4×4 / AWD — FAQs
Can the wrong fluid damage my AWD?
Yes. Many AWD clutches require specific fluids or additives. We follow OEM specs to prevent chatter and clutch wear.
Why does it bind in tight turns?
Old or incorrect fluid, stuck clutch packs, or actuator issues can cause binding. Service and calibration typically fix it.
What’s “pump rub” in a transfer case?
Certain cases can wear a hole in the housing over time, causing leaks and failure. We install updated parts and reseal to prevent it.
Do you calibrate or reprogram modules?
Yes — after certain repairs we perform learn procedures or module programming and verify engagement on a road test.
