2007-12 Toyota Tundra Bed Bolt Rust / Corrosion - TSB

Does your 2007-12 Toyota Tundra bed bolts look like this? If so, Toyota has released a TSB addressing this issue.

In an August 2012 Technical Service Bulletin (T-SB-0140-12), dealers were notified that the truck bed attachment bolts and washers could rust on the Toyota Tundra trucks built during this time. Toyota has produced a solution to this problem that requires the replacement of the truck bed bolts with washers.

This TSB affects all 2007-2009 TMMI and 2007-2007 TMMTX built vehicles. For the 2012 TMMTX built vehicles, only ones produced before the Production Change Effective are included.

2007-12 Toyota Tundra Truck Bed Bolt Rust  VIN List

Here is the TSB process:

Step 1: Check the following vehicle identification numbers for the 2012 TMMTX built vehicles: JU5F1, RU5F1, LU5F1, JM5F1, RM5F1, EM5F1, UM5F1, SY5F1, RY5F1, FY5F1, EY5F1, LY5F1, TY5F1, KW5F1, KY5F1, BW5F1, BY5F1, UW5F1, UY5F1, HW5F1, HY5F1, DW5F1, DY5F1, MW5F1, MY5F1, CW5F1, and CY5F1. These vehicles are both two and four-wheel drive.

Step 2: The replacement part number for the truck bed bolts with washers is 90119-A0226. You will need 6 bolts for a 5.5 ft and 6.5 ft bed, and you will need 8 bolts for an 8.1 ft bed. These truck bed bolts can only be used once. So, if they are replaced but then removed for any reason, they must be replaced again.

Step 3: Confirm that there is rust or corrosion on the truck bed bolts or washers.

Step 4: Remove and replace all truck bed bolts and washers.

This replacement is covered under the Toyota Basic Warranty for 36 months or 36,000 miles, whichever comes first, and only applies to the rusting of the truck bed bolts and washers.

Give your local Toyota dealer a call if you have a vehicle with these specifications. You can even provide them with the part number to make sure the replacement is in stock. Set up an appointment to have the replacement done.

    thanks for the heads up. Why not stainless steel is beyond me?

    Same can be said for 2007 and 2008 chrome lug nuts all rusting in the midwest due to poor chroming from mfg.
    Toyota does skimp on the little things which is really hurting their quality reputation.

    If I understand this correctly; 2007-2012 vehicles are covered but only as long as the vehicle is still under manufacturers warranty of 3yrs/36xxx miles. Hmmmm? That seems confusing since everything before 2010 is already out of warranty and ineligible for this TSB. Doesn’t matter really, I just wanted to kind of point out the oxymoron. I have had this done and it doesn’t change the crappy product toyota uses. It is now a year later than when I had my bed bolts replaced and they started rusting about 3 months ago. Toyota won’t fix it due to the 1 yr warranty on replacement parts. However, the problem lies within the coating and not the bolt. as soon as they torque the bolt down or use something metal to take the bolt out, it scratches the “armor coating” and its all down hill from there. They need to make an alternative for the people who are having this problem; like a high grade stainless hex head.
