Land Rover Discovery: Ball and Roller Bearings
When removing and installing bearings, make sure that the following
practices are observed to make sure component serviceability:
CAUTION:
Service tools have been developed for removing the majority of
bearings; these must always be used where specified.
- Remove all traces from bearing under inspection by cleaning with a
suitable degreasant; maintain absolute cleanliness throughout operations.
- Conduct a visual inspection for markings on rolling elements, raceways,
outer surfaces of outer or inner surfaces of inner rings. Reject any
bearings found to be marked since marking in these areas indicates onset
of wear.
- Hold inner race of bearing between finger and thumb of one hand and
rotate outer race to check that it revolves absolutely smoothly. Repeat
holding outer race and rotating inner race. DO NOT spin the bearing.
- Rotate outer ring gently using a reciprocating movement whilst holding
inner ring; feel for any check or obstruction to rotation. Reject bearing if
movement is not absolutely smooth.
- Check bearing for blueing or signs of overheating.
- Lubricate bearing with the specified lubricant.
- Inspect bearing surface of shaft and bearing housing for discoloration
or
other markings which indicate overheating of bearing or movement
between bearing and seating.
- Before installing bearing, make sure that shaft and bearing housing are
clean and free from burrs.
- If one bearing of a pair shows signs of wear, overheating etc., it is
advisable to replace bearings as a pair unless it is suspected that one
bearing may have been faulty when installed, was installed incorrectly or
the fault arose due to oil seal failure.
- Never reinstall a bearing unless it is in a fully serviceable condition.

- When installing a bearing to a shaft, only apply force to the inner ring
of
the bearing. When installing a bearing into a housing, only apply force to
the outer ring of the bearing.
CAUTION:
Service tools have been developed for installing the majority of
bearings; these must always be used where specified.
- In the case of grease lubricated bearings, fill the space between the
bearing and outer seal with the recommended grade of grease before
installing the seal.
CAUTION:
When a waxed oil seal (installed dry) type of oil seal is to be
installed,
take great care that grease does not contaminate the running surface
of the seal.
- Always make suitable reference marks between the components of
separable bearings e.g. taper roller bearings when disassembling to make
sure correct location of components when assembling. Never install new
rollers in an outer ring, always install a new bearing assembly.
BRAKE PADS AND LININGS
Always install the correct grade and specification of brake pads and linings.
When replacing these items, always replace as complete axle sets.
