A typical time spent with an old Land Rover: a selection of rusted nuts, bolts and washers, all in various states of damage and corrosion - all to be replaced with brand new ones, thankfully.
Test fitting of the front axle casing on the new springs. Good thing I tested, as it turns out the dowls that center the axle are not exacty in the middle, from front to back (not side to side). On each front spring, they were off by about 3/16, both in the same direction when reading the stencilled words on the springs. Not much, but when I had the springs initially placed with the stencilled wording facing outwards on each side, it was visible, by comparing with the chassis, that the axle had a very slight 'turn' in one direction. By making the springs identically placed, i.e. with the stencilled wording reading from the driver's side, on both sides, the axle lined up properly.
Have now made sure the rear springs are also identically placed.
