Less than 6 months ago I replaced the worn bottom ball joints on my Toyota Hilux. These replacements came from a reputable dealer. Yesterday the Hilux goes for an MOT and fails on bottom ball joints. Now this motor is used for the purpose it was intended but not harshly. Suspension ball joints used to last a lot longer than 6 months. Is this the result of inferior material or is it a failing in Toyota. Beginning to wish I had never parted with my Defender.
