Throttle actuator rebuild. And it worked!

Hopefully this will be useful to some people on here. I recently had a throttle actuator go bad which was replaced 30k miles ago with a used one. I’ve had no luck rebuilding them with the cheap 30 dollar gears on Amazon, so I was reluctant to do it again. Being the type of person that I am, I figured I’d risk failing it anyway and give it another go.

I purchased the following gear set from Amazon with free overnight shipping.

Installation absolutely sucks when rebuilding these, but it’s well worth it. The clearance is as tight or tighter than stock. So tight that I had to use lithium grease to make sure they’d move completely. After everything was back together, I started the car error free. There’s a review which shows that someone else had them last for 30k and they’re still running strong.

If your throttle actuators are dead, use these!

New gears fix the problem if your original gears are bad and the circuit board is good. They obviously don’t help if the circuit board is bad. Often when TA fail, the circuit board is bad.

Yes I ran into this. The light ended up coming back on. Thankfully I have a known working one. I’m going to swap the board since the gears are already in. No point in putting one in that’s going to fail again.

Sorry, did it work or not? I got confused.

Can’t speak for the OP, I now have one I bought new a few years ago and one rebuilt one from MPower a couple of years ago. I previously changed gears in 4 actuators without any lasting success. I recommend new or rebuilt, but not new gears.
