at 75T kms, i replaced the original upper control arms with replacement parts. and now at 85T kms, the bushings and ball joint for the replacement parts are already shot! normal daily driving lang naman ako, from las pinas to makati, maganda naman ang roads, always alone or 2 persons in the car, so wala talagang extreme driving. pero 10T kms lang ang tinagal ng replacement upper control arms ko??? compared to the 75T kms na tinagal nung orig!! ano experience nyo dito!!
