Remove wheels, remove brakes, remove centre nut, remove wheel bearing, pull out axle, replace u-joints, reassemble.
The only hard part is getting the wheel bearing out if it's been in for a while (replacing the u-joints takes some pounding as well)...you need a 1/2" or 13mm 12 point socket for the wheel bearing bolts...the usual technique is to loosen off all three bolts about 1/8" and then pound on the bolt with the socket to drive out the wheel bearing...if it doesn't come loose, then back the bolts out another 1/8" and hammer some more. The proper way is a slide hammer but this works fine too. You will need a jumbo socket for the center nut (36mm?) and a tourque wrenc to tighten the centre nut to 175 ft pounds (I think), make sure the weight of the vehicle is on the bearing before youy tighten the centre nut to the proper tourqe.
Chances are the wheel bearings are not to far from being toast on a 92 , I like to examine and repair/replace all those parts at once, otherwise you end up taking it apart repeatadly to fix a different problem each time, i.e. front axle u-joints, wheel bearings, front brakes. Brake parts are relatively chgeap but the bearings are more pricey. I would strongly reccomend NOT using the cheap chinese wheel bearings, if you end up replacing them, they are not that much cheaper but don't really last at all.
Another annoying thing is that whenever I pull an axle shaft, it seems to be about 50/50 as to whether you will develop a axle shaft seal leak upon reinstallation.
