Uneven tire wear: Outside edge.

[Hi-Ho Silver]

Thanks for your help and guidance withthis fellas.
I took my car to get aligned and guess what was discovered? The technician discovered a lot of play when he moved the front wheels.
As a result, they are recommending that inner and outer tie rods be replaced. (estimate $423.00) I declined and have already ordered the parts from RockAuto.
Any idea why they would have failed so prematurely? I changed these 37k miles ago.
I have never changed the wheel bearings, (car now has 158,720 miles) I never been too eager to attempt a wheel bearing repair, It seems everyone who has attempted this repair has had a bear of a time. Also, going around town asking who willbe willing to use their hydraulic press to pop them in/out is not very appealing. A few years ago, (before I discovered this forum,) I went around asking who would be willing to do my water pump (with my own parts) and most shops looked at me as if I were crazy. Also, I don’t know what all the symptoms are. I certainly do not hear any grinding or whining coming from the front end. Do you all think the wheel bearings should be changed?
