I posted a while back about some squeaky noise coming from the steering when
I make very tight turns, this noise comes from the inside of the car.  When
I took my car in for scheduled maintainance I told them about this noise.
They told me later on that this is probably a U joint loose or broken inside
the steering column.  The cost to take it apart to see if it is this U joint
is $400 and the cost of this part is about $100 plus misc charges it will be
about $625 and since it takes two days to do it I need a rental car it will
end up costing me more than $700.  Can someone tells me if this U joint if
broken or loose is it something that will affect the function or safety of
the car?  The dealer did not seem too concern and told me I can wait a while
before doing this...

TIA,
