It\u2019s not unusual for automatic transmission or gearbox specialists to also work on differentials<\/strong>, as the components perform a similar task:<\/p>\n The differential<\/strong> sits between the wheels, where the drive shaft connects with the axle. Depending on whether your vehicle is front-wheel drive, rear-wheel drive or four-wheel drive, the differential<\/strong> is on the front, rear or both axles.<\/p>\n In addition to differentials<\/strong>, four-wheel drive cars have a transfer case<\/strong>. The transfer case<\/strong> acts like a differential<\/strong>, but channels power to the two differentials<\/strong> on different axles rather than to two wheels on the same axle.<\/p>\n As in a gearbox, a differential<\/strong> and transfer case<\/strong> require fluid to lubricate the gears, shafts and bearings where metal slides over metal. The oil also transmits heat away from the working surfaces. However, as time goes by, the fluid tends to become dirty or can even be contaminated by water, losing its ability to do its job effectively.[\/vc_column_text][\/vc_column][vc_column width=”1\/3″][vc_single_image image=”146″ img_size=”full” alignment=”center” onclick=”custom_link” link=”http:\/\/www.aautomotive.co.nz\/company\/#1496124582239-df3fd6b0-dd16″][vc_single_image image=”60″ img_size=”full” alignment=”center” onclick=”custom_link” link=”http:\/\/www.aautomotive.co.nz\/company\/#warranty” css=”.vc_custom_1494586487131{margin-top: -20px !important;}”][vc_single_image image=”138″ img_size=”full” alignment=”center” onclick=”custom_link” link=”http:\/\/www.aautomotive.co.nz\/company\/#1494567324029-faffc764-88571496124438939″ css=”.vc_custom_1496125572632{margin-top: -20px !important;}”][\/vc_column][\/vc_row][vc_row][vc_column][vc_column_text]A\u00a0differential<\/strong>\u00a0or\u00a0transfer case<\/strong>\u00a0seldom give cause for concern in most modern cars, as long as they\u2019re serviced regularly. Servicing requires only a small fraction of the cost of rebuilding or replacing a\u00a0differential<\/strong>.[\/vc_column_text][vc_column_text]What the service includes:<\/strong><\/p>\n While a differential<\/strong> or transfer case<\/strong> is a relatively straightforward mechanical device, it\u2019s worth making sure that nothing goes wrong with them.<\/p>\n Contact<\/a> A Automotive Services today to get a quote<\/a> to have your differential<\/strong> or transfer case<\/strong> serviced by an expert.[\/vc_column_text][\/vc_column][\/vc_row][vc_row][vc_column][vc_column_text]<\/p>\n Your differential<\/strong> or transfer case<\/strong> needs to operate efficiently to transfer the torque coming out of the transmission to the wheels. Differential faults<\/strong> or transfer case problems<\/strong> will see your vehicle operate at reduced power or not at all.<\/p>\n The differential<\/strong> sits on the drive axle and regulates the power to the two wheels on that axle. On a standard rear-wheel drive car, for instance, the outer wheel has to travel a slightly longer distance when you turn and therefore needs more power.<\/p>\n A four-wheel drive vehicle also needs a transfer case<\/strong> in addition to differentials<\/strong> on both axles. A transfer case<\/strong> does a similar job as a differential<\/strong>. It splits the torque between the front and rear axles. Some transfer cases<\/strong> operate part-time to allow more economic two-wheel driving when four-wheel drive isn\u2019t needed, while others are engaged full-time. Some of the latest transfer cases<\/strong> can automatically shift from two-wheel to four-wheel drive, depending on driving conditions. Transfer cases<\/strong> can be gear driven (mostly for larger or hard-working vehicles) or chain driven (popular for lighter and recreational vehicles).<\/p>\n The most obvious early signs of trouble with a differential or transfer case are knocking or clunking sounds, rumbles or oil leaks.<\/p>\n Diagnosing what\u2019s wrong always comes first. Sometimes this can be done without any major dismantling. When we do have to take apart the differential<\/strong> or transfer case<\/strong>, we strip it right down and inspect each part for damage. Any unserviceable components are replaced with new or reconditioned parts. Those that pass our tests are cleaned and returned to the assembly.<\/p>\n Depending on the extent of the fault in your differential<\/strong> or transfer case<\/strong>, it may be more cost-effective for you to exchange the entire unit rather than repair or rebuild your original. Our technicians will advise you if you need an exchange differential or transfer case once we\u2019ve determined how serious the problem is.<\/p>\n Whether we repair or rebuild, we always test your differential<\/strong> or transfer case<\/strong> to ensure it works perfectly.<\/p>\n To get your differential or transfer case<\/strong> repaired or rebuilt by the experts, contact<\/a> A\u00a0Automotive Services today to get a quote.<\/a>[\/vc_column_text][\/vc_column][\/vc_row][vc_row full_width=”stretch_row” content_placement=”middle” css=”.vc_custom_1494563734291{margin-top: -35px !important;background-color: #ee2225 !important;}”][vc_column]\n
