Hey Guys,
Was wondering if you could give me a little help. It seems a vibration has found its way into front drive train of my Cnd spec. 70. Comes about near 25-30 MPH. I might have started feeling it last winter while cruising through some snow at higher speeds ~45 MPH. I took this as a sign to rebuild/replace/repack my birf's that were leaking which I did last spring.
Symptoms:
Hubs Locked 4hi = Vib
Hubs Locked 2hi = No Vib
Hubs Unlocked 2hi = No Vib
Hubs Unlocked 4hi = Vib
I don't know if I've gone fast enough in low range to ever notice it. But it sure sounds like a T'case bearing to me and to top it off it looks like a little bit of oil is leaking down the front drive shaft. Plus if it were bearings in the diff. then it would vibrate when the hubs were locked even in 2hi right? What I am most confused about is why would these bearings/seal fail on the front side of the T'case or front diff. when there hardly used with respect to the rear parts. Ok so what do ya think ? I’ve never tore into a T’case or anything so I am clueless.
-Thanks
Noah
