I have a 1997 Tahoe and the steering is lose and when your turning to
the right it seems to drift and then it's find. Does anybody have a
fix?

Take it to the dealer and get a front-end alignment.  If this is the
first time it has had an alignment the dealer will charge you to
remove the "building plugs", these are plugs that are installed as the
car is built. Just keeps stuff aligned.  It's a rip off, to remove
these plugs, but the alignment you will get at the dealer is so good
that I have found it worth it.

Just tell them the problem and it could be just a simple steering box
adjustment.  Depending on the mileage the probem could be more
serious.  If it is 4 wheeldrive then the problems multiply.

Once you find out what the problem is, the dealer is going to give you
an estimate. So let us say the tell you the 4 wheeldrive front axle is
bad and it will cost a ton of money to fix.  You can go to just about
any autorepair shop and they will put in junkyard parts.  I do this
all the time.  I've had put in transmissions, front ends, rear ends,
etc.

Let us say the steering box is bad.  Do the same thing.  Depending on
the problem you can use the junkyard approach.  I only do this for big
expensive stuff.  If it stuff like frontend parts, tie rods etc.  I
would just replace with new.

More than likely it just simple adjustments to repair.  

I hope this helps.

first thing is to start with the simple stuff check your tires air
pressure this can cause pulls. check your tire for uneven wear this
can also cause pulls and is a sign of aligment out of spec.  Next if
you have a jack raise the front end of the truck, grab one tire on the
9 o'clock and 3 o'clock sides (left and right side of tire) shake back
and forth as if you were turning the tires lef and right, feel for and
play in your front end. repeat on other side. then go up and down on
both.  If a tierod is loose it will have play side to side.  If it is
a ball joint it would have play up and down.  Their is also an Idler
Arm and Pitman Arm in that would feel loose side to side.  The last
thing that could be wrong would be wheel bearings which you would feel
side to side and up and down.
Being a chevy tahoe I would bet is the Idler Arm--very common for
Chevys and GM''s.
Their are building plugs in the front for alignments called knock
outs.  They are for adjusting caster and camber on your alignment. 
they do cost more than a normal alignment because their a lot of laber
for a cheap part.
your best bet is to go to a tire shop deal them your problem and gave
them do a front end shake down and alignment check--usually
free---Don't go to the dealer unless you feel like spending A lot more
$$$.
