Are these axles bad?

When I jack up the brake drum from the bottom, I get 3/4" movement then the trailer lifts up.

RD,

It appears you do have some down angle on the arms, a pic from the inside would help. As you load the axles you would like to have 3-4in of movement, not past the horizontal.

The rubber in your axle has aged and become hard. They therefore will not flex when they come to a bump in the road and all the force will be directly transmitted to the body of the trailer. This is bad. Your axles are shot and no one is in the business of fixing them. You should plan on replacing them, if you intend to travel very much.

Roger, put a jack under a brake drum and measure how far you can raise it before the trailer raises off the jack stand. A bad axle is 1" a good axle will have 3-4" at least.

Look at the bright side of things, after spending the cash for the axles you'll save tons of time not having to pick everything up off the floor after going down the road for more than five miles!

Remember in life, you can always make more money but you can't make more time.

Oh, and if you're going way of Avonton, Ontario I know a guy that can put them on for you.

Enjoy,

If you get the pressure point from the jack on the "mouth of the bell" of the drum you could very easily crack it or make it out-of-round.

A much better approach would be to measure from ground to wheel well molding with AS sitting on ground with tires in place.

Jack up as Bob shows, until tire(s) just leave the ground.

Measure from ground to wheel well opening.

Subtract first number from second and you have "axle drop" figure.

They are about as hard as they get. Don't worry about the drums, you get new ones with the new axles.

I agree, drums are being replaced with axles.

I am going to strongly consider going to disk brakes when I replace my axels.

So you do...but the other one had your shock in the pic, and could keep me from installing my shocks upside down. Or I suppose I could take my own pic...:-)

I think I also would consider disc brakes whenever I have to do the axle thing. But need to do a lot more reading first..

Chuck,

Has AS resumed offering the disk option on the new units?

I was also considering the up-grade, but decided to wait.

Guess it's better to have less efficient drums, than non-existant disks.

A reliable disk system would definitely be worthwhile and is most likely available, with a little more research, but with our towing habits/routine I haven't rationalized the cost factor yet.

"if it ain't broke...fix it 'til it is"

Disc brake options are certainly available on replacement axles. Although they are more expensive than electric drum brakes, you will also need an "electric over hydraulic" actuator. This adds to the cost & complexity of the installation. Keep in mind that modern 12" electric drum brakes are used on 5000 lb axles & on 7000 lb axles, so they really are "good bang for the buck".
Thanks,
Colin
