Condition

Some customers may comment on a rattle-type noise that sounds like it is coming from the back of the cab in the driveline area. This condition mainly occurs when the vehicle is under load on a slight grade. The sound may be more prevalent as the vehicle warms up.

The condition can be duplicated in 3rd or 4th gear at about 1800-2300 rpm and may be mistaken for a transmission concern. The condition will only occur on 2-wheel drive vehicles equipped with a manual transmission.

Cause

The condition may be caused by a clutch damper high friction, allowing engine power pulses to resonate in the transmission and driveshaft, resulting in a rattle.
