  Dt: the consumer has a 2004 volvo 670 tractor. Was having a problem with the air rod that held up air bags for the air bag system, suspension, the rod slipped and fell, causing the airbags drop. When the airbags dropped with a trailer on the truck it caused all the weight of the trailer to be concentrated on the rear of the truck due to the airbags dropping and letting the rear of truck lower. Vehicle was taken to the dealer, who told the consumer that the rod wore out. This was the sixth time that repairs had to be done. also, dealer also told consumer that if he did not stop and fix the rod when driving it will ruin the transmission. dealer stated that the original rod was too short and this caused the rod to pop out. Mechanic at dealer stated that he had a lot of this problem in these trucks. *Ak

  The self canceling turn signals don't function safely during turning maneuvers. *nm stationary splash guard mounted over the steering tires blocked safe access to the outer windshield and prohibited windshield cleaning. it took 95 pounds of force to press the clutch pedal. the gearshift stick was mounted too far to the right and to far too the rear, relative to the location of the driver's seat. the driver's seat IS mounted too far forward. the right front power rearview mirrors were not mounted securely in their housings and as a result they vibrate. the high beam indicator light IS located at the bottom edge of the instrument panel. with the tilt steering column the light was hidden behind the hub of the steering wheel. the door steps are higher and farther apart which strains the driver's knees and makes entry and ext from the cab more difficult.
