My uppers are bad, but what do they do exactly? While driving the wobble is gone since I replaced the lowers, and I have no problems no except for I believe a strut bearing is bad, but thats a different issue.It's not always just the lowers, check all 4 of the rear axle control arms (or links). Very common problem. The fix is usually to replace the bad control arms. You can also try to replace just the bushings but they're difficult unless you're handy with tools.
well thats really for you to decide. The tools I used were: half inch drive rachet with I believe 14mm for the nut and 16mm for the bolt along with a breaker bar. I got two of the bolts off using those tools. For the two bolts holding the LCA to the axle I used a combination of angle grinder and sawzall with lots of blades. It is just time consuming, the actual process isn't really that hard just REALLY long...awesome, thanks for the advice... I figured this project was out of my fixing-car-skills league

Not true. I only replaced the lowers and that cured everything but the jittery rear axle over bumps...Any sway or wobble will be cured by simply replacing lowers but I would check the uppers as well and replace them if they need it simply for safety's sake...ill be getting into that this summer, Im just hoping that the uppers come off easier then the lowers.check you rear axle upper links, craw under the vehicle you should see there are 2 upper link connect to the rear axle, this is the common problem for the pathfinder from 1997 to 2000, you can buy the part replace them your self, about $150 at the dealer
Swaying indicate your rear upper link had collapse or bad bushing,if your pathfinder rear end fish tail when driving or go over a bump, then replace the links will fix this problem, prolong period will also cause the lower link bushing to damage which will cost more to fix
