Vibration on hard right turns
 

Not sure what the deal is. I just got all 4 wheels balanced, and I still have a rhythmic vibration that I feel through the steering wheel. Thoughts?

check to be sure the wheels are properly mounted.

Do you feel the vibration when going straight or only on hard right turns? are you braking in the turn or off the brakes? Doesn't sound like wheel balancing or mounting to me if you don't feel any vibration except in that particular circumstance. stock wheels and suspension? recent alignment or work done?

Is your car lowered, or do you have overly wide tires/wheels?

as the responses have suggested, you need to be more specific in order for internet armchair mechanics to be able to diagnose.

how many miles do you have? check your wheel bearings.

turn harder?

Kw v3, rpf1 17x9 245/40 mpss.
Car has just under 80k miles.
Only feel the vibration under hard rights, not when going straight or left . No braking midcorner.
Come to think of it, my mechanic (neal@theracersline) did mention my front passenger wheel bearing was in so so condition.

That would do it^

Is a wheel bearing something the dealer would replace under warranty, or is it considered a wear item? I have the extended warranty until 125k miles.

Your mods will make any warranty claim on wheel bearings sketchy at best. A wheel hub is not that expensive to buy, especially front.

I don't think that's it because the passenger side is unloaded in a right turn. Check for bent wheel or belts slipped in tire. The latter is especially hazardous.

edit: actually, yeah, maybe if the bearing was downright floppy. That's not so-so, more like dangerously failed.

how long is the powertrain covered? Ehh, might as well try a dealer. If it's a subaru USA warranty they get paid pretty well, so may be willing to do it.

This is not a powertrain issue. Powertrain would be everything up to the axles, wheel bearings are under bumper-to-bumper warranty.

And for the record:

Larger wheels (esp. lower offset wheels) tend to decrease the life of wheel bearings via increased load on them.

Look for tire rub marks could be right or left side.

of course:
so OP: go look to see what your extended warranty covers. doesn't hurt to try, the dealer gets paid by scion so they may not care.

Front wheel bearings are not covered under the powertrain warranty.

Rear wheel bearings are covered under the powertrain warranty.

Given that OP has issues with the front passenger wheel bearing... yeah, it's not going to happen if that is the cause of the vibration and will be subject to the regular (or extended) warranty. And given the mods, they will deny it.

Meh. It's just a wheel bearing.

even so. It's not that hard to remove the front hub. At least it's not awd with the axle in the way
