I'm replacing all of the rear suspension bushings in my Z (94 NA) and the axle (toe rod) bushing (Nismo Part #55152-RS520) has a rubber shell on the outside (no metal casing) with a metal spindle in the middle. Each side of the bushing has what I can best describe as an attached rubber encap that's a few mm larger then the rubber part of the bushing that pushes into the hub. On the bushing itself it shows the same part number as the stock piece (55152-33p00) but looks quite a bit different with the middle piece being shorter and the rubber end caps being larger and beveled. The metal spindle piece in the middle is the same length. I tried to press it in by lubricating it well but it just tears the rubber in the end cap. Has anyone replace these before that can provide some tips? It's almost looks like it's wrong part?
