YJ front axle sound
My 95 YJ makes a knocking sound at the right front wheel. By turning
the hub by hand with the wheel off I can see the axle jumps a bit every
so often and makes this noise. This is with the wheels pointed
straight ahead. Could this be a problem with the front axle disconnect
or a bearing problem?
Thanks,

Re: YJ front axle sound
Check your outboard U-Joints first. If you don't remember changing them,
that is your first clue. So is a slight ring of red rust around the
rubber boots in the joint.
2nd place is the wheel bearing, but this usually has a 'growl' rather
than a 'clunk' or 'knock' Bearings are a sealed unit, plan on $125 for
the complete assembly.
Changing either the bearing or the U-joint requires removal of the
bearing assembly from the knuckle. If you live where they use salt in
the winter, this can be a serious pain to get out. It can take a simple
1 banana job and turn it into 4 hours of serious profanity. Use an
antiseize on it when reasembling.

Re: YJ front axle sound
I second the bad U-joint diagnosis.
I use a sacrificial bolt and a 5 or 10 lb BFH to remove the hubs. I use
jack stands, the jack and toss the tire under the Jeep before starting.
You can cut the steering side to side to get room to swing the hammer
onto the partly threaded in bolt. Soaking the joining area with a good
penetrating oil for several hours or days first helps I do live in the
rust belt and they are a serious pain in the butt to get out the first
time. I use antiseize on them before putting them back in.
I think you might find the bad u-joint has also taken out the inner axle
oil seal. Look into the tube when you pull the axle for oil evidence so
you don't have to do the job twice... That can be punched into the
vacuum disconnect area you have to have open anyway usually because the
connect cog can get out of place and takes a threaded rod with big
washers to reinstall. You have to suck the new seal into place.
