Lexus dealer replaced " ABS actuator" and I remembered of this 2016 TSIB L-SB-0016-16 that in the original thread referred to part "04003-45450" being the latest replacement for this vehicle.

Just double-checking because the part they installed is listed as part # "44050-50170" does not match the ones on the 2016 TSIB part "04003-45450"?

Now, I found this part # "44050-50170" listed under this TSIB from 2019

So my question is what has been done under part # "44050-50170" and which TSIB is the proper to follow, 2016 or 2019?

BTW- as a result, of this repair, while the squeaking/hissing noise is gone - but - knocking noise at low speed (aka in traffic) is still there....

 

44050-50170 seems to be the latest part number. Also 04003-45450 is not traceable through parts.lexus.com. However, there is one available on Ebay.

 

Appreciate the insights, was confused about what exactly has been done by lexus, for this repair listed as "ABS activator" or"Assembly" only? or both? Seems the 2019 TSIB supercede the 2016 mentioned in the original thread on this topic - thanks again!

 

Adding link to the ebay 04003-45450 as reference, just in case someone is looking for it:

 

This again duh lol. Disregard the sticker on the unit (it's a part no for electronics box of it only and it's not order-able separately). You can't id the unit proply without it's factory box+sticker...

 

Make sure you save the TSBs and LSBs permanently to share later on. Toyota finds them and deletes them online so we cant find them.
