I bought new steering head bearings for 99 400. I had my local shop press the new bearing on the lower clamp. I took my longest screwdriver and busted the handle off to use to drive the old race out. This proved to be a difficult proposition.....any tricks to getting these out? Will heat on the outside of the frame help? The race on both the top and the bottom are pitted a little but not damaged to bad. Any suggestions would be appreciated!
