    My recently bought 2009 Base model with 146k is making the classic symptoms of the failing actuator. Making noise every few seconds. The car came with a used unit in the trunk with part number 44510-47050. Seems the previous owner was planning to replace it. It does not look good and have rust in some areas. My questions are

    1. Part number listed on Toyota website is 44500-47141. But the website photos shows 44510-47051. Read that this is the actual part number. ?
    2. 44510-47051 - does it have failures like the 44510-47050 version? Or it will also fail within couple of years? 44510-47051 - i can get one <$600 in ebay. Seems to be good units. If this one also have failures, i would prefer to go with new one.
    3. Online/ebay router - they sell without the resistor - Can i re-use the existing or will it create problems?
    4. Lastly, does the failing actuator affects mpg? It stops the regen braking? I am getting 33 now.

    Please see below. Brakes works fine so far and no codes. It is highly irritating.

    No you should be able to buy good units off eBay from very reliable large sellers namely the junk yards down in Conyers Georgia look at the sellers business page or whatever those guys are showing these things for around $300 $350 no matter how they look don't let that fool you I install used ones a few times so far and a couple of them have looked like trash. And are still working like gangbusters I've only had to change one twice because the replacement from the junkyard was bad getting put in my hands oh well. I'm not sure all the numbers and whatever you want to find the latest one you'll be surprised how many cars you find with brand new actuators in them sitting in the tow lots because the battery went bad a month or two after they did the actuator and they flat out that made up their mind they're not spending another thousand plus dollar repair on this old piece of you know what and off it goes and they go get a payment or whatever they do You would be shocked matter of fact many of them have the receipt in the glove box because that's how Prius owners are they might have to call for warranty or something and have their ducks in a row generally speaking well the original Prius owners anyway.

    Did you used 44510-47051 or 44510-47050 ? I live in Dallas, TX. Local junk yards, didn't find many with good units. Online i found one with $415 for 44510-47051.

    Used units, what i read is, 44510-47051 is revised unit. But cant find any concrete information on it fixed the issues from 44510-47050. The used unit i found in the car is the older model and that's why i was reluctant to try it. I guess it is worth a try first.

    Wonder what kills it. Design.Manufacturing defect or not changing the fluid on time.

    Found 2 on ebay with 44510-47051 (updated part number) . <$500. For some reason it is not allowing me to post links. item numbers 276537391229 and 266859822180.
