RELATION OF U-JOINTS AND 4WD

I have a 1994 Jeep Grand Cherokee Laredo w/145000 miles and a V-6.
If I have a bad U-Joint in my front drivers tire, will it keep the 4wd from disengaging? Or from going into 4wd at all? Also how hard are front end U-Joints to replace?

Do you
have the same problem?

No it wont keep it from 4wd operation unless it is snapped in two, butv it will damage the axle shaft to the point it won't accept a new joint. It is not a hard job, just remove brake caliper and rotor and axle nut, then 3 - 4 (don't remember) bolts on back side of steering knuckle, that hold unitized wheel bearing/hub on, remove bearing and pull out axle and repl. U-joint, re-install, 1-2 hrs. Total. Tje bearing may need some persuasion to get out of knuckle(hammer and cold chisel, between bearing and knuckle). Ok good luck. Let me know how it goes.
