2003 Toyota Tacoma ProblemsLoud Rattling or Slapping Noise from Engine
Loud rattling or loud slapping may be heard from the engine on the 1995-2004 Toyota Tacoma with the 2.7L I4 engine.
These noises has two known causes: a failed balance shaft bearing, and a failed timing chain tensioner.
The balance shaft, also known as the counter rotating assembly, is installed to reduce engine vibration, and counter the rotational force of the crankshaft and camshafts. When the bearing fails, it will rattle loudly, and the timing chain will produce a metallic slapping noise. The rattle has been described as shaking a can of marbles.
The timing chain tensioner is also known to fail, allowing the timing chain to contact the timing chain housing. This produces a metallic slapping noise coming from the front of the engine, but there is no "can of marbles" sound associated. This would not indicate balance shaft failure, but the timing chain may need to be replaced.
To repair these issues inspection of the entire timing chain system will be necessary, and replacement of the timing chain, timing chain guides, balance shafts, timing chain tensioner, and associated seals may be necessary.
Avoiding these issues may be possible by early oil changes, and using the factory specified engine oil.
I got rid of my 2009 Taco because of noise during nonacceleration around 70 mph. I'll be darned if the 2011 doesn't do it also! Come to find out that it is a known problem that they didn't tell me about until I had traded vehicles. It is a serious rattle during times of slack accelerator pedal at higher speeds.
Toyota issued a recall on the lower ball joint due to the possibility of premature wear from improper finishing in production. The ball joints will be replaced under the recall. This recall applies to 2001-2004 models only. Please contact you local Toyota dealer to see if your vehicle is included.

2003 Toyota Tacoma RecallsThe Spare Tire Carrier May Rust and Break
Vehicles currently registered, or first sold in states where salt is used to de-ice the roads, are being recalled because a metal plate which helps secure the spare tire may rust excessively and break. This rust condition is a result of an insufficient coating of anti-corrosion material during the manufacturing process. If the plate were to break, the spare tire would come loose and fall from the vehicle while driving. Toyota is currently developing a remedy for this recall and will notify owners of affected vehicles when the remedy is in place. This is expected during December of 2012.
Toyota has recalled 2001-2004 Tacoma, 2002-2004 Tundra and Sequoia, and 2001-2002 4Runner models because the surface of the lower ball joints may have been scratched during assembly, which may have compromised their integrity. The ball joints may loosen and fall out and the driver may experience a loss of steering control. Dealers will replace the front suspension lower ball joints.
