The invention discloses a wear-resistant front ball head balance pull rod on an automobile. The balance pull rod comprises a pull rod, cylindrical ball head seats are formed at the two ends of the pull rod, ball head pins are arranged on the ball head seats, round sinking tables are formed on the upper end surfaces of the ball head seats, inserting holes are formed in the middles of the bottom surfaces of the sinking tables, and round counter bores are formed in the lower end surfaces of the ball head seats. A conical front limiting hole is formed in the bottom surfaces of the counter bores and communicated withthe insertion hole. The ball head pin comprises a spherical steering head, the steering head is inserted into the counter bore of the ball head seat and abuts against the inner wall of the front limiting hole, a connecting column is formed on the steering head, the connecting column penetrates through the inserting hole of the ball head seat to form a round limiting check block, and a stud is formed on the upper end surface of the limiting stop block. Lubricating grease is arranged between the pull rod and the steering head of the ball pin, and a good sealing structure is arranged between the pull rod and the steering head; and the abrasion between the two can be effectively reduced.
