Prius 3 pulls left while driving and breaking/rear axle/suspension issues

Hi guys
I have problem with my prius3, steering wheel is pulling left on flat road, and even more when road is on angel, in the same time if opposite road angle, steering wheel stays almost straight, also when breaking, steering wheel is going left, I bought 4 new tires, i swap tires left to right, front to back, no difference, still pulls, done alignment in 3 different shops, last with 3d geometry, they leveled steering wheel and front looks perfect, but we found that back alignment is not great( check pic), but cant be calibrated in prius 3... I also had some knock when turning left from stand still, but it fix it self after putting new tires, I went to mechanic to check suspension, we found that front suspension wishbone bushing is little bit loose but not much....

My question is, if problem is more likely that front suspension bushing or problem is with rear axle alignment, please help!!!

 

Hi Nicoj36
Thanks for reply, I was checking that one with toyota diler some time ago but turn out that steering angle sensor is only to read data, is not affecting steering wheel position and reset wont help, I also dont have any emergency lights on dashboard.
Regards.

 

thanks a lot, i didnt hear about that before, i will definitely check that out, a week ago i was in mechanic, changing all break pads, but i dont know about that pins you mentioned, so on next visit i will ask about it, in my car it pull left when breaking but also when normal drive(very annoying)
Did your car was pulling during normal drive? Did breaks was getting hot? Please let me know i am going to fix that Japanise limusine

 

Thanks mr nicoj36 I am going to do it, also pins, and we will se what gonna happen,

 

Hi mr Mendel, thank a million for suggestions, I can tell it might be it because when I was in mechanic waiting And car was raised up I was spining rear wheels, and there was massive difference between sides, left rear was spin freely, right rear very poor with noise like metal against metal, so like I mentioned to mr nicoj36, I am going to focus on that one, Thank guys I really appreciate your help

 

Thanks Grit, what kind of lube did you use for it please? I defo will going to work on that one, i have way more drag on right rear when spinning wheels when car is up, left rear spin freely, right cant do one turn, and makes noise, I am exited to try this, and i am surprised how priuschat forum is helping its good to be in Toyota family thank you

 

3rd Gen Rear Brake drag info? That very helpful Mr Mendel, I highly appreciate i will reply with result after visiting mechanic thanks again

 

Hi there Mr Mendel, today I had yearly national inspection NCT for my car and I recieved data of breaking condition etc, can you have look on that please, there is 27% imbalance

 

Hi ttou68, thanks for suggestion, how you will know is a bearing? I will go to mechanic soon, one thing I noticed is that is hard to spin rear right wheel compared to left one also noise of scratch of metal ..but no loose filling to the wheel, if bearing is damaged is getting hot?

 

Hi man, you was right, I did it and there is improvement, wheel is coming back more to center, still there is that pull but now is steering better thanks for your sugestion I also learn something

 

Hi there
I have update from my case, I went to mechanic today and we checked rear brake calipers, right wheel piston was out of position, we positioned piston as per your pic, and I see improvement on fuel consumption straight away and maybe less pull to left. my question is if I should check front calipers as well? please let me know. I have next visit in garage in one week time, I am going to change one of bushings

 

Thanks a lot
