Anybody have the specs on the idler arm allowable movement for a 3500 IFS 2WD, it is not in the service manual. One would think "none" but there has to be a little bit.

 

Actually no, there isn't. It shouldn't move AT ALL. At least, not up and down at any rate.

 

I take a pair of channel locks and squeeze vertically, then hope for no movement. Bad rod and idler bar ends can cause a wheel shimmy. Especially when you drive over the railroad tracks at a crossing.

 

Thanks for the info guys, for those who might be interested, when buying steering parts, the company "Quick Steer" is Moog at less than half the price, same part numbers or at least is was on the idler arm for my pick up, look into it if you want to.

 

Most part #s will cross reference. I line MEVOTECH cheap and durable. I use them on my 2500
