Suspension hangers

I have a 16 kz Durango fifth wheel
The leaf spring hangers on the drivers side are straight and square.
The 3 hangers on the passenger side are not square.
All 3 brackets look the same. The metal is straight with no signs of bent metal or a cracked weld. The factory square tubing that the hangers are welded to are also straight and level.

The trailer hasn't been curbed and hasn't hit any potholes. I'm careful when turning so I don't put too much stress on the axles. The trailer scaled under the max weight

My opinion is that these hangers weren't installed right from the factory.
If the 3 hangers on the one side are bent from road force, wouldn't the other side be bent as well? Tire wear is fine.

Opinions?

A couple of weeks went by and they couldn't get an answer from Keystone on what they would do. With 3000 mi. on the 5R the shop mngr. said they took it all apart and replaced the worn out bushings and straightened the brackets then installed the correct track sys. I picked up the 5R and will use it through the summer and a 2500 mi. trip in September and if the brackets bend, the dealer said they would back it even though it would be out of warranty. We'll see how it goes!




I instaled Correct Tract on my to lift the E, works well and I alinged the new 7K axles. I have CT to gain 2ins cause new truck bed are deeper.

This is what I did about 6 years ago, replaced hangers and new springs and made the cross brace.I bent mine I think by backing into right angle spaces.

IMO, those are a manufacturing "defect", as they're all about the same angle. Likely 2 different welders, one on each side, welded them up. Almost looks as if the hangars just weren't centered on top of the frame and the one side is riding up on the radius where the strap was broken on a press, which is what's causing the angle. Sloppy, sloppy, sloppy...but do we expect much better from LCI?

On my Heartland Sundance all the hangers are leaning inward. Once I noticed, I have watched very closely and 6 yrs have gone by with no issues.

Afterward I have checked lots of trailers and found that it's not that uncommon. The only reason I can see for that happening from the factory is that the brackets on the axles being slightly off from the width of the frame of the trailer so they just bend them to attach and let it go.

It's definately not right but probably wont hurt anything.

Our 5th wheel is a 1994 and at the time not many RV'ers had the axles flipped (truck beds were much lower then). I asked the factory to flip the axles after I discovered the tail dragged badly when turning onto our street (large dip). The factory flipped the axles and within a couple of trips I noticed the axles had shifted towards the passenger side by a couple of inches.

Back to the factory and they realigned everything and then welded cross bars from one side of the frame to the other. These were welded at the bottom of the I-beam frame to keep it from bending.

No problem since...

Thx for the information. I checked the frame and it looks good. There are supports welded on an angle on the bottom of the I beam frame

^^^ That's it^^^^
Look for faint cracks in the paint. There have been posts where hangers and chunks of frame are broken off.

Now is a good time to add wet bolts. They probably won't do any frame modifications under warranty but some day you may need to add metal for reinforcement depending on frame design

I was looking to buy an insurance salvage tt years back. It had minor damage on the bottom edge of the drivers side and broke the sewer pipe off. The drivers side hangers were bent worse than that yet the passenger far less. It just seemed that if everything was getting slammed on one side more of that force would transfer to the other side as well.

It's at my dealer now as the trailer still has warranty. I just wanted feedback in case they try and blame me!!!

Looks like a sloppy job from the frame manufacture, I'd have them redone.
