I have to confess I know nothing about these. Can someone educate me please?
I'd like to buy one for my old Offroad but I'd like to make an informed decision before parting with my cash. The current (to be replaced) cup & cone axel is stamped 68 (assuming that's the shell width?) and 122.5 (which is the length) but what are the differences between a CT21 an LP27 a UN40 a UN51 a UN52 a UN71 a UN72 and a UN91?
