Alloy on the truck

I have an 07 TRD sport LB 4x4 with 17" wheels. Does anyone know if there is any other alloy on the truck. Basically, is there any metal that on the truck that is the same as the alloy wheels?

 

uhh, the engine block is aluminum like the wheels.......

 

I think the tranny is aluminum too an probably the cases on 4x4

 

oh, the wimpy factory "crush bar" inside the bumper is aluminum too, and the radiators for that matter.....

 

Wonder why the question though Kj?

 

Well my wheels are bubbling and the Toyota rep said it is not coverd by warranty because it is happening to all 4. If it were one then they can call it a defect. Since all of them have the problem it must be an outside source (aka chemicals or something used on the truck). So I asked him if that is the case then the other alloy on the truck should be affected in the same way, correct? Is it the same type of alloy used on the block, t-case ect... the same as the wheels?

 

The bubbling you see is between the finish and the bare metal. The t-case, engine block, crush zones are not coated in the same matter, not to mention they do not see the same harsh elements as the rims.
Continue searching this forum as well as some of the other Taco boards, for thsi problem, as it is becoming more and more numerous. If enough people come forward, Toyota will have to address.
