A selenoid is activated from the rotary switch on the dash. This selenoid engages the AWD system causing the slight clunk
When you turn the wheel, or while you drive?
A bad gear can cause your four-wheel-drive transfer case to make a clunking sound. The transfer case should be checked immediately.
Wheel bearings or u joints
Depends on which part of the truck the noise is coming from. Could be an u-joint, a wheel bearing, a failed transfer case......
Check the CV joints. (front wheel & 4 wheel drive vehicles)
Drive shaft play/possible worn/bad ujoints /driveshaft
soounds like steering wheel fluid needs to up
it would be the CB joint it it's a front wheel drive vehicle with high mileage.
If you operate a front wheel drive vehicle, the clunking noise you hear may be a CV joint bearing going bad.
On a front wheel drive car I would suspect bad CV joints. On a rear wheel drive car I would suspect a bad universal joint. Have a mechanic look at it right away.
The 2002 Ford Escape has front wheel drive.
The 2008 Ford Escape has front wheel drive.
