I have a Ford 9", Open Carrier, 28" Spline in my '34 Ford. I had to use a slide hammer to get the axles out. It took about 3 good hits to get them to pop out. These axles have a sealed bearing with a bearing retainer. To put them back in, I slid them in as far as they would go and then I had to use a piece of 2"x4" on the end of the axle and tap them in further with a 5# maul. I realize that being a sealed bearing fitting into the end of the axle machined area I would have to use something to tap them into place. QUESTIONS: 1. Is this normal? 2. On one side, it went in too far and the bearing retainer was rubbing against the Oil Seal and scuffed it all up causing a noise. 3. I popped both axles back out and put a 1/8" washer between the axle housing and backing plate after allowing the bearing to extend past the axle housing about 1/8". According to a well know 3-rd member rebuild shop out West, they say it is normal for 9" axle bearings to hang out 1/8" past the axle housing. 4. How do you know how far to drive them in? 5. This is my big concern..........Can you drive them in too far and ruin the carrier bearings? Thank you for your input!!!!
