The main cause of steering wheel off-center is toe misalignment or rear axle misalignment. Toe can fall out of adjustment fairly easily as a result of daily driving, so you can imagine the effects of pounding it through 4WD trails on a regular basis.
Toe is designed to preload the steering linkage to remove play in the system. You can visualize toe angle from above; toe-in, or positive toe, is displayed when the leading edges of the tires are closer together than in the rear. Toe-out, or negative toe, is when the leading edges are farther apart. Zero toe is when wheels are pointed straight ahead and are parallel to each other. A slight amount of positive toe is preferred for most vehicles.
Improper toe angle isn't the only reason a steering wheel won't center. This phenomenon can also be caused by the steering linkage not being centered when toe was adjusted in the first place. This can be corrected by recentering the steering wheel and readjusting toe to proper specs. A bent steering arm or linkage component can also cause the steering wheel to be off-center. I've also seen this occur due to loose steering arm bolts. An off-center steering wheel contributes to tire wear because as the wheels are turned off dead center they turn toe out and increase tire scrubbing.
Sometimes an off-center steering wheel is accompanied by a wheel pull to one direction or the other and could be the result of a damaged component somewhere in the vehicle - a bent axlehousing could be throwing off the rear toe setting (rear toe setting is often overlooked). A bent frame or overly worn suspension bushings can also be the cause. If your wheel is off-center and also pulling, it can be as simple as incorrect tire pressure from side to side. Memory steer is another effect that is usually associated with an off-center steering wheel. This is when the steering wheel returns to an off-center position and can result in steering pull or drift after completing a turn. This can be caused by binding in the steering linkage as well as power steering system issues such as leaks or improper hydraulic pressure. Steering linkage bind occurs when proper geometry is not maintained in lifted vehicles.
Many 4x4s don't have factory provisions for adjusting caster and camber and rear toe and camber, but the front toe setting is easily adjusted. Toe is controlled by the steering linkage. By loosening the adjusters on the tie rod and shortening or lengthening the tie rod by turning the ends, toe angle can be adjusted. This should not be a substitute for regular professional wheel alignment jobs and is simply a tip that can be used to put off frequent trips to the alignment shop due to regular trips to the trail.

Before
determining toe angle and/or performing adjustments, it's a good idea
to start the engine and turn the steering wheel side to side to relieve
pressure in the system. Then, turn the wheels straight and shut off the
engine. You should also roll the vehicle back and forth a few times between measurements.
Get
someone to hold the other end of the measuring tape and measure the
leading toe distance. This is the distance between the leading edges of
the front tires. You'll compare the results to the distance between the
trailing edges of the tires directly opposite from where you took the
first measurement.
The
higher number will indicate toe direction: higher number in leading
edge indicates toe out; higher number at trailing edge displays toe in.
Larger-than-stock tires require more positive toe for best results.
Once
the necessary measurements are performed to determine what the current
toe setting is, you can loosen the bolts on the tie-rod adjuster sleeve
so that the tie-rod ends can be rotated. Don't forgot to tighten the
adjusters when you're done as damage or injury could result.
The
tie-rod ends thread into the tie rod. The ends can be threaded in or
out of the tie rod to make the assembly longer or shorter. Longer
creates more toe out; shorter toe in. Don't make huge adjustments all
at once. It's best to adjust and measure a few times to achieve
appropriate setting.

I hope this helps you if you were looking to do a toe alignment yourself if you have decent knowledge of component location on a jeep.
Their is an alignment for every car. you should have all the parts replaced that have to do with the seering linkage. Other wise the shop you have to take it to will not do an alignment on it. Your local auto repair shop should be able to fix you up with the parts and the alignment you need.
Yes there is total toe is adjustable and so is caster both on the front. i hope someone didnt tell you it was not if so go somewhere else.
