I have done 4 bearings on my 126's. No big deal at all. I made my own special wrench for this slotted nut. I started with a 1 9/16" socket and did a little grinding to fit the nut. It took all of an hour using a small air driven abasive cut-off wheel. The rest is simple and straight forward. Red560sl, it sounds like you have a well stocked tool box and this task should not be too difficult for you. I have a lift so things were easy to get at. It does take some torque to tighten the nut and I used a long "torgue amplifier" if you know what I mean. I used a "air hammer" to remove and install the races. Easy.
Here is a photo of my handiwork.
