Slip Yoke Eliminator
97 F150, 5.4, 4x4. 60K miles. I have a severe slip yoke problem. I have tried the grease, worked for 2 days. One mechanic I called told me there was a modified yoke with a teflon coating that would solve the problem ( TSB 97-13-21). Another told me there was an aluminum drive shaft that would work (although he said this was only a temporary fix). Though research, I found something that intrigued me. It is a slip yoke eliminator kit. Apparantly it is used quite regularly when a truck is lifted.
The process is done by bolting on a flange onto the end of the yoke. Replace the existing drive shaft with a new one that has the slip built in to it. The kit costs approximately $450, labor extra.
Has anyone tried this? Were there any problems?

Interesting problem. I have a 98 that was heavily off-roaded. the yolk center was knocked out at some some and it ran open in for several years. (unknowingly) It has a 4 inch lift but I believe that is not a factor. The output shaft is severly worn. Tailcone removed the yolk had about .080 wobble in it. The bushing in the tailcone is a joke for alignment as well. I am lookin at changing out the output shaft, $220 for the part, or replacing the transfer case. (cheaper???) This solution might be an alternative. Drilling the shaft would be a nightmare. They don't list the BW4406, but state they do "ANY" transfer case. I went $320 into a driveshaft before I discovered the bad shaft.
