Alright,,,heres what I have,,,489 sure grip ,,cone style,,,tapered bearings. Terry and I looked it over good and the thrust block is missing (no wonder my axles wiggled around). I am really sure that my tapered bearings will be beat to hell and need to be replaced because of the lack of a thrust block (I think). So,,,if I go back with the tapered bearings I pretty sure I'll have to find a thrust block, buy all new bearings, seals and locks,,,or just buy greens,,,will I then need to buy a thrust block too? Does anone have a detailed diagram on how to install them? and finally were can I buy them In alberta on short notice,,,,,hows that for a question lol.
