How is your replacement holding up? How difficult was it to replace yourself?

After really eye-balling the one I had in my car and this one on eBay, I didn't see any difference in the two by eye so I took the chance. Keep in mind, the 44050-30670 was over 2K........Long story short, dropped in the new one yesterday and rolling like new. Hope this helps someone because this was TRULY a headache for me!

Have you checked the master cylinder, I thought mine was the same issue but replaced the mc and have not had any problems since.

How do I check the master cylinder, what was your experience with replacing it and finding the part?

My part is doing great. I took it to a local mechanic who has experience with ABS pumps.

I found I was getting the buzzing sound off and on while driving and for a minute or two after turning the car off. I would also get what sounded to me like a seal barking. This started off about a month or two ago, it wasn't super loud, but it was starting to happen more and more frequently. I took it to the dealership and they said it was my brake actuator assembly going out. ~$3650!

I don't have any warning lights on right now, but they said that the sound would get more frequent and eventually the ABS would go out completely. Crap. From what I have found, the brakes will still work, but the ABS will not activate. OR possibly the brakes could lock up completely.

Either way I would like to get this fixed. I want to give this car to my little sister in a few years, so I would like for it to be in good shape.

Well I looked online and found a used one for $850 and a shop around here that will do the repair for $3-400. I am going to take the car in next week to the local shop to get their professional opinion. If they give the same pronouncement, I'll go ahead and get the part and have it installed the week after.

I was wondering the same thing about the pumps online especially since some come with warranty. I bought my gs460 3 weeks ago and realized it was doing that after a few days. Car came with a two month warranty and luckily it covered the new part so I was relieved!

From what I understand it is different than the gs350/300. I know the 300 is hydraulic not electrical like the 430/460
