| Description of the problem | I went to rotate the tires for the first time on my 2010 rav4 2. 5 v6. I had never had the tires off before. The only time they would have been off was when i went back to the dealer after having the car for approximately 6 months to have the front 2 wheels re-balanced because of a slight shaking in the steering wheel. This fixed the problem. However when i went to rotate 4 tires, 2 of the front lug bolts broke. When i inspected them i could see that a couple more looked like they were also stretched between the threads, most likely from over torquing. Knowing that they would likely break also, i decided to reinstall the wheel anyway and see at what torque point the others would break. The ones that already were stretched broke at 85 ft lbs. 2 others that were not visibly stretched broke at 90 & 95 ft. Lbs. I've worked on and restored cars for 50 years. I know what wheel studs will take before they break. I've never had 13 mm or 1/2 inch wheel bolts break at this low torque. The replacement bolts, wagner brake brand, are marked as a metric 10. 9 strength bolt, equivalent to a sae grade 8. These are rated to take +/- 100 ft. Lbs. Torque. The stock toyota bolts have no markings and they recommend 80 ft lbs as the amount to tighten to. I believe 8. 8 are stock strength bolts which would take 80 ft lbs, but these are inferior if they are 8. 8 and leave no margin for error (over 80 ft lbs). Someone using an impact wrench could easily over stress these inferior bolts. I have saved all 20 bolts i replaced. I believe if they were independently tested it would show that they are unsafe for these cars. From what i have found on the internet, this seems to be wide spread on most 2009 and 2010 rav4 cars. It would be interesting to see what these 2 years bolts test at compared to the 2012 and later models. It might show that toyota knew they had a breakage problem. |
