Boat, engines and trailer about 12-14,000 pounds. If you're in Victorville then you're on your own.....
We live in Victorville now. We own land in Des Arc and will be moving there in the near future. Was thinking about taking the trailer out there for a family reunion and wanted to resolve the tire issues first. Thanks tho!

The first tire is the other side. The right rear. That onehas 8000miles and is wearing also just not as bad. The second is the one thats wearing bad. The third is the other half of the one thats wearing bad, the left rear. Its odd that its half bald and half somewhat. Have an appointment on Saturday at trailer shop to look at. Dont know why this trlr has 2 5200lb axles when it weighs 10300lbs empty.

Yeah you got a problem.
If you subtract 2,500 pounds of kingpin weight from the 10,000 empty weight, you are OK.

Keystone's math is frugal, isn't it? The axles they use are likely 2.5" which bend easily from those hard turns. We had nearly the same issue with both rear tires wearing poorly, turned out our rear 2.5", 3500lb axle was bent(trailer is 6,500lbs dry and a shade over 7K loaded). Swapping out to Dexter 3" axles (same tube as 6,000lb but reusing our spindles), leaf springs with an extra leaf and 'D' rated tires not only made it tow MUCH more stable, but gave it some breathing room. We'll always adhere to maximums on the placard (just like the truck capacities).

I am surprised we don't see more of this with parts chosen to live so close to maximum...

I'm usually not in the position of defending Keystone, but they are just buying parts from vendors and screwing it all together. Dexter is selling axles that they say have a 5200# capacity. I doubt if Keystone is doing much research on how/why the axles bend. Dexter should be all over the computer modeling of side forces and failures. "Should be" being key. Metallurgy and structural strength aren't new issues. Keystone should be doing due diligence when selecting vendors, but the buck stops with Dexter.
Just me, but I wouldn't be putting beam axles on any trailer. From my experience the torsion bar suspension is superior. Of course if I needed a 5,000# axle, I would likely use a 7,500#.
My 5th has a 12,500 GWR with 5,200# axles. Just "ballparking" the numbers: if I run with 3,000# hitch weight, that leaves me 9,500# on the axles. Dexter rates the axles at 5,200# each. That has almost 1,000# of spare capacity between 2 axles.

To be accurate the tongue weight is 1700lbs which still puts me to close the the max load on the axles with bouncing around and all. Anyways got a quote from shop today to swich to a 6000lb axle.....$450. Not to bad if you ask me.

That's not bad at all. I'd do them both and be done with it. You'll still need to have them cambered, because they are delivered straight and will cause inside tread wear if not cambered. My 6000 replacement was anyway. Been there done that on my Montana.

Yeah, I'd jump on that. I assume that is a complete deal. ..spindles included. Be sure the hub is the same as yours, bolt pattern...number of studs. But, it's not that big a job to have the axle shop weld different spindles on.

Gearhead just brought up a good point about the spindles and wheels. The 6000# axles come equipped with 8 lug (8 on 6.5") wheels when factory installed on new trailers. All the 5200's I've seen come with 6 on 5.5".

The shop owner was very specific that 7k axles were 8 lug. The 6k axles that he was gonna put on were 6 lug. He s utilizing the same drums. Id do both now but rest of my money tied up in a boat motor being rebuilt. But its on schedule as soon as I can.

I see you are planning on changing the axles, but did you get a definite answer as to what was causing the wear?

Nope! Dont know how to prove what exactly is wrong. My brother and I looked and see nothing wrong. All I know is the trailer shop says the axle is bent and everyone seems to think so on the forum. Gotta do something.

Wow, I just used the search function, and an active thread came up, with similar issues, so I hope it's ok to dive in with an issue I have:

My 2013 hideout TT, 29BHS, 7K dry, 9k loaded has 6000 total miles on the original tires and suspension. Have not rotated tires or altered anything. Towing with same set up, truck, wt dist, hitch etc. Two days ago we got back from a 300 mile round trip and looked at the tires closely. Was shocked to see steel radials on the insides of BOTH rear tires. Outside of rear tires, look fine, lots of tread, inside completely gone and scary. Front tires look fine, no abnomal wear that I could see. I just noticed this yesterday while dumping tanks on the way to store for a month, so I don't have a picture right now. I had taken a look in the spring and saw the insides were wearing, but didn't think they were that bad, and shame on me for not inspecting closer this summer. I do keep psi at 65.

I guess having that wear exclusively on the inside kept my quick visual inspections from noticing it. Based on what I'm reading here and phone calls to two keystone dealers(neither local) for input, I could be looking at:

*axle lost camber
*axle out of alignment
*bushings
*issues in towing with nose up or down (i tow it quite level and don't suspect this)

In the end, I will be taking it somewhere, as any repair like this is over my head. I'm hesitant to call the closest RV dealer (not a keystone dealer and I didn't buy from them), because I don't hear the greatest of praise from them. If I do go there, I'd at least like to be educated in what I'm dealing with by hearing if anyone has had similar experiences.

Thanks for any input.

I wouldn't even bother going to a dealer. If I were you, I'd just put 2 new tires on and then take it somewhere that does trailer wheel alignments and have one done. I had the same issues on my 5er. I put FOUR new GOOD (Maxxis) tires on it, and took it to a heavy duty truck and trailer shop and had the alignment done. Found it was WAY out. Haven't had any issues since. Knock on wood.

Good advice. I agree. It sounds like most RV dealers/service centers are more able to service RV specific items and the one dealer I called even said they don't do alignments. This is a trailer axle issue that I would think any trailer/truck service shop could handle and do a better job at without ripping me off (well maybe).

Talking

Took the trlr to an old school alignment shop. $100 an axle. $200 total. Guy said they were way off. Also put two new dynatrails on the rear. $215 installed. Think she s all good.
