The solution to these problems is the limited slip differential (LSD), sometimes called positraction. Four-wheel drive systems found on trucks and SUVs typically have a transfer case instead of a center differential. Limited Slip Differential problem. In this guide, we’ll dig a little deeper into the mechanics of differentials and break down everything you need to know about different limited slip differential types. Unlike high-tech electronic lockers, the G80 differential detects wheel slip through some flyweight-type governor. Step 1 Troubleshoot the limited slip rear axle when experiencing a shudder or bind from the automobile's rear axle during low speed turns.
