Hello,
I'm a new owner of a 2003 GX470 and have a couple questions concerning the ABS pump. My ABS pump was operating fine until about a week ago when a started hearing a screeching/ grinding sound occasionally on one if not two of the booster intervals. But more recently (a couple days ago) the booster intervals have been all screeches without fail. It's not the whining sound that I have hear in other videos and only happens when the booster kicks in. I've tries flushing the system and bleeding in the correct sequence but no luck... the sound continues. Can anyone tell me what this is? Or how I can diagnose it? I like working on my own rigs but this is stumping me.
Here are a couple videos with audio of the issue.
