Z Pulling Left
 

I'm not the smallest human, and I've found it highly annoying that the Z pulls left a tad when I'm on the highway. Tires are fresh and suspension recently aligned. I noticed this pulling decreased when I had 70 lbs of ice in the passenger seat area.

I'm wondering what can be done to fix this, aside from welding a box together, mounting it to the passenger seat bracket, and loading it with lead bricks (we did this at a race shop I worked at in my teens.) Appreciate any thoughts or feedback!

Find a different alignment shop and do another one
Also inspect suspension components for damage and tires for uneven wear

Like member OptionZero has suggested have it looked at by another alignment shop.

It could be the toe is off or the wheel needs to be balanced If that checks out then possiblylook at the brake caliper.

Check your air pressure.

Next, switch your front tires left to right, right to left and see if it still does it. If it still pulls to the left. You then have ruled out radial tire pull. If it quits or pulls to the right. Then you know it's in a tire. Do this first because it doesn't cost any money if you switch the tires yourself.

Next step would be an alignment shop.

I would:
1) Do what Rusty told you to do. . . If nothing then:

2) Go get your tires balanced (for good measure) and an alignment, while at it, tell them to check your tire pressure.

I say this with no offense to anyone but if you are particularly large person, your weight may cause the alignment to be off when driving. To compensate for this, you can get another alignment but have them align the car with you in it. This should fix your car veering to the left when driving IF the problem was indeed the alignment.

Or get another fat person to sit in the passenger seat. :stirthepot: :wtf2:

See this is what I was getting at. And that's what I thought would be the solution.

Whatchumean "another?" This is all muscle, friend. I drop the trans and bench press it back into place for my daily workout.

:rofl2:

um . . . isn't something wrong with your suspension components if the weight of a driver is enough to disrupt the alignment?

How much left are we talking about?

Are we talking about nano of a degree over a mile or is it like driving an old work truck they had never been aligned?

Both good questions. We're talking 14% of the GAWR sitting in the driver seat. And the deviation in question is a very slow but noticable left drift. Could just be Illinois garbage roads are poorly graded. But I've always figured that if the interior was not designed with someone of my stature in mind, the suspension might not be either? Just thoughts. My knowledge of suspension is limited to:

1) it involves springs and gases.

2) if you unbolt the FUCA and pull the coilover out of its mounting holes, the steering knuckle will obey Archimedes/Newton and punch you in the face.

(Not really but you get my drift. Get it?)

Because of the crown in roads, many alignment shops adjust so that the car will pull a little to the left. Maybe your shop over did it.

As a temporary fix, you can add a little bit of air to the left tire. I'm assuming you've checked pressure on all four corners already.

That makes sense. I have lifetime alignment with douche-stone and I'll be taking it in soon. I'll add some pressure to the left front. And yes I used an electronic meter on all four and they were equivalent.
