Front yolk
I bought my 94 grand about a month ago. When I got it the guy who sold it to me said the yolk bearing? needed to be replaced and thats why the 4x4 wasnt hooked up. I assumed he meant the pinion seal because it was leaky. I got under there to check it out and i noticed the entire yolk was loose. Not sure if this is normal or if i should expect to replace somethimg else when i go after the seal.
Its a 94 with a 4.0 i6. Dana 30 up front. Here is a video to he yolk.

Old fart with a wrench
What Bustedback said is true. If the driveshaft yoke is loose AT ALL, chances are the pinion bearings are toast. Long story short, the rear axle in my 97 blew up because a transmission shop replaced my pinion seal improperly, resulting in the pinion bearings disintegrating at 65 mph! Differential service is an exacting procedure and should be left to the professionals, UNLESS you are sure of what you are doing. It's even MORE intense than repairing a transmission.
Most guys just install a used axle when this happens. I'll bet you are the guy who just asked about why your jeep moves in park, right? Running a 249 transfer case without a front shaft can ruin the viscous coupling in it as well. Just be aware of this.
Sorry, you're not that guy, I just checked.

So im guessing to have the front and rear seales and possibly bearings replaced, thats about a $600 job from a good 4x4 shop? I would use tarhel 4x4 here in Charlotte.
