I have a very slight vibration at 70 mph and it gets more noticeable at 75. At 80 mph it is very noticeable. I checked the front driveshaft and I get a little movement at the transfer case output CV joint. The CV joint is new and solid. The front output bearing seems to be snug but I think there is movement at the rear part of the output shaft.
I have been told there is usually some play in that area because it is a needle bearing and it fit is like the transmission input shaft in the pilot bearing in the flywheel. If it was a tight fit it would be difficult to get the output shaft part into the bearing during installation. I still think it is too much play and may be causing the vibration I am experiencing.
The main question I have is; should I replace the output shaft also if I replace the needle bearing? It seems to me that it would wear too and I may not have a correct fit if I just replace the bearing. Does anyone know what the correct diameter is of the front output shaft that fits in the bearing at the rear of the transfer case?
