Ball joint boots replaced




Tie rod ball joint boots in frontal axle of XH200 B-Vectra were replaced this morning in the condition of 37 degree celsius temperature. As the locking nuts of the joints were distorted intentionally to have some slipping resister, special tool, air impact device and a rare size socket 18mm. Without impacting action just with hand tool, loosening procedure might be possible if the knuckle and joint parts are fixed well, tightening procedure requires hitting action tool because slipping resistor is too strong to prevent the rotating action in the ball joint case, however hard we might try with hand tool, ball joint part rotates together with locking nut. A plastic color was found inside of the joint boot on both sides, but I don't understand that how this part plays actually, so I removed it and applied Chrome Molybdenum grease fulfilling inside. Metallic wire circle clip was set on the small end of the boots that causes unnecessary twisting distortion when steering was turned. As a personal opinion, the cir-clip on the small end of the boots is not the parts to be set there, because the small end and joint part should be slipped well when necessary, otherwise the rubber boots is twisted inconveniently leading to the fracture like this time. Exactly the same thing is said on the rear lateral arm outer end ball joint parts for both upper arm and lower one. The moving parts which require rotating movement should be slipped well without any stress like twisting phenomena. Ball joint parts are very important to keep the accurate smooth action and have some character to be worn very easily if any harmful muddy dust might invade in them.
