2004 Dakota Power Steering

Has anyone encountered a problem with the power steering becoming 'stiff' while driving? It comes and goes but only after the truck has been driven for a few miles. It feels like the pump shuts down for a few seconds and then it comes back on. Serpentine belt is OK. Dodge dealer cannot diagnose problem as it doesn't manifest itself when they take it for a road test. Any ideas?

Thanks. -Mike

are all your joints greesed up?

Hello Mike,
Did you ever find out what caused this.My truck has started to do the same thing.
Thanks Julius

It is probally the steering shaft,from the column to the rack and pinion with frozen up joints.I seen this one happen on a cutomer's 2001 or 2002 Dakota and it is a very common problem.The part is from the dealer only,the whole steering shaft.
