3. Measure the clearance between the rear axlebump pad and the bump stop rubber at the
front outer corner on both sides of thevehicle. The average clearance should be inexcess of 67mm (2.8 in). If it is less than this
figure remove the rear springs and check theirfree length against the Road Spring Data.
Replace any spring whose free length is more
than 20mm (0.787 in) shorter than the figure
given. If after replacing a spring the averagebump clearance is still less than 67mm (2.8 in),
replace the IevellinR unit.8 .

Reverse items 7 and 6 as applicable.Reverse items 1 to 5. Vehicles up to 1990Model Year - when fitting the top shockabsorber fixings compress the mountingrubbers and locate the cotter pin in theINBOARD hole. The outer hole is NOT
designed for this purpose.
LEVELLING U N I T
Functional check
A Boge Hydromat levelling unit is located in thecentre of the red. .-.le.When the vehicle is unladen the levelling unit haslittle effect. The unit is self-energising and hencethe vehicle has to be driven before the unitbecomes effective, the time taken for this tohappen being dependent upon the vehicle load,
the speed at which it is driven and the roughness
of the terrain being crossed.
If the vehicle is overloaded the unit will fail to level
fully and more frequent bump stop contact will benoticed.
Should the vehicle be left for a lengthy period, e.g.overnight, in a laden condition, it may settle. This isdue to normal internal fluid movement in the unitand is not detrimental to the unit performance.

With the rear seat upright, load 450 kg (992lb) into the rear of the vehicle, distributing the
load evenly over the floor area. Check thebump stop clearance, with the driving seat
occupied.Drive the vehicle for approximately 5 km (3miles) over undulating roads or graded tracks. . ..Bring the vehicle to rest by light brake .application so as not to disturb the vehicleloading. With the driving seat occupied, check
the bump stop clearance again.If the change in clearance is less than 20mm(0.787 in) the levelling unit-must be replaced.
Before carrying out the checks below, verify that
the vehicle is being operated within the specifiedmaximum loading capabilities. If the levelling unit is
then believed to be at fault, the procedure below
should be followed.
1. Check the levelling unit for excessive oilleakage and if present the unit must bechanged. Slight oil seepage is permissible.
