Hi Bedders,
I have recently installed a Borg Warner diff housing with a 2.9 ratio. I used to have a standard Bedford 4.7 diff and original rear end and could barely do 75 km/h. I am using the original Bedford housing and spliced it into the Borg Warner centre. The 2.9 ratio is excellent and very compatible with my wheel size and 173 Red motor and 3 speed auto. I can now cruise at 80-100 km/h and not have the nuts vibrate off every bolt. I am still running original (fully refurbished) drum brakes all round. The issue I have is that the left wheel axle needs to be about 15mm shorter and if I cut the spline shorter it is too short for my liking. Does anyone have any hints where to buy a shorter axle or a blank axle that fits the large Bedford flange for the original drum brakes? Any help is appreciated. Regards, John Forbes (Classic Rock Bedford rego 75 AC/DC).

28 spline borgwarner live axles run 22mm of spline into side gears with open centre, and have about 13 mm of unused spline so if you have about 20 odd mm of spline on your bedford axle left you should be fine.
