I still had to tap the race in about 3/16"s of IN.( after I heated up the carrier spindle housing, a big industrial oven can heat a big chunk of steel a whole lot better than my little ole heat gun) to bottom it out. Now the races are pressed in AFTER the parts come back back from the powder-coating facility. Once everything is assembled
right and snug down, it works like it was designed for. Remember the tail-gate
only swings about 95 degrees, its not a like a wheel bearing where it must with stand high RPM"s, even though the bearings are Timken Tapered Roller design, believe me the spindle and bearing/races are stout enough to handle the load. ( Designed for up to a 40 IN. tire and wheel )

Which way did you install the top bearing assembly? If I installed mine pointing down, there was too much clearance between the bearing assembly and the carrier, so the mount was sloppy. If I installed it pointing up (as pictured bellow), the mount was stable, but the nut & washer would not reach down far enough to tighten against the bearing assembly (shown bellow also).

So, if you installed it like this, you have a problem:



It's little hard to see, but a lot of the grease on the top bearing assembly is dark gray from excessive wear. I'm going to replace the top bearings because I expect they'll fall apart eventually. I had to push the bearings back into their slots.
