My 74 Bronco is in parts all over the shop to address a few issues I’ve been putting off for sometime now. I posted some months back abut my axle housing ends being “oblonged”. They started giving me trouble again so it’s time to fix it for good. While it’s apart, it’s getting 4:11 gears and a Trac Lok to replace the 3:50/open but that’s a different topic.
With much research I’ve come to the conclusion I have 66-75 STD Duty (Large Bearing, Large Brake) Bearing size 3.150 Brake size 11x 1 3/4 Axle length PS 29.250 DS 26.937 Axle flange 3 1/2 x 2 3/8 x 1/2
Now for the questions.
1. Can the axle housing ends be machined and sleeved like cylinders in an engine block?
2. When looking for housing ends, do I have to worry about axle tube ID/OD or are all Ford 9 axle tubes the same?
3. Anyone ever bought these? http://www.ebay.com/itm/9-Inch-Big-...Parts_Accessories&hash=item5649d387d3&vxp=mtr
4. What is the axle tube ID on a 74 STD duty large bearing Bronco?
5. Does anyone know what the axle end tolerance should be in relation to the axle bearing size. If axle bearings are 3.150 how much bigger (in thousands) should the ends be to accept the bearings to insure a nice snug no spin fit.
