●When installing rubber parts, final tightening must be carried out under unladen condition* with tires on
ground.
●Oil will shorten the life of rubber bushes. Be sure to wipe off any spilled oil.
*: 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.
●Disassembly and service location must be taken 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.
