I own a 2006 Highlander Hybrid and need to replace the brake actuator. I am weary about replacing with a used one because the originals were failing prematurely. I also would rather not put a brand new one into a 15 year old vehicle with 235,000 miles on it. I am assuming the new actuators have a design change that fixes whatever issue the originals had that made them fail prematurely. Is there anyway to tell if the used ones incorporate the new design or do I have to buy a new one to be sure??

 

The updated unit is 44050-48191 if you see 44050-48190 I would assume that is not the updated part. There may have been a running change, but 44050-48191 will definitely be the revised actuator. My memory if fuzzy, think there was a warranty extension where Toyota would replace defective units but there was never a recall.

Every single used part is going to be 44050-48190 because the only way you'll see the revised part as used is if the donor car had the repair done, which wasn't very many.

td;dr don't think there is any way to know if 44050-48190 is an updated version if that happened at all.

 

04003-45148 is OK since it was installed as a warranty replacement (# from tsb)
44050-48191 is OK since it was installed as a non-warranty replacement (when the warranty has expired)

 

Thanks!!! LeX2K and iMSQ...

 

Why are two different part numbers still available?

 

dealer could order the first one for warranty replacement only...

 

Both Parts available here https://parts.elmhursttoyota.com/ Seems to be run by a 3rd party site called revolutionparts as several dealers in different sates have similar site. About to pull the trigger for one of them and see if i can do local pickup. Time of writing both part cost $1,177.33.

 

So is it safe to use the new model?
