Help - Opinions On U-Joints and coil sprigs: 89 XJ, 4L I6

Hi:

I've got about 190k Kms on my 89 Cherokee, I had the original front axel U-Joints replaced at about 160k Kms and now, at least one of them is gone again. I'm looking for advice on a better quality replacement than the last set - sorry I don't know the make of the last set. All I know is that they were not as good as the originals. I don't do a lot of off roading so my need is a longer life - as opposed to great strength - maybe you can't get one without the other?

What's the consensus on greasable vs. sealed U-Joints? I would have thought that greasable is the way to go, but my originals were sealed and lasted a lot longer than the greasable replacements even though I greased them regularly.

I also have a broken coil spring and would like to replace both fronts with ones that are similar to stock in terms of ride and height. Any suggestions?

While replacing the coil springs, I might as well replace the front shocks. Any suggestions on a good set of replacements - keeping in mind that my 4 wheeling is pretty much limited to snowy roads in ski season and the odd logging road in summer - nothing too challenging? I liked the original ride and would considered replacing with the original shocks, but I'm willing to go for improved durability if that's available. I don't want the ride to be any harsher.

While I've got this much of the front end apart, should I consider replacing anything else while I'm 'in there'?
