 PRECAUTIONS

PRECAUTIONS PFP:00001

Caution EDS00060

● When installing rubber parts, final tightening must be carried out under unladen condition* with tires on
ground.
*: Fuel, radiator coolant and engine oil full. Spare tire, jack, hand tools and mats in designated positions.
● After installing removed suspension parts, check wheel alignment and adjust if necessary.
Observe the following precautions when disassembling and servicing drive shaft.
● Perform work in a location which is as dust-free and dirt-free as possible.
● Before disassembling and servicing, clean the outside of parts.
● The disassembly and service location must be clean. Care must be taken to prevent parts from becoming
dirty and to prevent the entry of foreign objects.
● Disassembled parts must be carefully reassembled in the correct order. If work is interrupted, a clean
cover must be placed over parts.
● Paper shop cloths must be used. Fabric shop cloths must not be used because of the danger of lint adher-
ing to parts.
● Disassembled parts (except for rubber parts) should be cleaned with kerosene which shall be removed by
blowing with air or wiping with paper shop cloths.
