Hi, PhilC.
I don't have any figures to quote but I think that even with planetary hubs included, your figure would be a lot closer to reality.
Just my 0.02.
Hello Deas
Sorry I forgot about this thread.
I picked up the axle today and I weighed it when I got it home and it is 2700 pounds or 1230kg without wheels and each wheel weighs 330 pounds or 150kg. The 2700 pounds includes about three feet of chassis.
Regards
Phil
