On my 30, the shims are out side the bearings as they are on my 44a. My wife's 35 has the shims sandwiched inside the bearings. I cut off my bearings & used the inner races as a pressing tool w/a dead blow mallet. Did the pinion bearing on & off with a press @ a local machine shop. If you want to see if you are into this check my "Wheel bearings turns into my axle build thread" w/photos. It's a 44a but the job is basically the same. I will admit to some short cuts that many on here don't agree with. It's not an easy job.
