    Have changed recently on my 08 Prius hatchback base. Lots of front end parts including - rotors, calipers, left front hub assembly, struts, sway bark links, pads. Blead in sequence. Now have vibrations. Only when turning left. Worried about the ecvt for most. Although have done research. Now and also changed tires to winter could be bad tire. Or possibly. Right tire front hub assembly. Or cv joint. Really hoping it's not the evct cause I missed the inverter pump and damaged the synergy drive. Again only left and I just changed left wheel hub assembly. Checked right seems ok no 12 I clock to 6 o clock. Some 3 to 9 but honestly spun wheel in neutral sounds fine.. any thought as to bas tranny are appreciated. I also think maybe a wheel sensor might be bad another issue at same time throwing a trouble shoot issue into the mix.

    I doubt it's your transmission you don't say where you are what part of the country you're in or any of that just for weather road quality rust and all that so nobody can really know squat. Unless you're some kind of unique driver I doubt you damaged your transmission unless you spend every minute in the car trying to be Mario and ready or something similar so more than likely all of the parts you have replaced have come up to the sum of a vibration one wheel bearing and not the other and so on and so forth is a recipe for having things like this creep up but hey you're saving a couple of bucks by not changing one or two items so you know kind of par for the course you'll get it you'll figure it out or your front end guy will one of the two sometimes front end problems can be tricky at home in the driveway now they have microphones they strap on to the front end of the car and all kinds of stuff they do drive it down the road and can listen right there at the hub assembly and so on and so forth realizing this stuff is generally not at the home mechanic shop so maybe some more expertise is needed I've changed all those parts on four or five of these Prius sitting here at my house and have never had any of these problems and I generally won't be looking at the transmission too often.

    I'm
    Yeah, I think I've hit the point- time for some harness and sensor diagnostics. I know will be cheaper to bring to my guys, than just process of elimination and doing reasearc, buying and swapping parts. Regardless, my Prius has over 200,000 so engineering wise time to replace and maintain a lot of stuff. Hoping to get to 300k+ thinking the old girl "prea" the Prius has it in her. She's definitely getting some well needed TLC. Thanks again for reply. I'm really hoping and doubt is the transmission bearings or electric motors in there, maybe a gear issue abnormal wear or bad tolerances. Just hoping I didn't overheat with the inverter pump being bad or neglect a other issue causing to have damage. Their solid cars and engineered very well. Why I bought my little prea at 170k. I'm second owner and use for same purpose as original owner, for delveries. I usually take it easy on the old girl, It's my first hybrid, therefore still learning a lot. Will keep posted scan findings and where vibration is coming from. At least I can go in and say what I know it's not lol...
