drivetrain

hey, so i replaced my universals , i was having lots of racket from them and i thought my problem would be solved lol, well i was wrong im still having noises, i dont think its from the engine because it only happens when you start driving, the wheel bearing were changed out too, the noise increases in frequency as vehicle speed increases , some starts you dont hear anything , and other times it is very embarasing , its a metallic rubbing or grinding sound . when i have in 2wd and i go underneith and rotate the front drive shaft inside the diff or the tcase it makes a little click its hard to tell which , should it be really smooth and make no noise when you turn it freely? it feels pretty smooth but it does make a noise. the main noise from starting and stopping in town driving is a loud metallic rubbing noise.. it could be anything and its killing me to listen to this and have people stare lol! i really dont know what to think anymore

I do feel your pain, believe me. Jeeps are nothing like trying to diagnose a simple 2 wd vehicle.
If it increases with speed, it could be the transfer case, but so do other components like the rear drive axle.
A damaged clutch pressure plate can make some pretty crazy noises if the pressure plate was damaged during install. It does happen as there is a wrong way to install, and uninstall one.

Yes, my 90 YJ front driveshaft rubs on the exhaust pipe under heavy load, like climbing a hill off-road. Doesn't make a lot of noise, but I can see rub marks on the pipe and shaft. At rest, there's about a half inch clearance between them. Motor (4.2L) mounts and (automatic) tranny mount have all been replaced but it still rubs.

Possibly transfer case chain has streached and rubs the bottom of the case. Jack up rear so both tires off the ground. Turn driveshaft by hand and listen. If that's not it
..maybe you chipped a spider gear in the rear end.

to change the axle bearing you just jack it up, remove diff cover, remove the little bolt on the carrier, push the pin through, the spider gears will come out. remove the wheels, push the axles in. then inside the differential there are C clips that hold the axles in where the other 2 spider gears are, remove them. then slide axles out. then you will see the bearings. remove them and replace them.



right behind this seal is the bearing
