D70HD axle flange bolts

[SgtHighway]

So I got a Dana 70 HD out of a scrapyard, rusty but all there, one side seized up the other side spinning freely. only issue is the axle flange bolts. Frozen in there really good. Took a breaker bar, a 6 foot pipe, and my whole body weight to get em to move..... on the seized side....now I'm on to the spinning side and I can't apply any torque without the drum breaking free from the ground/chocks and just spinning.

Any long timer wrenchers have any tips for stopping it up? Bar through wheel studs? Jam something in diff? Bolt a steel plate to pinion?

I've used a 3 foot long pipe wrench on the driveshaft yoke to hold the axles from turning when tightening a pinion nut--that should work for you,since the gears will help make it harder for the axles to turn the pinion...but if its not a posi,the other axle might just spin instead...you may have to put a bar thru the wheel studs or use an old rim with a few holes torched in it to let the bar poke thru it to hold it still...an air impact gun would be a help here too..

I usually put a prybar through the wheel studs and then breaker bar on the bolts. put the handle of the prybar on the ground, or hold it. Then crank on the breaker bar, be it with muscle or body weight. I would put it on the ground to make sure it doesn't jump off a jack stand. That's always the worst.

thanks dude!

It's not posi, but the other end is seized up and not moving without a rebuild. Pipe wrench sounds like a good bet, as does finding a ****ty rim. At that point I'd just torch a flat across one side of the rim I think.

xenomarine, yeah its on the ground, there's NO way I would have gotten the other side off with it in the air.

How much does it take to end up bending those wheel studs?

 

[xenomarine]

Way more than you're going to be able to produce with a regular breaker bar. The closer to the wheel mounting surface the breaker bar is, the better. Less leverage on the studs, and if the threads are going to get damaged, it'll be mostly in a spot where the lug nuts won't reach. Mostly. If you're worried, wrap them in cardboard or electrical tape to give it some sort of cushion. I'd probably just put the breaker bar between the studs, rotate the axle so the handle is on the ground, then put the breaker bar on and stomp on it. Usually the shock of such an action will get them to break free. Failing that, get a big section of pipe for leverage.

yeah, I got the other side off with just a **** load of pulling and jumping so I'm confident I can get this one off if I can fix the hubs rotation

Thanks again guys
