JD replaced numerous walkers, walker brgs and walker shafts since the 9000 series combines came out, because of endless problems they had with them. I think the shafts should have been a larger diameter. You can easily shake the entire walker system by pushing up on one, without too much effort. If JD won't warranty for you, you can shop around for aftermarket parts which are as good for a better price. One you could try is loewen. They supply walkers and walker blocks.
