Chevrolet Repair Questions? Ask a Chevy Mechanic for Answers ASAP
I am sorry for the long wait
only in 4WD it will do this ?
do you hear the noise under the truck or from the front of the truck ?
if you run this up in the air in 4WD can you hear the noise from the front axle itself ?
anytime there is this type of noise it is not a sensor
can i ask when in 4WD the 4WD works and powers the front wheels but it just makes noise ?
i am sorry for all the questions but i want to be sure to give you the correct answer
sometimes we have to ask a few questions to be sure on your problem
if you hear this noise only in 4WD and it is from the front axle itself the issue will be the ring and pinion or possibly the front axle not fully locking into place which would make the same type of noise
that is why i asked if the 4WD will work correctly or not as it matters if it does or not
ok that is fine
what you need to do is remove the drive shaft from the transfer case to the front axle if the noise goes away the noise is from the transfercase internally
if the noise is still there with the shaft out the problem will be the ring and pinion in the front axle OR the front axle is not fully locking in which is usually caused by a broken inner passenger side axle tip or the washer behind the inner axle shaft broken causing the front actuator not to be able to fully lock into 4WD as that point i would pull out the front axle actuator and see if you can fully lock the front axle by hand then the issue will be the ring and pinion or the side bearings or the pinion bearings which for any of those repairs the front axle needs to come out to be repaired
we do not know the customers skill level
i am real sorry you are disappointed but with this noise being a few things that can cause it we have to ask a few questions on the issue as we have seen so many things cause this noise and we want to be sure to narrow the issue down to the problem area without guessing
it is not cut and dry of a 100 % common oh its this or its that
