Ford 4x4, Driveline Clunking
have a '96 Ford truck4x4 extended cab. When stopping at lights the driveline
or transmission makes a clunk sound. Is there a recall or a fix for that?
be sure that your universal joints in the driveshaft are in good condition.
If they are, there is a bushing at the end of the transmission (transfer
case on four-wheel-drive vehicles) that supports the front of the driveshaft.
It is not uncommon for this bushing to wear and when this bushing becomes
worn, a driveline clunk and/or vibration can occur. The bushing is not
costly and is easily serviced.
