How hard is it change the front passenger side U-joint in a 98 TJ? will I have to open the diff cover (does the front dana 30 have a c-clip)? And where is a good place to get a U-joint, I don't need top of the line but I also don't want to have to change it again in 6months.

No C clip. I just buy the normal U joints at C Tire.

jack it up

remove wheel

remove caliper and disk (use a piece of wire to tie up the caliper)

remove three bolts from the back that hold in the unit bearing assembly

use BFH to free the unit bearing (there may be another way to do this)

remove axle shaft (may or maynot see some oil)

use PA universal joint tool to push out old and install new universal joint

I usually scrap the crud out of the housing with a large washer on the end of a broom handle before I reinstall the shaft

reverse steps to reassemble

Haven't done it for a few weeks so I hope I didn't miss a step.

Spicer only if you ever plan on putting it in 4wd.

Spicer 760 is the joint.

DSI is another good place for them.

The hub bearing can be a real bear to get off. I have heard of people putting the tire back on so they can get more leverage. I had a heck of a time getting mine off the first time. One writeup on the web says to use a 2 1/2" bolt to get it off. Just put it in place and have someone make sure it doesn't shift while you turn your tire. Here is a pic. I plan on doing this next time I take mine off if I need too.
