Was making a left hand turn and heard the truck make a bang type noise. From this point on the truck started to bounce and shake. The drag link was found broken and repaired, but the bouncing and shaking continued. The truck has continued to get worse and it is damaging other parts of the truck. The shocks have been replaced, motor mounts, plastic defrost piece, doghouse aluminum piece had to replaced because of weld cracking, diamond plate flooring had to be replaced because of cracks. Now there is intermittent warning light going on but not able to find to fix.

Service brakes, air: supply: check valve
- What is wrong
- Certain freightliner school bus chassis, heavy trucks, and thomas built school buses manufactured between july 2002 and july 3, 2007, equipped with bendix sr-7 spring brake control valves. The parker scv brass 90 degree single check valves (scv) which attach to the supply port of a bendix sr-7 spring brake modulating valve can break apart. Pieces of the parker scv can become lodged inside the sr-7 spring brake modulating valve, potentially causing either leakage out of the sr-7 valve or preventing air from properly exhausting from the sr-7 valve. Also, due to a manufacturing defect in the internal rubber check valve inside the sr-7 spring brake modulating valves, the valves can become deformed and not seat properly.
- Risk
- These conditions could either result in leakage and cause a delay in the application of the spring brake without warning or possibly lead to unintended vehicle rollaway or brake drag which could result in a vehicle crash, personal injury, or death.
- Remedy
- Freightliner will notify owners and repair the vehicles free of charge. The recall began on january 11, 2008 to freightliner, sterling, and freightliner custom chassis owners; to thomas built bus owners on february 1, 2008. Owners can contact freightliner at 1‑800‑547‑0712.

Fuel system, other: delivery: fuel pump
- What is wrong
- Certain 2004 and 2005 freightliner van, motor home, shuttle bus, and school bus chassis manufactured between january 2004 and may 2005. Erratic voltage supply to the fuel lift pump causes premature wear of the pump. This premature wear could result in fuel lift pump failure and in some cases may cause an engine stall condition.
- Risk
- Should the engine stall, a vehicle crash could occur.
- Remedy
- Cummins will notify the owners of the freightliner and thomas built vehicles and will repair the engines by emc recalibration and replacement of the fuel lift pump at no charge to the customer.
