So I have this periodic/intermittent harmonic vibration in my Jeep. It sounds and feels like it's coming from the driver's side front tire area. I pulled the front driveshaft to make sure it wasn't an out of balance or bent driveshaft. Didn't make any difference. So as I was driving today, it seemed that the vibration only seems to come when the wheel is turned....regardless of how slightly. This led me to believe it was a front axle u-joint in the dana 30 going bad. But I don't see any leakage, it doesn't appear to be loose at all, but it also has no valve to grease it, so I'm thinking it may have just dried and be slowly wearing away the needle bearings.
Is there any way to tell if the u-joint is on it's way out? I'd just wait until it snapped, but I don't want it taking the ear(s) of the axle ends in the process.
or should I just bite the bullet and replace it, and if it doesn't make any difference, keep the old one as a spare?
