My tour de France 4x4 2014  just failed it's first MOT on rear shocks , both were leaking fluid profusely , 105 k miles , bit dissapointed with that as it's only occasionally had people or loads in the rear and hasn't been off roading

Thats not too bad considering the mileage. Our rear shocks were replaced at 50k miles as one was leaking. We are now at 96k miles and the rear springs need doing. The replacement shocks were Monroe brand (Australian).
