Hey guys, hope somebody has some advice please. I have a 1981 hilux 4wd that's a complete pos and ex commercial/farm truck, I've finally had time to start working on it. Rear axle seal was leaking, got the 4 nuts etc off, axle came out with a gentle tap of the hammer, changed the seal. Dilemma is the axle won't go back in, and a plate with RN on it blocks it from the inner splines halfway. Said RN plate is stationary and not loose, anyone know what's up? Pulling my hair out, thanks for any info. In the picture you can see the plate on the bottom
