Steering System Idler Arm running torque

[Bill B.]

Hi everyone!

I have my steering system down in order to remove my oil pan to install a windage baffle. While I had most steering rods disconnected, I noticed that my idler arm (6" length) took a force greater than 12 lbs at the end to move it. Once in motion, I do not feel any lumps or high spots, but am just concerned if this was abnormal or typical.

The idler arm is a Moog brand, stamped "Moog Problem Solvers". I only have 3,500 miles on the steering system (all new components), but I can't recall if it was that stiff to rotate when I was installing new some 5 yrs ago.

The 12 lbs in a 6" radius equates to approx. greater than 6 lb-ft of torque to rotate the arm.

Thanks!

After doing some research, I have just ordered an AC Delco 45C1014 Idler Arm for $43.79. Suspect that the internal nylon bearing sleeve might be getting fetched up from the heat of the side mounted exhaust pipe on the passenger side. The last piece of evidence was the disclaimer in one of the larger automotive parts supplier's website of the Moog P/N K6100 item indicating "Not Compatible with Optional Side Mounted Exhaust".
