Axles
Regular Land Cruiser axle housings are similar to a Ford 9" and differential carriers are similar in construction to a Chevy 12bolt. The front and rear differential housings are both offset to the right in all models except some '58-62's which were centred. They have an 9.25" ring gear. The axle shafts are 33mm in diameter (the same as a some Dana 60's) 1960-67 shafts had 10 coarse splines while 68 and later shafts have 30 fine splines. In 1968, the front axle CV joints changed from ball joints to Birfield. Full Floating Axles have smaller shafts because the entire weight of the truck is bourne by the wheel bearings and the shaft itself is not loaded in flexure.
Light Duty axle housings are the same as those used in Toyota Pickup trucks. They feature a smaller housing constructed similarly to the heavy duty Land Cruiser. The ring gear is only 8" but the axle shafts are the same size and have the same number of splines as the regular Land Cruiser.
60/2 Series axles are 70mm wider than 40 series.
70 Series axles are 20mm wider than 40 series.
