Well, I finished the teardown of my read Dana 44 and ARB. I narrowed the excessive play down to the splines on my stock axles. The ARB looks great except for the spider cup shims and the splined gear shims. They just look like they should be replaced.
I also ruled out any current component as the source of the metal chunks I found inside. They must must be left over from prior damage and never cleaned out well. The chunks, however have left behind minor damage on all my races, even those installed on the axles just last spring. The inner pinion bearing rollers have scratches on them as well. So it looks like I'll be replacing all the bearings. The gears look good enough for me to reuse, but I'm going to get a second opinion on those.
That's what I know. What I don't know is, how to install the new pinion races, do I really need an axle housing spreader to install the new carrier bearings and shims, how to remove the old pinion bearing (Cut it off???)and I'm not sure what I don't know yet? And what all tools I'll need???
Then I'm wondering if I can upgrade the splined spiders within the ARB to 35, and go up a notch on the new axles.
I had previously started an article in Tech Reports, and will continue to update when I have time.
