2. What does remanufacture "Driveline Product" mean?

  • A remanufacturing Driveline Product (i.e Gearbox, Transfer Box or Axle) is a product that has been completely restored OEM specifications, utilising quality components sourced from OEM approved manufacturers, with the equivalent of a new product warranty. Throughout the remanufacturing, the fitment process and during the warranty period, stringent standards and procedures are observed in terms of the SABS ISO 9002/SABS0279 and AA Quality certification. The end result is therefore a product with the reliability of a new product and the same level of protection for the end user. On the other hand a Refurbished/Reconditioned Driveline Unit is a product that has been repaired and brought back to running condition without particular standards being observed.
