Door Lock Acutuators DIY ???
Well long story short, does anyone know a very secure way of making or making sure the original coupling stays tight on the motor shaft? I am thinking about welding the shaft and the coupling together but that seems a bit extreme.
Search "Lexus Mabuchi" on ebay to get it.
I bought the ones they said, "Small but powerful motor". Dont know if they're any different from the other ones bc there might be a few models but the one I bought is kinda noisy but it may be that its still new so its still powerful.
heres a picture of the motor.-$6
Heres what you get for $250-300....not worth it as whats not working is only the $6 motor inside this unit.

2001 GS430 Passenger side rear door actuator.
The assembly WILL come out WITHOUT removing the outside door handle.
I struggled with the damn thing for 45 minutes before it eventually popped out. You need to twist, turn, push, pull, and wiggle for it to eventually come out. Be patient, dont force it. I dont know what I did, but eventually it came out pretty easy.
Once it was out, it was easy. If you forget how things go, take a digital camera of the steps along the way so you can put it back when you are all done.
Splitting the plastic housing for the actuator motor was not too bad with a strong razor blade. Go slow. Be careful not to get dirt inside the assembly. There is nice clean grease in there.
If you are going to pry the plastic tip off the old motor shaft, put a nice long piece of masking tape on it in case it flies off. You can tape the the other end of it to something close by so you wont have to hunt for it.
We all know how nice it is to have all the actuators working. Feels like a new car!
Then used zip ties to clap the pieces back together. Just a side note to others. If you leave the door handle attached to the lock actuator make sure to test it to see if the door handle and lock move easily. Otherwise when you put everything back together it will NOT work. I found this out the hard way and this took me an extra couple hours to figure out. NOT FUN AT ALL.
Another thing to note is that make sure if you unbolt the window regulator to access the lock actuator that you FIRST put back the window regulator before giving power to the lock actuator. Found out the hard way when all the windows went down and the sunroof opened. Pain in the AS!@#$#! to get back in allignment.
For the ls series like the GS. Keep the window up. You don't need to remove the speaker. Take your time and make sure to use glue or zip ties.
Good Luck!
Check out the video online for sure. Just keep in mind that it varies for which model you have. He does a lot of unneccessary things as well.

For me I would suggest getting this motor.

It has PTC which apparently helps the motor last longer. And it worked for me after filing the round end down to fit the D shaped cap.
Good luck with your DIY. This forum has saved me mucho dinero!!!!
I am getting ready to do this and am probably gonna order 4 motors, 3 are out and 1 is going soon, so I know this is not gonna be a fun process
does anyone know the best motor to use? the reason I ask is because I thought I read that they need to be altered to fit, thanks for any help

You guys don't have to struggle with it at all. There is nothing brave about pulling on the door cable. You do that every single time you pull the door handle from the inside. Trust me it's the easiest way to get it out. 2 minutes vs 45 minutes. I'll take the former

Took it out of the door with the window up. Opened it up with a small electronics standard screw driver (used as a chisel) and a hammer while being held in place in a vise. Once the motor was out I took the toothed pinion off the motor by squeezing the motor in a vise and using a panel tool (looks like a forked standard screw driver) and leverage to easily lift it off. I hammered it onto the new motor by holding the motor in hand and tapping it on with the hammer. Put it all back together and and installed it. All done and working! Thanks again everyone.
