1989 Layton TT, Axle flip? What brand axles?

Hey y'all,

I know this topic has been covered a bunch and I did read some of threads out there on this topic.

My recently acquired 89' Layton seems to sit very low to the ground to me. Although I have not measured, I'm sure it has less than 1' of clearance from the frame to the pavement, and of course the black water tank and piping in the rear extends below the frame a few inches.

A prior owner must have had problems because there are steel roller wheels installed on the rear frame of this camper and on my trip back home, when backing into my driveway, my wife said the rollers did hit the asphalt on the driveway. I do not believe they took much weight thankfully, but I have read various posts in the past that the rear rollers are NOT good, because when they hit they can twist the trailer frame.

The prior owner gave me his hitch with the camper, but my Expy sits higher than his Suburbans did, so the trailer was a little "nose high" coming home, which I know contributes to lower in the rear and is excerbating the problem.

I priced a few "extended drop" shanks for my reese hitch and they are all $100+ and even if I go that route, there's no guarantee I won't still hit backing into my driveway.

So, I've been thinking about doing an axle flip (relocating the springs from below the axle to above the axle) which will increase my ground clearance I would guess about 4-5" or so and likely eliminate the clearance issues and allow me to keep my current hitch shank.

I'm looking for pros and cons to doing this. I do have a mechanical background and have replaced leaf springs on a variety of vehicles in the past so I believe I can handle this job myself. I also have an torch, which I have come to find is essental when working on older vehciles (rusted bolts/nuts, ETC).

I would do the job one side at a time and leave the opposite side of the trailer's tires on the ground and keep it hooked up to my truck for additional stability when I'm jacking it up.

Does anyone know what brand/type axles I have on my camper and if there is a "kit" for this job? Currently the spring perch is on the bottom of the axle so I think that would have to be changed, unless the kits give you a new one, but then I'd be concerned that I get it on the right spot on the axle or the trailer will not run straight.

Do they make "helper springs" for TT's that would give me another inch or two of clearance? From my perspective I either have to spend the money for an extended drop so I can get sitting level and then hope I don't still have clearance problems or just do the axle flip.

EDIT: also, how do I determing if I have a 2-3/8" or 3" axles?

Any help or suggestions would be very much appreciated.

Sincerely,
Greg
  • Ok, thanks - Unfortunately, it's been raining like all get out in my area for the past 2-3 days straight so I have not been able to work on my rig much at all, unfortunately. I'm hoping it dries out some by sunday so I can get under it, see what I have and get it jacked and get this project started.

    I do have a pair of dial calipers that I think will open up at least 3-4" so I will use those to get an exact measurement and then go from there.

    I decided I will hitch up to my truck, then jack each side a little at a time, placing cribbing/supports and jack stands as I go up until I get it where I want it, then once I have it at the final height and blocked securly, I'll lower the trailer crank-down stabilizers just for extra security. I figure that will make it safe to work under.

    One other question, if I measure and confirm I have 2-1/2" diameter axles, would the 2-3/8" re-location kit work?

    Thanks again for all the helpful thoughts and replies I appreciate everyone taking the time to offer suggestions and thoughts.

    Yes. 2-3/8 kit will work.

    To learn more about under/over kits from Dexter, surf: - Click Here -

    During my re-position axle "under" the leaf springs, I didn't buy the formal kits. I simply bought the individual parts from my local Trailer parts store, bolted together, then towed my trailer to my local welding shop. The welder guy simply crawled under my raised TT, applied some welds on the bolted down axle perches, and all is now good.

    This trick might work for you as well...
  • I completed the job yesterday.

    All went fairly well...as always when I do something new for the first time there is a learning curve and some things I would do differently if I were to do it again...but by the time I got to the second axle I got it done much quicker. I was able to retain my original spring eye hardware. I could have put new shackles and bushings in it...but for the 4 times per year it will see the road it's good.

    Feels good to have done it and hopefully put my clearance issues behind me...pretty good for only having the camper for a week so far I think.

    Thanks to all for all the great help....we campers truly are a kind and helpful bunch. :-)

  • .

    Yes, each mod is a learning experience...

    Glad the job is done and the results are pleasing. Way to go.

    For my RVs, I often plan for 3-4 mods each year. Little things from towel holders, to Surge Protectors, to protective steel wire mesh fence around its Hot Water tank, to much larger jobs. If you also pace yourself, what is your RV's next mod?

    Again... Way to go on this mod.
  • Hi spike,

    Thanks. I have to buy 4 new tires for it and I want to get a spare as well. So I didnt get it off the blocks yesterday but I can already tell I will gain several inches in height. Good stuff! While I was at it yesterday and already very dirty from the axle work I went ahead and wire brushed the entire frame and cross supports...I was going to do this next year...but since I already have it up high....I figured now is the time....I'll be panting it today...
