legacy tyres wearing unevenly

the tyres on the front of the car are wearing on the outside on the passenger side and on the inside on the drivers side the rest of the tyre is still 75% i'v had this problem with the last 2 legacy's aswell all new cars. the last one the front anti roll bar was changed along with new bushings .there's only 30000 on the clock and haven't hit anything to put the tracking out this much anyone any ideas.

Something to do with your camber settings id say..four wheel alignment is what id check first

First port of call is always tyre pressures and wheel alignment if tyres are wearing unevenly.....

Failing that try turning more left hand corners harder to even it out a bit

as above...
camber issue...are the front shock bolts essentric (camber adjustable)????
dont think they are IMO...

no fixed position no adjustment on them
