Signs of AWD or 4WD Failure

For most vehicles today, especially trucks or larger SUVs, the AWD and 4WD is a major selling point and part of the reason to buy these vehicles. If the off-road capabilities stop working, that can be a major problem not only for weekend warriors but also for everyday driving. If you see some of the following signs in your vehicles, it may be worth deciding if you want to keep the vehicle and repair it or if it may make sense to sell your vehicle.

Warning Lights or Messages

You might see:

• AWD/4WD warning light
• “Service 4WD”
• “AWD Fault”
• “4WD Unavailable”
• “4WD Overheated”
• “Check AWD”
• A flashing 4HI/4LO indicator
• ABS, traction-control, or stability-control lights appearing at the same time

A warning light by itself doesn't prove mechanical failure. AWD systems rely heavily on ABS/wheel-speed sensors and electronic control modules, so an electrical or sensor problem can disable AWD.

Especially suspicious: AWD/4WD suddenly stops working while the vehicle otherwise drives normally.

Clunking, Banging, or Grinding

A clunk when accelerating or letting off the throttle can point toward:

• Worn driveshaft components
• Universal joints
• CV joints
• Differential problems
• Transfer-case problems
• Excessive drivetrain play

A grinding or growling noise that increases with vehicle speed can be more concerning for a differential, wheel bearing, transfer case, or other drivetrain component.

If you hear a loud metallic grinding, avoid continuing to drive it until it's inspected.

When To Stop Driving It

I'd be much more cautious if you have the following issues because they could lead to more costly repairs and further damage additional components of the vehicle.

• Loud grinding
• Repeated banging/clunking
• Severe vibration
• A significant fluid leak
• Burning smell/smoke
• 4WD stuck in a mode
• Sudden loss of drivetrain power
• A wheel/axle that appears mechanically damaged

Those can indicate a mechanical failure that could worsen or potentially leave you stranded.
