In owners' own words
I took my 2003 tundra to a transmission repair shop, independent, to have the rear differential evaluated due to crunching sound which occurred when taking off from a stop and leaking of fluid due to corrosion on housing.
2003 Toyota tundra front end making a severe grinding, squeaking, and knocking noise. The CV axle boots are destroyed and seems like the wheel bearings and hub is going out quickly as well.

Recalls for the 2003 Toyota Tundra: 10
These vehicles had their driver or passenger frontal air bag inflators previously replaced under a prior recall using inflators of the same design. The inflators may explode due to propellant degradation occurring after long-term exposure to high absolute humidity, temperature and temperature cycling. An inflator explosion may result in sharp metal fragments striking the driver or other occupants resulting in serious injury or death.
These vehicles are equipped with certain air bag inflators assembled as part of the passenger frontal air bag modules used as original equipment or replacement equipment. In the event of a crash necessitating deployment of the passenger frontal air bag, these inflators may explode due to propellant degradation. An inflator explosion may result in sharp metal fragments striking the driver or other occupants resulting in serious injury or death.
The inflators in the front passenger air bags are susceptible to rupture in the event of a crash necessitating the deployment of the front passenger air bag. In the event of a crash necessitating deployment of the passenger's frontal air bag, the inflator could rupture with metal fragments striking the vehicle occupants potentially resulting in serious injury or death.
This is to address a safety defect in the passenger side frontal air bag inflator which may produce excessive internal pressure causing the inflator to rupture upon deployment of the air bag. In the event of a crash necessitating deployment of the passenger's frontal air bag, the inflator could rupture with metal fragments striking the vehicle occupants potentially resulting in serious injury or death.
Excessive corrosion of the rear cross member may cause the separation of the spare tire stowed under the truck bed which would present a road hazard that could cause a crash. Separation of the spare tire and diminished brake capacity could increase the risk of a crash.
These headlamps fail to conform to the requirements of federal motor vehicle safety standard no. 108, "Lamps, reflective devices, and associated equipment." These lamps do not contain the required amber side reflectors. Decreased lighting visibility may result in a vehicle crash.
Certain aj motorsport combination lamps sold as replacement lamps for use on the above listed passenger vehicles. Combination lamps not equipped with amber side reflectors fail to conform with the requirements of federal motor vehicle safety standard no. 108, lamps, reflective devices, and associated equipment. Lack of amber side reflectors in the lamps will decrease lighting visibility to other drivers and may possibly result in a vehicle crash.
Certain pro-a motors corner lamps, turn signals, and headlights sold as replacement lamps for use on certain passenger vehicles listed above. Without the amber reflectors, the vehicle will be poorly illuminated, possibly resulting in a vehicle crash without warning.
Certain pickup trucks fail to comply with the requirements of federal motor vehicle safety standard no. 225, 'child restraint anchorage systems.' these vehicles have a manual air bag on-off switch to disable the front passenger air bag and do not have a child restraint lower anchorage system in the front passenger… This standard establishes requirements for child restraint anchorage systems to ensure their proper location and strength for the effective securing of child restraints, to reduce the likelihood of the anchorage systems' failure…
On certain sport utility vehicles, due to a manufacturing issue in the front suspension lower ball joint, there is a possibility that the surface of the ball of the joint may have been scratched. The ball joint may eventually experience excessive wear and looseness, resulting in increased steering effort. The lower ball joint may separate from the knuckle causing loss of steering control and a crash could occur.
