Tire wear, all 4 inner

On all four tires the inner ridge of the tire is worn flat. This vehicle has had a few owners and I know nothing of its history.

 

What on these isf Subarus would cause all the tires to wear like this, or could've another owner swapped front tires to the rear because of a bad alignment chewing them up?

Driving the vehicle tracks straight, but slightly goes right eventually, I understand proper alignment should do so for safety sake.

 

 

 

What can we check that may be causing these tires to be destroyed?

Previous owner might have slammed it in the past. Camber is most likely why your tires are wearing on the inside edge. Put a level on each wheel and see how far off it is. I would most likely bet it's significant.

Negative camber causes what you're describing.

It's possible age and mileage could have gotten the best of your previous alignment, whenever that last was. If you posted in the proper section for the MY of which your car is, then keep in mind it coming up on 16yrs of age and so it everything it's built with. Bushings are more than likely old and cracked, a glance under might reveal bent suspension arms from any previous ownership —all in need of an alignment after replacement. Early-model Outback wagons were set up with a decent amount of negative camber from the factory, but were still within spec. Whiteline's KCA399 rear camber correction kit fixes this. I can't speak for the Legacys or Outback sedan.

 

Also, you car may be tracking right due to a potential road crown.

08 legacy 2.5i automatic. has had engine issues and cv joint is split.

Yeah, still working on identifying the engine thing unless it a cv thing. The tires we just learned of this excessive wear on all 4 after removing them to clean much off that was causing a vibration issue at 60mph,which solved that problem.

 

Are the rear Subaru joints adjustable? It all looked fixed to me, this is why I asked if maybe the other owner had bad alignment that was eating tires.

 

Im in CO and to the road crowning comment yes they do, I'll assume thats aids is the light right pulling, it doesn't worry me, but the tires are pretty bad and understandably we would want to put new ones on if the suspension is causing wear.

No, that's backwards. Yes, you would want to put new tires on, but NOT if the suspension is causing wear, for the next set of tires would end up like the last. Any issues that lie with your suspension should be triaged before your alignment, otherwise it may always be off.

 

Subaru built our cars with eccentric bolts to make minor corrections to the factory alignment. There are camber bolts found on the lower strut housings up front. And more found on the rear's most forward lower control arms (inner portion of the arms). Toe can be adjusted via the front tie rods up front. And the rear, via the most rearward lower control arms.

Can an accurate self alignment be done on these vehicles ir is that out of the question and it needs the machine? I worry about taking it in as the bolts look crusty underneath, ide hope a shop would really do the work.

get pb-blaster or similar stuff (not wd40) and spray every bolt/nut in your suspension, every day until things can be turned. Although if that rusty, you might be buying parts to replace. It's common to replace when rusty.

 

If a shop does the work, they usually replace the broken stuff. Try to find a subaru specialist rather than a random shop. The specialist will have a much better understanding of how to do things.

 

Refrain from upgrades.

 

If the cv joint is leaking, it's better to replace the entire axle than reboot.

 

The alignment should be set to factory specs. Many shops have the junior guy do it and good enough is usually pretty bad.

Go to a Subaru dealer and have your car aligned, I only go there and never have had a problem. Of my shop that built my car.

 

Also on the reboot stuff, it's ok to do if done correct, and by real subie shop, I had mine redone because you really want to keep the stock axels. the green ones. Or order from Raxels and they custom make subie axels that are better then stock. I have had them on my legacy and they are done right.
