Bent Axle?

memgrove2000 · 07-03-2009, 02:28 PM

We replaced the axles on our 72 31 foot Sov. And now it is "eating" the left rear tire! (noticed before the trip last weekend and while changing the FLAT in a parking lot) The tires were purchased new in the spring of 08 and balanced soon after. ( still cant believe that argument with the sales person " trailer tires don't need to be balanced") Any way after replacing the axles with "OEM" equipment now it is wearing tires badly! I am curious as what to expect to pay for an alignment? I have not had to have a trailer done before and have not even started looking for a place to do it yet. I just would like to know a ball park figure before I go. Has any one ever been shipped "out of alignment" axles may be I should call Inland and see what they think? (could not hurt right) Maybe Monday after the holiday.

Thanks Mike

Mike.

Prior to being painted, all the Henschen axles are aligned automatically.

Freight lines can sometimes do strange things to most anything. There is no real way to tell.

Your not that far from JC.

I would suggest that you make an appointment with them to check the axles.

Should there be a defect of anykind, Henschen is around the corner from Airstream, and would quickly take care of the problem.

While your at it, have the wheels checked as well, to make sure their within specs.

Please keep me posted.

Mike you do not describe the tire wear, nor is there a pic to look at. Different types of issues cause different wear patterns.

Possible issues;
Out of balance tire/wheel asembly
Bent wheel rim(s)
Improper installation of the axle
Axle assembly bent or not inline fom side to side
Multiple axles not lined up with each other

How the tire meets the road and reacts to the road irregularities will make a difference wear.

Hello Andy,
I did not expect you to be here over the holiday weekend. But thanks all the same. Don't take this the wrong way But Jackson center IS a long way from here when you are in my shoes. 185 miles one way, 3+ hours( drive time not the issue) , possible flat tire again, NO JOB TO PAY FOR IT ANY WAY. So Yes Jackson Center is A bit far for me right now. ( I know it is not your fault I am just saying). I am looking for a local shop that does trailer alignments (just had not started before I posted the how much to expect to pay question). Today I see in the phone book and Internet there are several options in the area (just not open today).

Why couldn't I have them checked and fixed locally. I do live in the RV capital of the world, I also know that airstreams ARE different. But we are talking about tire and axle alignment. Don't the dura torque type axles align the same? ( all tires must be in alignment on sob's too)

If there were a production problem wouldn't Henschen honor warranty repairs any where? ( they put those axles on everything not just airstreams) If they were found defective here would they pay for the repair.

You might not remember but We did have a shipping damage problem with ours ( the factory had to send us two new grease caps) But I would think that would not have affected the alignment of an axle.

I am just trying to keep all of my options open at this point.

Thanks Mike
Happy Fourth!

Action, Darn fine Idea! I think I will run over to the AS and get the Flat tire out of the carrier and shoot some pictures. Might take along a 8 foot bulb too. thanks for the idea Mike

memgrove2000 · 07-04-2009, 12:28 PM

Here are some tire pictures of the flat one. There was a rock in it that punctured it but look at the tread ware pattern.

The bulb does not touch the front of EITHER tire, I know this is not a proper tool but it should give us a generall idea.

Yep, bent or out of line axel I think.. Our friends SOB has the same problem, Wasn't cost effective from them to get them fixed. Cost more than the trailer was worth. They figured it was cheaper to buy a new tire when needed.

Take some string and do a measurement. What follows will check the toe in measurement.

Measure the string from the front outer edge of the left and right side. Then measure the same tires on the rear outer edge. This is a bit rough however the front of the tires may be ever so slightly (1/8") toed in or pointed in from the rear of the same tires.

Do this for both axle set. The rear axle set should be the same as the front ale set. If not then you are looking for a condition that may be a bent axle.

The above does not check for misaligned axle as in one that was mis-installed, or out of balance tire/wheels.

The wear s that on the insdie of the tire or outside?

Do you know what a feathered edge on the tires? If so that is an indication of incorrect toe in.

The pics above appear to be a camber issue. If that wear is consistant all around the tire then it rules out a bent rim. A camber issue for this type of axle can only be repaired with an adjustment - this assumes the axle is installed and centered correctly on the trailer.

Worn out on the outside, Picture on the top right shows a spot that is worse than the rest of the tire ( the guy that balanced the tires had to use a LOT of weight to get it "close")

We bolted the axles in the same spot as the originals. But did no other checks as I was under the impression with these axles they would be a direct replacement.

Still would like to know an Aprox price for an alighment?

I suggest you try to align it first yourself. Take the tires off and tie a stiff string to the jack. Pull it back and see if the hub centers are different. You might then loosen the bolts and center the axle. Even a slight shift could be a huge difference. This is exactly what those shops will do.

I'm wondering if you all are not reading more into an alignment problem. If you look at a good (new) axle you will see an apparent bend in it. Thats the way its built and supposed to be that way. I hope your not changing an axle just because you see a slight curvature there.
