Rear Allignment on Hatchback 07 Yaris

[roneezy360]

I recently had an Allignment about a month ago and noticed my rear tires were still crooked. I didnt care at the time but I've been driving my Yaris for about 1-2 Years and I can actually feel every bit of movement when driving my baby. In the streets its fine but when im in the freeway hitting 70-80mph I feel crooked going straight and tend to go a bit to the left and right and after looking at my rear wheels my left rear seems to be facing the engine a tiny bit while my right rear is facing my engine a lot more than the left.

I know shops dont usually mess with the rear only with the front but what should I do? I want my rear straight and fixed not only because this bothers me mentally but also because its uncomfortable to drive. Im going to go to the shop tomorrow, can anyone hand out advice on what to do? What to say?

I just want this problem fixed lol.

most shops wouldn't even think to look at the rear wheels on a fwd car. Find someone with a great laser alignment machine and have them do a 4 wheel alignment. Just let them know you think the rear is misaligned and they should take care of it.

last time i check rear cannot be adjusted..

I could swear this is a second thread about the same thing. I believe you were asked before if you got a four-wheel alignment.

If you do, it will show with a printed copy what the settings were before and what they adjusted. Posting it here will result in better replies.

You can also post pictures of your car showing the crookedness in the rear, since it is apparent to the naked eye.

it isn't fully adjustable, but that does not mean it cannot work its way out of alignment. Or that something could not simply break.

i think rear wheels can be adjusted using shims.. it is better to find a place that specializes in wheel adjustment

The rear is considered non adjustable, however you can dial it in if need be. I used feeler gauges http://www.google.com/search?q=feeler+gauges&hl=en&client=safari&tbo=d&source=lnms&tbm=isch&ei=xLCIT52dC4iD0QHiwtHeCQ&sa=X&oi=mode_link&ct=mode&cd=2&ved=0CKwBEPwFKAE&biw=768&bih=518.
While it is on the alignment rack, you loosen the 4 bolts holding the hub and slip the gauges in as needed ( in between the torsion beam flange and hub). It is time consuming though... And expect to pay more than the
standard alignment rate. Also, I doubt any normal shop would even do this... Your best bet it to bring it to a performance shop.

This is how you properly align the rear wheels on an Echo/Yaris (and obviously a Prius as well):

My alignment guy, who also aligns winning race cars, took my car from almost 0 camber and -1/2* toe in to -1.5* camber and 0 toe.

feeler gauge trick is pretty cool, thanks for that

now that is the type of alignment place i want to go to. I'll pay a little more for someone who knows what the hell they are doing and knows how to use bolts and shims to perfect the alignment.

Well I went to a few shops and they said they couldnt adjust the rear. So i dont have a choice but to find a performance shop soon.

The rear is adjustable with a shim I thought.... I've installed several in fwd cars. My alignment machine at would will ask for the brand I'm using and print a trimming template accordingly. Any decent place should offer or tell you about that....

[Blown_xa]

We sell those round shims... But they are really a big trial and error. You can't do it with the alignment targets on the wheels because you have to keep removing the hub if you have to reset the shim. I also don't like the fact that it is a composite/ plastic. So over time it will compress and the hub bolts can loosen. I came to use the feeler gauge technique instead. Of course it is my preference, but just saying.

[Golddeenoh]

metal parts vs plastic for suspension, I would trust the metal over plastic. feeler gauge or make your own shims. even when i worked on howitzers we used brass shims so trusting metal makes more sense. I would have to test a plastic and see how it hold up before I go to all the trouble of calling it good or trusting it to last.

My alignment guy aligns winning race cars this way... it probably works just fine ;)

I haven't had any issues with the composite shims yet. Asfar as the trial and error my alignment machine prints off a pattern I can cut the shim to. Its not surgical but it get has been getting me in spec. But I've had it for a month or so.

Also, FWIW, I haven't melted mine after 5 track events... but the drums on the rear dont get very hot. The front wheels and lug nuts get so hot I sometimes have to wait 30 mins to take them off.
