Here is the part from Amazon a little cheaper.
http://www.amazon.com/Rare-Parts-RP10471-Control-Joint/dp/B00DW5GFTKI commissioned Rare Parts to rebuild my idler arm a while back for 100 plus shipping. Initially I bought a TRW Moog and found out there are two problems with the TRW Moog idler arm.
Number one it didn't fit, my original has a weird drop head design, it actually looks bent but it's not.
Number two problem is that it was very hard to turn in my vise and had no spring action.
Rare parts educated me to the fact that factory idler arms are set up to have a spring action created by a pinch load between the star washers and the inner rubber bushing. This design helps the steering wheel to snap back to center when you turn a corner. I Chucked up the rebuilt idler arm in the vise it turned very smooth and did have the spring action. I was surprised that the TRW Moog part was so vastly incorrect in this respect.
Have you checked with Rare Parts to see if they can rebuild your existing control arms?
