Default Help me with these alignment results

Would the BEFORE alignment specs below cause these:

Whine About Tire Wear

Whine About Bearing and/or Tire Noise



It looks like all that was wrong was the Toe on the left pointed a little to far out and the toe on the right a little too far in. I don't feel any difference (maybe it tracks better.... hard to tell).

Its highly doubtful that that small amt of toe will cause a tire to "cup" or cause a wheel bearing to go bad. In my experience(5 yrs as a Honda dealer tech) most abnormal tire wear is caused by not rotating the tires on a regular basis. Of coarse, certain tires are more prone to odd wear issues and road conditions can cause odd wear patterns as well. What is your exact problem?

...sorry...d0000d....but Subarus are VERY sensitive to toe issues and bearings are not a strong point for these cars.

...and.......

That alignment SUCKS....BAD.....ya want as much neg camber in front as you can get and mebbe get some camber bolts to take a bit of neg camber OUT of the back.


....and......lemme guess...ya put springs on it and didn't get an alignment after ya slammed it-----RIGHT????

All cars are sensitive to toe wear and I am aware of the wheel bearing problems.

Next time I'll resist the urge to help.

...blown struts can also cause tire wear issues.....in combination with a bad alignment and a bad bearing----ya can get tire wear chaos.

It is strickly stock. The only non Suabaru parts are the HKS brake pads and Purolator filters. I can't remember even hitting a pothole since it was new.

ONCESIR, the problem I'm having is the outside of just the left front tire wore in an unusual cupping pattern. To be honest the left rear may show signs of similar wear, or I didn't notice when I rotated the tires (I do that every 5000). The right side tires have half their tread life left with even wear. In addition to this when I noticed the unusual wear I started thinking about the (what I thought was) tire noise I'd been hearing and a search of the forum is pointing me to bearing noise. I can't isolate the wheel the noise is coming from.

I wouldn't mind buying a Hub Shark or a Hub Tamer to change a bearing if I knew it would do something.

I have to drive the car 1000 miles later this week (trip postponed) and wondered if I would have problems.

Thanks

...if your car is strictly stock....you have problems to have that much rear camber....
Those 'before' toe settings will, without any doubt, cause tire wear issues

That alignment was and still is WAY off....not as bad as it was...but still off...and ya really need more negative camber in front


It looks like RWD alignment specs

Ok… The manual says, for a Turbo Sedan... See if my terminology is correct

Front

Camber (tolerance +/- 45 minutes) Should be -25 minutes Mine is
LEFT -0.6 degrees or -36 minutes
RIGHT -0.2 degrees or -12 minutes
Caster (common difference +/- 45 minutes) (what does common difference mean?) Should be 3 degrees 35 minutes Mine is
LEFT 2.8 degrees or 2 degrees 48 minutes(2 minutes out?)
RIGHT 3.1 degrees or 3 degrees 6 minutes
Toe-in Should be 0 +/- 3 mm (Each toe angle: +/- O deg. O7' 30”) (Total toe angle: +/- O minutes15 seconds) Mine is
LEFT -0.6 degrees or -36 minutes
RIGHT -0.2 degrees or -12 minutes
Kingpin angle (assume that is SAI) (tolerance: +/- 45 minutes) Should be 14 degrees 35 minutes Mine is
LEFT 14.5 degrees or 14 degrees 30 minutes
RIGHT 14.6 degrees or 14 degrees 36 minutes
Rear

Camber (tolerance +/- 45 minutes) Should be -1 degree 30 minutes Mine is
LEFT -1.4 degrees or -1 degree 24 minutes
RIGHT -1.5 degrees or -1 degree 30 minutes
Toe-in Should be 0+3 mm (Each toe angle: +/- O deg. 7 minutes 30 seconds) (Total toe angle +/- O"15') Should be -25 minutes Mine is
LEFT .02 degrees or 1 minute 12 seconds
RIGHT 0 degrees
If castor is positive does that mean the wheel is pushed back? Like the line through the ball joint and strut bearing point more forward than they should? Does castor being off in this direction indicate a body damge? Do I have a problem? What happened?

What should I have them adjust? It looks like everything is in spec except for what can't be adjusted.

How do you figure out what thrust angle in the manual is?

i'll tell you i had issues with my alignment similar to yours. it was that way straight out of the factory. i had been to three different alignment shops that said nothing could be done for it. after two a half sets of tires in 50K (and a bunch of mods so warranty wasn't an option) i finally found a shop that could correct it. it looked like the guy really earned his money that day. he was cranking like a mother****er to get into spec.
