My mechanic said that the he could not fix the front end alignment because he can fix the toe but not the caster. what do I tell him to do it still pulls to the left.He is not to familiar with this kind of car I do believe that it is a 91 or 92 Subaru Loyale. it is awd car.

no vehicle make model. year supplied so the answer is generic but applies to most vehicles toe in is 1/8 -1/4 inch
caster 1 to 1 1/2 degrees and camber 1/2 2 degrees ( all measurements are positive
tire wear is the best guide to wrong alignment
wear on the inside or outside of the tire tread is alignment and toe -in
in the middle or on the outsides of the tread is pressure problems
wheel wobble at speeds ( 30mph up ) is castor adjustment, loose tie rod ends , ball joints and if the castor is approaching negative setting , will, not recenter the wheel after cornering
I suggest that you take the vehicle to an accredited suspension/ wheel alignment shop with experience on your make of vehicle and have it inspected
good shops will recommend that the rear is checked/ adjusted first as much front tire wear can be traced to the back being out

The way to do this is with an alignment purchased at your friendly neighborhood service shop.
Trying to count threads on the tie rod (or other means not involving lasers) is not a reliable way to
align your 1997 Nissan pickup.
The tie rod ends are what a mechanic uses to set the toe-in/toe-out component of your alignment.
The other 2components of your alignment are caster and camber.

It's toe-in, caster, & camber--all included in a front wheel alignment at an alignment shop--make sure your struts, link rubbers, ball joints, wheel bearings, & tie-rod ends are good first or they will tell you to replace them before alignment(or they should be replaced if worn). An alignment can cost from $35-$100--depending on whether you get a 2 or 4 wheel alignment. Usually the rear is okay--unless the car has been in an accident or has over 200,000 kms.(120,000 miles) on it.

caster is adjusted at the rear of the lower control arms. Camber is fixed and cannot be adjusted by normal means (though special off-set ball joints are available to do that) Toe in is adjusted by turning the sleeves in or out on the tie rod ends. None of this should be done at home though crude adjustments can be made in order to get the front end reasonably straight. Adjustments are made on an alignment machine that allows precise adjustments to all you mentioned as well as front/rear tracking.

Toe, I believe is tires pointed in or out like your toes. Caster, think about the casters on furniture that want to point straight in the direction of travel. Here is a good reference: http://www.aa1car.com/library/wheel_alignment.htm

What you are describing could be a toe in, toe out problem or it could be weak springs or overload condition.

If the guy/girl that told you there was no toe adjustment was a front end alignment mechanic, I would be inclined to believe them. If you have not spoken to a front end mechanic, you should.

Thanks for your question at FixYa.com

was your car in a wreck since you have own it?
that would be the only way anyone could bend steering or suspension parts.if your tires are leaning out on top,
it would be a part called"lower control arm assembly",
if you stand in front of your car with the steering wheel straight,and your tires are pointing in on each side,or pointed out instead of straight,that would be a "tie rod "
there is an inner tie rod and an outer tie rod end.
you need to take your car to a shop that does alignments,and have them tell you exactly what is wrong,you can even get lower control arm assemblies
from a salvage yard.but do yourself a favor and don't take your car to a MONROE or MIDAS type shop,they are only there to sell and make commissions! Find a normal shop that the owner is the mechanic.

The Caster should be between 2.3degreesand 3.3degrees,Camber should be between +.3 degrees to +1.3 degrees but I myself would recommend closer to the+.3 degrees and as for the Toe should be about 1/16th toed in to not more than 3/32 toe in.

If you have just spent the money on yierod ends I would take it to a front end shop and have them do a front end alignment there is much more to a front end then just toe in and toe out, they will set your caster camber and toe in for you

This sounds like a caster issue, add more caster
