1948 to 1953 Land Rover axle changes
The Land Rover axles used Rover differentials and even though
they all remained similar a few changes where made over the years.
The differential ratios changed. They were 4.88:1
and are now 4.7:1. On the very top
of each differential, is a number like
LR 1009 F. This means it is 1009th front
Land Rover differential. Later vehicles
have number a similar sequence. The
differentials changed again at axle No.
The braking system changed quite substantially. They
were firstly Hydrostatic which
means they are self adjusting. The brake
fluid making the adjustment. The
hydrostatic wheel cylinders have a 1 3/8" bore
on the front and a 1 1/8" bore on the
rear. The brakes changed to being manually
adjustable with a snail adjuster on each
leading brake shoe. The bore of these
wheel cylinders are 1" on the front and 1"
on the rear. For those more interested
have a look at the parts books.
The differentials changed in many minor ways. The
bearings changed from roller
bearing to taper roller bearings. The
most visible difference is that driving flange
changed from being round and long,
to being square and short. The propeller
shafts were lengthened to make up for
the shorter drive flanges.
The top bearing of the swivel housing changed from
being taper roller bearing to being
a spring loaded bush style bearing.
The top swivel pins changed to suit the new
The front axle casing changed so that the spring seat
is now 2.5" wide having
previously being 1 3/4" wide to be
in line with the 2.5" wide springs that became available from
