    Hi all! I have had my prius for a year now, she is a 2004 second gen with 220,000 on her, i drove her 30,000 in the past year and i love it, but with all good things it was time for maintenance. I have a mechanic that i trust that is not a Toyota mechanic, but has always worked on my cars. I bought 4 new struts, 4 new wheel bearing hub assembly's, rear break drums and all new tires. Well, when i picked my car up after the rear bearings were done all my lights were on. They said it was due to a faulty sensor in the bearing but explained nothing else and sent me on my way. Well i traveled 500 miles this weekend for the holidays, my car now is GRINDING in the front, knocking when i turn and when i called was informed that it was because the ABS is trying to kick on singling that there is only 3 wheels working. It seems like now more is wrong with it than when i took it in. Does anyone have any input for me? i am beyond upset at this point after spending over 1000 on parts/labor and when driving now feels like NOTHING was even done. Any help at all would be so much appreciated. Im scared to even drive it now.

    welcome!
    you trust this mechanic and she won't make it right? are these oem parts? it's either a defective part, or poor installation.

    He told me to bring it back in, he said if i got another wheel bearing they would put it on for me, it started making knocking noise when i turn the wheel in the front now this morning on a short drive. My question is, would a bearing sensor make all of this happen? they said the new part had a defective sensor in the bearing but didnt explain what that meant

    I've never heard of a bearing sensor before. Maybe someone with more experience will chime in on that.

    Guessing the mechanic meant a speed sensor?

    I would be leary of driving with the reported grinding noise, do you hear this noise only when braking ?

    How many miles have you driven with this grinding noise, and has the noise changed in that time ?

    Generally knocking noises that happen when turning the wheel(s) are related to CV joints, but not always.

    Best thing might be to hold off on driving the vehicle until you can find someone that can read the codes (or possibly yourself) and report back. Your trusted mechanic (who isn't a Toyota mechanic) may not have a code reader that is compatible with your vehicle (assuming he has one at all at this point).

    I had never heard of it either, he said that it can happen with the best of bearings and that its something that is inside the bearing...so he meant bearing but id never heard of that either :( i drover 500 miles with it and it started slowly on the grinding just a little and progressively got worse on my way home, the knocking thing started today when turning at a light.. im supposed to take it back in but this is the 1st prius hes done so i wanted to know if anyone here had ever had something like this happen. I have read a lot of threads here and didnt see anyone saying this exact thing happened as a result of bearing before :/

    And no, they took off the OEM parts, none of them had ever been changed aside from the bearings and tires prior, i ordered replacements off amazon

    if he can't make it right, you will probably wind up at a dealer, and have to ask him to pay for the repairs.

    3rd gen rear bearings have a built-in speed sensor, if I recall correctly. Not sure about second gen but it might be also?

    One thing I keep reading regarding rear bearing replacement: it's difficult to disconnect the sensor prior to bearing removal, and what can happen is when the bearing comes free it goes flying, and tears the sensor cable or brakes the connector.

    Sensor is built in rear wheel bearings in Gen 2 as well.

    sounds like either the mechanic screwed up, or you bought a cheap junk Chinese counterfeit bearing and its failed already.

    My mechanic ran the codes and was able to fix it! It did not end up being that the bearing was bad at all, the system had to be re learned and just like that it poof! No more grinding, all the codes are off. The only other thing was that it needs re aligned but he fixed it and it didn't cost anything. All is fixed up! Thank you everyone for your help!

    Only thing I can think of is that the 12v battery has to be disconnected when doing the brakes to prevent any cels from coming on.

    So, about a week after i got that done, one day i backed up and all the lights popped back on. I lost my breaks going down a hill lol lucky for me the front breaks still kicked on, drove it to the shop and the spot where they apparently broke the break line and repaired had broke again. So they repaired it again, however my car even with all the new strut assembly is bouncing like a bunny in the back end. Driving me INSANE and to boot, grinding noise is back! but he said the grinding could be just the exhaust bc there was a leak which i have since got repaired too. Still grinding when i hit the breaks :I neeless to say its going back again, but what could be causing the bounce in the back? She had all 4 stuts whole Assembly replaced with shocks and all and all 4 brand new tires. Any ideas? i already took her for an alignment too. Didnt fix it like he said it would.

    Say what? You made no mention of them breaking anything before, is this the first you learnt of it?''

    Was it really the brake (hydraulic) line that they broke, or are you referring to the electrical cable for the speed sensor?

    Mechanic sounds like an idiot. Take it to the dealer for a full estimate of all your symptoms and most importantly the dealer will read the check engine lights. Make sure they list all stored codes on your receipt and post them here. They will also check your vin to see if eligible For any service campaigns and update them for free. This Is important especially if your car has not been to a Toyota dealer in years.

    This will cost $125 for an estimate. but at least you'll know what exactly is wrong.i would not go back to your mechanic.

    They broke my break line in the rear when they were replacing the drums apparently :/ My concern is im traveling 18 hours in 2 weeks and i feel like this should be not a problem. I think i will take exactly what you suggested and take her to the dealer, the nearest one is almost 2 hours from me but id hate to break down so i may as well make that drive prior to my journey than be stranded!
