Default Alignment question?

Is a all wheel alignment necessary? I wanted an all wheel alignment and the guy at the shop said they didn't do it because it wasn't needed? Just did the fronts

Car still pulls left?

All 4 wheels can contribute to the car pulling one way or another so if a 2 wheel alignment didn't fix the pulling I'd suggest a 4 wheel alignment yes.

I feel that it's needed for all 4 wheels...they can wear properly, what do they care if your paying for it?

Ask them for a thrust angle alignment.

Only time you need a two wheel alignment is on a solid rear end with no adjustments.

On any and all normal cars rear is set up first and front is matched up to it. If your ass is ****ed up and you set up your face to it, guess how well its going to come out.

Run Run away from that hillbilly hackafix if you know whats good for you.

You still need to reference the rear to thrust in the right direction.

2013 wrx question - 4000 miles

Took the car in (dealer) for an alignment fix because it was drifting to the left and I had to slightly hold the wheel to the right - no pothole runs or damages btw.

After the fix, I have about 1/2 cm off center steering where I need to tilt the wheel slightly to the left. Is it worth taking it in the get fixed? If the wheel is perfectly straight, the car drifts to the right. I told the dealer this, and they said that because it is minor, it is usually due to the crown in the road. Is this accurate or should I expect to have a perfectly centered wheel?

I had a dealer tell me that the bolts were frozen on the rear and that they expect they would break parts if I insisted on the rear being done.

I had them just do the front. But I had replaced a front control arm so that's all I really wanted anyways.

They should at least check it... I went to bell tire for a 4 wheel alignment on my wifes truck, they put the sensors on all four wheels, but only the front were out of alignment. They didn't charge me for the full four wheel alignment. I thought that was cool.

Ofcourse, but all adjustments are done up front , so its still technicaly a two wheel alignment.

PS all modern machines require all 4 sensors on, it wont even let you go to adjustments or compensate till all of them are on. which leads me to believe they are likely using outdated "string" machines or worse....not the accuracy youd want on a sports car especialy if you enjoy long tire life

Would love to know if a 4 wheel alignment did the trick for you.

Subarus = all-wheel symmetrical drive. All must be adjusted to ensure the car tracks properly and that the power is distributed as it should be. Not to mention the fact that if your alignment is way out of whack, it will eat up tires and possibly foul up the differentials along the way. My shop always gives me a computer printout of the before/after measurements so I can see exactly what was done and why - and it appears by this printout that toe, camber and thrust angle are all independently adjustable on the front and rear. You'd be crazy to only do 2 wheels with all those variables.
