More progress on the R32 suspension rebuild. The kingpin bearings are part of the upper suspension arm, and are theoretically replaceable. Nissan sells the replacement bearings, but the lower bearing is not easy to get out. It is inside a housing that is smaller on the other side, so you can’t get behind the bearing with anything. I got the first one out by using a dremel to slowly cut the bearing in half. That sucked. I got the second one out in 1/20th the time with an impact hammer and a well positioned bit. The smaller upper bearing is a very generic part I could get off Amazon for $7, but the lower bearing is an unusual size (31mm inside), so I had to spend $50 a bearing for those. Fortunately these bearings are the same on the 300ZX so they are available in the US. I also got all the bearings removed from the hubs and carriers, so I just need to get the new front ones and I can start reassembly.
