HI, I am still holding out on replacing these bolts and now more confused than before. I bought the bolts # 14126 and was told that was the proper bolt to use and that it was not an issue with a defective bolt but more with improper drainage causing rust. Then I read the above post. So, now there is a different part number, does anyone know if it is actually a new and improved bolt? Thanks. I just want to do this once and hopefully get it right.

Toyota often seems to change part numbers, and sometimes with no visible change to the part (it could be something as simple as them changing suppliers for the part and hence revving the part number). I bought some of the 90119-14151 bolts and there does not appear to be any difference in strength rating, plating, etc. with the new part number.

I personally plan on checking (and perhaps replacing) the bolts once per year.

i just got to replacing the bolts for the new and improved. there is some difference in the stamping, probably improved strength, but don't know how to decode it (see picture).

i did remove the old ones a couple of years ago to inspect, grease, and retorque. there was some superficial rust, but it didn't get any worse after nice greasing the whole length. in retrospect, i didn't need to replace it.

but, the car never saw any snow or ice. it would be very different in the salted roads states.
