SECTION 2 ROUTINE MAINTENANCE Cont.
2.6 Every 6 months inspect ball joints for corrosion as follows :-
NOTE:-
INSPECTION OF BALL JOINTS IS IMPORTANT, ESPECIALLY THOSE IN OLDER VEHICLES.
DAMAGED SEALING BOOTS, SALT ON ROADS IN WINTER AND CLIMATIC CONDITIONS CAN
CAUSE LOSS OF THE CORROSION PROTECTION COATING APPLIED DURING MANUFACTURE.
Inspection instructions:-
Ensure that ball joint is in an easy access-position.
Carefully clean the sealing boot contact area, to ensure that pollutants cannot get under the sealing
boot during the following inspection procedure.
Use an appropriate inspection sheet-metal-tool, eg. spatula with cut out, (fig. no.5) to push up the
sealing boot (without damaging it) until ball pin surface is visible. Degrease the ball pin surface.
If there is corrosion of the ball pin or the sealing boot has deteriorated through ageing or is damaged,
replace the ball joint in question, or the complete tie rod or drag link as appropriate.
If there is corrosion of the steering lever area which is in contact with the sealing boot, clean and
eliminate all surface irregularities.
If there is no corrosion or damage to the sealing boot, smear the steering lever surface with
Lithium grease and push the sealing boot back into its properly seated position.
When dismantling tie rods, drag links or drop arms ensure that no damage is caused to the sealing
boots or ball joint housings.
