This blog documents the restoration, and conversion, of a 1965 Humber (Singer) Vogue to a fully electric vehicle. The Vogue will be powered by an 11kW(modified), 3 phase industrial AC motor, controlled by an industry standard Variable Speed Drive (VSD) or Inverter. To be able to produce the 400 volts phase to phase the VSD will need about 600 VDC of batteries. A big thanks to the contributors on the AEVA forum:

Changing the Differential Pinion Angle

My spring wedges (sounds like a potato treat with greens), arrived yesterday so last night I set about separating the axle from the leaf spring on one side of the car. I jacked up the car under the diff housing then placed the two rear body jacking points on axle stands. Then I lowered the jack until it was only just supporting the weight of the rear diff/axle.
The U clamps came off pretty easily (with the aid of some CRC56).Once the U clamps were off, I jacked up the axle slightly to removed the top rubber mount.

You can see the leaf spring centre pin that locates the spring on the rubber mounts (next photo).

A slightly blurry picture of the U clamps, upper and lower spring mounts and shiny new two degree wedge.

View from the rear of the car.

The spring wedge in the upper insulator/mount. The upper rubber insulators are not in very good condition but I tried unsuccessfully this morning to get new ones. I'll put these back in and keep trying to find a replacement now that I know how easy it is to "drop' the rear axle. I think I'll make a thin wedge to go in that gap in the wedge as well.

The left hand side - still intact. I'm doing one side at a time. That way the "other" side holds everything in place and I don't have to worry that the whole axle will fall out on the floor - tearing the brake lines in the process. The oil stains are an old testimony to (now-replaced) leaking rear oil seals.
I'd love to pull the springs out and clean the whole lot up but I want the Vogue back on the road ASAP. Maybe next year...

A couple of paragraphs from the workshop manual. It's interesting that Mr Rootes sometimes fitted wedges. No, I didn't find any.
