I'm sure someone has had this problem. My steering wheel suddenly has a lot of up and down/left to right wobble. My though was that the felt liner in the upper bushing either wore out or ended up falling inside of the steering assembly. The bushing is a year old from when I rebuilt the steering box and replaced the control rods and arms. I talked to Randy Gross about this as he helped me remove the old bushing that was stuck on pretty good. He said I could insert a plastic bushing over the steering shaft and into the large hole of the upper bushing - he just said the make sure there was some sort of lip that would lay on top of the bushing so it wouldn't slide in. Sounds great in theory, but I was wondering if anyone has ever done this before and if it worked for them. I'm really not looking forward to removing the control rods and arms and pulling the old upper bushing out if I can avoid it.
