4.3 - Vibration problems (All)
Many Tundra owners have complained about a moderate to severe vibration problem
in their Tundras. This vibration problem ranges from steering wheel shimmy to
"martini shaker" type vibrations that are felt in the seats and the cab.
This vibration is normally felt from 35-70 MPH, and has been found in 2000 and
2001 model year Tundras, 4x2 and 4x4, TRD and non-TRD variants, with nearly any
wheel/tire combination around.
There are many causes for this vibration. If you are experiencing vibrations,
please have the following fixes performed by you or your dealer before taking
any further action such as bushing replacements, lemon law disputes, etc.
1) Verify Tire Pressures - Make sure that your tire pressure is at a range of
35PSI Cold max.
2) Verify that your tires are in balance - Toyota factory wheels are notorious
for letting the tire bead shift, thereby allowing the tire balance to become
incorrect. When your tires are balanced, make sure that your dealer or tire
outlet is using a proper tire balancer that can handle lug-centric rims.
Please see Section 3.32 and Section 4.1 for more information.
3) Verify that your brake pads, shoes, drums, and rotors are in spec and not
out of round. See Section 4.2 and Section 4.13 for more information.
4) Verify that your Drive Shaft is in alignment. Please see Section 4.16 for
more information
5) Verify that your vehicle's alignment is in specification. Listed below are
the Toyota Factory Specs for the 2000 and 2001 Model Year Tundras.
2000 Toyota Tundra Factory Specs:
Camber: .025 +/- 0.75 degrees
Caster: 1.27 +/- 0.75 degrees
Total Toe: 0.08+/- 0.20 degrees
2001 Toyota Tundra Factory Specs (?):
Camber: .025 +/- .075 degrees
Caster: 2.00 +/- 0.75 degrees
Total Toe: 0.08 +/- 0.20 degrees
If you do take your vehicle in for alignment, make sure that the alignment
specs are as close to the following numbers as possible:
Camber: 0.23/0.27 degrees
Caster: 1.93/2.03 degrees
Total Toe: 0.09 degrees
These fixes have been tested by many members of the Tundrasolutions web page,
the FAQ author included. The fixes has corrected about 95% of the vibration
problems felt or reported by Tundrasolutions members.
