\n<\/strong>The four-wheel drive configuration uses a dual-range torque divider (PTU) and a dual-range rear-wheel drive module (RDM). The dual-range offers four-wheel drive high and four-wheel drive low. Both the PTU and RDM must be in the same condition to avoid binding conditions. Some applications use an RDM with the differential lock.<\/p>\n
\n<\/strong>The all-wheel drive configuration employs the single-range torque divider (PTU) to provide a power flow equally divided between the front and rear. The system also utilises a single-range rear differential in a component called the rear drive module (RDM).<\/p>\n![\"\"](\"http:\/\/www.checkstar-techblog.it\/wp-content\/uploads\/2017\/07\/Immagine1.png\")
