Dana 30 Spindle Damage

[inthegarage]

Hey Everyone,

I'm in the process of replacing the brakes on my 1980 CJ7 with a Dana 30 in the front. After I removed the hub (and the two poor spindle nuts that had been beat on with a chisel by the po), I noticed some unusual marring on the spindle surface.

Any idea what would make these marks?





The hub bearings look newer and say they are manufactured in Japan, so I doubt they are the original. I'm not terribly concerned about the spindles themselves, I more or less or curious and just want to learn if this something common or has a better name than "spindle damage".

Thanks Everyone!

I would think you could file down any high spots and be good.

Looks like someone used a hammer at one time to knock the spindle off.

Ugly, but clean up the bearing seating shoulder with a file and you will be back in business. Sure the spindle will still be bruised but it will work.

^^^^ This.

Rather than investing in the correct tool to pull the spindle(s), some knucklehead grabbed a BFH, without a 'soft face', and smacked the spindle. Probably tried to stick a screwdriver or cold chisel between the flange and the knuckle too.

If you're going to beat it with a regular hammer, at least put a piece of wood between the hammer face and the spindle.

I use the wooden handle of my BFH to 'release' the spindles grip on the knuckle.
That should clean up fine.

The last time I pulled a spindle I put some spindle nuts on the end and smacked them a few times with a BFH. Once a space started to show I used a wide chisel in one side of the space and tapped with a BFH on the opposite side, then switched the chizel to the other side and did it again. Over and over again. fairly soon the spindle slid right off with absolutely no damage or marks. Even the nuts were undamaged. As Lumpy said, this is easy enough to take care of.

They do have a tool that threads onto the spindle you attach to a slid hammer.

The damage from a BFH makes total sense. The spindle nut was also badly abused in attempt to release and tighten it. I found it only finger tight!!!

Cool tool, great if you've got one, didn't have one, didn't want to wait, wouldn't have even if I knew the tool existed anyway. I was told how to do the job and it worked flawlessly. Of course it isn't wise to simply beat on things with a BFH. A little style goes a long way, tap, tap ... tap, tap ..... wiggle, wiggle, DONE. I don't even have a slide hammer.
