Ford 9" Axle Issues

I was having issues with my axle seals leaking and I was pulling the axles out to have bigger wheel studs put in so I figured this is the perfect time to ask around and see what you guys think. Below is a picture with the axle bottomed out into the spool. As you can see there is a good 1/4"-3/8" gap. Is this normal?

Thanks
Shane

Not normal and looks like your plates are now bent. Do you have stock axles or aftermarket? Where do your brakes bolt/mount on? Do the splines bottom out on the spool or do the axles touch in the middle? If you are running a spool, I am assuming you have aftermarket axles - if not, that could lead to a potential dangerous situation.

There currently are no brakes on it. I got a weld on kit from ckperformance. They are stock axles that were cut down. Total rear end length from side to side is about 36". Do you think the person that did this before me possibly got the axles too long?

Looks like they might be too long. What is bottoming out? The splines or axles touching? If the axles are touching, is there more spline left to go into the spool? If so, you may just be able to trim some off the ends.

Pull axles, put grease on splines and end of axle. Re install and remove. Grease will show where its touching.

spool

That isn't supposed to look like that. I'm betting that with the spool your axles are too long. Yes, the grease idea will be helpful to determine where they are seating in there. I would invest in some aftermarket axles and get some fresh seals in there. You may be running into some real issues if you dont fix this problem corrctly

Well the first problem that you have is that there are no brake backing plates installed. The housing ends are designed so that the bearings stick out about 1/8 inch, or the thickness of the brake backing plates, when the bearings are bottomed out in the housing ends. That way when you bolt the bearing retainer on it will fit flush against the bearing and backing plate and hold the bearing and axle in place. If you are not going to use drum brakes then you are going to have to make spacers to make up the difference for the backing plates.

Also check to see if the bearing retainer rings are hitting the axle seals. I've seen that a few times.

You know that the weld on brake bracket is going to cause the axle tube to warp some, right?

Some stock axles run out of spline before the axle is fully installed.
Depends on the design of the spool and the particular axle, especially if someone has been mixing and matching axles in a narrowed housing.

It did have drum brakes so I guess I can take the old backing plates and just trim it so that the old piece just acts as a little spacer. Ill start there and see if it clears up the gap I have.

The kit I got did mention that you have to weld in small increments, alternate from driver to passenger side, and take time between welding to let cool to help minimize rear end distortion.

I will make sure my alignment bar is in the rear end while I weld the brakes on too to help prevent it from distorting at all. Thanks for the input everyone. I will cut down the backing plates this weekend and see if they fix the issue.

If i had the rear out, i'd cut the ends off, weld the brackets on, then weld the ends back on with the alignment bar in place. The truer you can make it, the longer your tires will last. I run drag radials on the street, i want my tires to last as long as possible

You can get the axle tubes straight again by drawing them back with a tourch and water. I've had to do this several times when welding was done on a housing that already had ends installed.

D@mn, ya'll are scaring me now. I have a set of CAChassisworks triangulated 4-link brackets to weld on a completed axle. How can I check for trueness after welding it? Can I ASSume putting the axle in and checking for rolling resistance would be enough?

I'd run a tape down thru the tubes and check the measurements for the axles.
