Today was a busy day for mobile car batteries perth wa and mobile mechanics!  both with calls for roadside assistance , mobile car repairs and car servicing ,Even the  CMM Automotive service centre with larger car repairs and also car /truck servicing was flat out ! but we had a Holden come in to the workshop with a driveline noise that had been getting worse and worse so the owner thought they might get it looked at and have a car service at the same time so we went through and did the usual vehicle inspection and found when we checked the rear diff oil we found lots of metal in the oil from warn diff bearings !!! This is usually caused from poor car servicing [he should have come to mobile car batteries perth wa]
