Car won't start

Just had alternator, water pump, all
belts replaced, when I got car back it
made  loud noise  coming from front
end.  Was told bearing needed
replaced. When I got  car back it  now  
won't start if  it's warm. When I try to
start it,  it  makes no sound at all,
although all dash lights  come on..
after moving gear shift around it will  
finally  start.
