Purchasing a replacement ABS Actuator. Advice?

Sometimes you can find a part in Toyota's own remanufactured program: search for the part number with -84 tacked on the end. It's a long shot, but sometimes you hit. (I'm not finding one for this part.)

One of my concerns with a used part would just be about who removed it and how. If you read the Toyota TSBs dealing with actuator R&R, they are very insistent on preventing any kind of foreign material getting into any of the openings ever ... to the point of forbidding any cloth rags or fabric gloves (which could shed invisible fibers).

That leads to the question, what work practices were being followed by the used part seller who extracted that part from some wreck?

 

Try the Dorman and let us know the results

 

Here is a copy of a post I made to help another individual who was troubleshooting an install after using a used actuator, I wish you the best with your repair:

If you are interested in another experience. When I calibrated my actuator assy after my install it also made noises you are describing then it calibrated fine.
If you bought a used actuator this can complicate matters as you now wonder if it is another problem or the actuator.

I bought a used actuator off ebay and immediately sent it back after receiving it. It did not meet my expectations. I had studied this job and knew exactly what it involved and decided to bite the bullet and order a new one from Oalthe Toyota for $1,134 after seeing a used actuator assembly. The new uniit came with a new resister to match the supplied brake actuator.

If you replaced yours you know how complicated this job is. I would not buy any other parts or proceed until you know without a doubt you have a good actuator in place and no issues that were introduced during installation.

Your symptoms - not being able to calibrate the actuator point to the actuator as the problem. When my original failing actuation was in place I ran the calibration procedure just to familiarize myself with the procedure and see if it would clear the codes I was getting for the failing actuator. My results were what you are experiencing now.

Others have installed used actuators with some mixed results. I think installing a used actuator is a little like playing the lottery. As you are finding it introduces all sorts of unforeseen variables.. I do understand the cost considerations of a new actuator and hope your situation turns out for the best.

 

I would not buy the remanufactured unit since the cost difference between the Dorman part vs. the new Toyota part is minimal.

I would be inclined to try the used part considering the cost difference and recognizing that you might have to repeat the labor effort. Autobeyours.com specializes in Prius used parts and I have had good experiences with that vendor.

 

My local u-pull-it place had one for $30 (untested, 30 day exchange warranty). That also gave me the chance to mess with trying to remove the part without disassembling my own car. I was careful to quickly cap the line and ports to minimize dirt going in and brake fluid loss. The car felt fine once I assembled but I brought it to my local Toyota dealer to have them bleed it for $100.

Did you have to remove the inverter for access?

 

Yes I did, including the coolant tank and hose that bolts to it.
