The pullling to the left , you may have knocked the alignment off. The left side is under caster or the right is over caster. You bent something , upper or lower arms. If a straight axel, it may have bent it.
Caster= pull to the left or right ( has to be realy out to effect tire wear)
Camber = uneven wear ( about 20 % tire ware )
Toe in /out uneven ware ( about 78 % tore ware
Clean all the under side and wheels and disks and the wheels. Do not use the soap for motors.
The hard part is to find a GOOD alignment shop. Go to the dealer for the best work, It will cost more in the short term , but alot less in the long term.
To may halfass shops out there
