Year of Manufacture: 2009 ( Optional ) Engine Code or CC: 2.5
Kia sorento with loud banging noise from gearbox area at around 40-50mph,mainly in 4th or 5th gear. Bad enough to hold back vehicle briefly. At lower speeds and gears its possible to drive without issue, but under load it returns at around 50mph. Cant find anything obvious in the prop shafts etc although there is quite a bit of backlash in rear diff. It has had a used front diff fitted at another garage as old one blew up although that all looks ok.I Cant pin down the source of the noise it could be the gearbox or transfer box area.Theres a fault code in the 4wd ecu which is P1739 General position encoder fault.
