After having serious vibration while braking , got van inspected and was told that Idler and Pitman arms have to be replaced immediately. I picked up manual at the store, but there isn't much information about how to replaced them.

Does anyone have any ideas and recommendation on how to replace them.

Thanks in advance.

 

Your idler arm and pitman arm have nothing to do with your vibration while braking. You need a pitman arm puller to get the arm off the steering box. You will need an alignment after all is done.

 

Thanks.
I will know more by the end of day.
