4WD Noise

Recommended Posts

I noticed the other day when I switched into 4WD Hi some noise coming from the ball joint/front tire area when turning at 90 Degree from a stop sign. Is this normal? I assume this is somewhat normal as the tires can not slip to turn at different speeds? I do not use the 4WD on dry roads, but thought I would just make sure it would work when needed.

 

Thoughts?

bcridez,

 

What model year truck are you driving? If you're still within your new vehicle warranties, it would be a good idea to get the truck in to the dealership to get this looked into. Let us know if there's anything we can help with (setting up an appointment, locating a dealership, etc).

Normal. When you have it in 4 high or low, the transfer case splits power front to rear 50/50. This is ideal in poor conditions to ensure you don't lose all power to one wheel without traction but in day to day driving all four wheels turn at slightly different speeds when cornering. The transfer case doesn't allow for this so you get tire scrub and driveline windup that can create the noises you hear. You'll also get some drag I'm the steering.

Any of the folks on the forum from Atlanta, Ga area? I am looking for somewhere to test the truck off-road a bit. Nothing too intense, just some light trails or power lines. Preferably no mud...I would hate to muddy the underside of a truck with only 1800 mi.

Use of 4HI or 4LO and 4HI Lock or 4LO Lock on Full-time 4WD is intended for use on a low traction surface such as snow, ice, mud or sand. On a high traction surface, the higher traction levels will create more binding and noise in the driveline.
