, most importantly both brackets fit and the shafts turn relatively freely.

The thinking being that the GD brackets have been drilled to suit the original jag shims, so that should have set my carrier brackets somewhere close. Next thing to do is to fit the discs and calipers setting their shims as I go. I can then fit the lower arms, hubs and drive shafts and sort hub camber. Once all this is done Ill probably drop the calipers off whilst I set up the rear toe in and thrust on car. Once all is set Ill remove the assembly, refit the calipers, lock wire the carrier bracket bolts and caliper bolts ready for final installation.
