I have finally gotten the idler off of my car. It was an adventure to say the least! My passenger front wheel was wobbling side to side about 1/8" when I had the car jacked up. The wobble came from about 1/32" of end play in the idler. I just took the cap off the idler to see how the end play was set and I cannot find any way that it can be adjusted. There is a gasket ( in good shape ) between the cap and the flat top of the of the idler shaft and nothing else. Could the steel flat top of the idler shaft be worn enough to cause the end play? If I take the gasket out and put the cap back on without it there is no end play at all and the arm is difficult to move from side to dide. Do I need a new idler shaft? There is no side to side movement of the shaft, just end play.
