Wheel bearing noise

Prius front wheel bearing is theoretically easy to replace. But depending on how corroded in place the bearing is (how much salt they put on your roads etc.) old bearing can be almost impossible to remove even with a press. New wheel bearing doesn’t need press to install so they can say that you don’t need a press, but how can you remove the old one?

Only reason to do both bearing at once is that if you do alignment afterwards you don’t need to do it twice.

 

I went through this wheel bearings replacements for the same one 4 times .done by two mechanics and Toyota dealer. After all that dealer sent the knuckle to the label to check it for being bent . And it was little bid bent. I looked for replacement knuckle with wheel bearing and speed sensor on ebay 56$ very good deal. Now no more problems for over a year. Just make sure you get right one front back right or left

One more thing I meant knuckle with wheel hub assembly which most mechanics will do not (the bearing inside the hub assembly which is more work) and speed sensor.

All the ones I bought were Timken very good brand used it in Infiniti g35 2004 never failed. Then when I took it to dealer it was Toyota part and they were failing withing 3 weeks as well the whole reason was bent knuckle that was hard to see with the naked eye they had to send to the lab to find out.

The week hub will have the bearing in it, u might need something to separate something put from the hub assembly. Another thing make sure u peep the knuckle because if you let it drop it will pull the speed sensor plug and it like break it like what my mechanic did.make sure to unplug the 12 battery put your smart key far away from the car becuase it will energize the break. Just make sure you get the torque right they say if you torque the big nut more or less than the spec it will damage the wheel bearing fast . I can't remember the specs I think it was around 145lb.ft but please check. It does take like 45 mins for mechanic. And make sure to not forget the back circle steel thing.

The wheel hub my bad. Make sure you got the right socket size for the big nut with special shape

There is piece of metal need bending out before you take big nut out and bending back after putting back the big nut

I just replaced my wheel bearing in my 2015 Prius. Now the cruise control won't work and the traction control and abs lights are on. What am I missing?

 

Did you disconnect the 12V battery before you started working on the wheel bearing? If you did not, a skid control ECU diagnostic trouble code may have been logged due to vibration, removing and reinstalling the disc caliper, etc.

Clear the DTC using a jumper on pins 4 and 13 of the OBD-II connector (many posts about how to do that, make sure you have identified the right pins before you do this) or use your OBD-II code reader to clear the DTC. Then see if the problem comes back.

 

You may also want to make sure the wheel speed sensor is installed correctly and reading as it should.

 

Thank you. I am thinking you are right. It's weird, the cruise control won't work, traction control lights up and the abs lights up. Then randomly goes away and no issues.

It must be an issue with the sensor and not being attached correctly.

 

Maybe start your own thread in a Gen 3 forum, rather than tag onto an old thread in a Gen 2 forum. While they may appear to be similar, there are many differences too, and the guys over there will be better placed to give good advice on your Gen 3 problem.
