Bailey, I purchased a Thrust Bearing Kit which looks easy to install, but I can not get on the "Retaing Ring" on at the end. The shaft has a groove at the end for it, but when I put on the last washer ring it leaves no space avaible to get to that groove. The groove is covered by the washer ring. I read the service manual on-line it says, "After reassembling the components on the drive shaft, it will probably be necessary to pull down on the shaft to take the end play out of it before the thrust washer and retaining ring can be reinstalled." I tried with some force to pull it down with no success. I was worried that if I pulled extremely hard that I might do damage. Do I need to clamp on to it with a pair of vice grips and pull down really hard? Suggestions are really appreciated. Thanks.
