Well, it's not really as simple as that. But the best policy is if you aren't having problems or tire wear - don't mess with it.
The easiest thing to adjust is toe-in on the front end - but that's not the end of it. Igf you are having problems other things can be done.
Minor Caster adjustment can be done with offset bolts from the dealer. Even more Caster adjustment can be made IF you have adjustable arms.
Camber adjustment can be made with adjustable or offset ball joints - a pain to do.
Caster and Camber rarely need attention unless you've installed a big lift, changed the suspension, or bent something.
If you do much wheeling you WILL bend the stock lower control arms. requiring replacement.
As far as the rear goes, about the only reason to do a 4 wheel alignment is to check the Thrust Angle, and then only if you are experiencing Torque Steer - it pulls one way on accelerastion, then the other on deceleratoon.
Thrust angle is the front and rear axles are not parallel. You can check that yourself by measuring along one side front to rear axle to axle and comparing it to the other side.
But beware - there are 2 types of "4 wheel Alignment." One the guy checks the front, then turns the vehicle around and checks the back. It's not very good.
The non-scam ones attach instruments to all 4 wheels at once, then measure the interrelationships.
Save the 4 wheel alignment for the front wheel drive rice-burners.
It's no wonder the country is falling apart - stupidity abounds!
