Default Was there an axle upgrade on the 04 M380?

Good to have you on the forum Erik! We just need to get you into a Wanderlodge so that you can enjoy the fruits of your labor...they are truly great coaches!

I have a question regarding the front axle on my 04 M380. The tag above the windshield indicates that the front axle is rated at 14,600. When looking at the actual tag on the front axle it indicates that it is 16,000.

Was there an upgrade to the 16,000 axle or is there some other limiting factor that keeps the rating at 14,600.

When I was asked to take over the chassis & axles, I wanted to commonize several assemblies, most notably the axles.

The original M380 axle was indeed rated at 14,600# but with several minor modifications to the support structure, we were able to upgrade it to the same rating as all other axles - 16,000#. If the actual data plate on the axle says 16,000#, check your wheels and tires to make sure they are rated above 16,000# (8,000# each). I'm not sure of the first body number that has all components rated at 16K (normally stocks of older parts would be used prior to changes coming on line), but with some careful checking of the axles, wheels & tires, you can determine what your true rating is.

Hope this helps,

Erik

Went out and checked the wheels, max load is 7,300 lbs per wheel x 2 = 14,600. So there’s the 14,600 rating for the front axle tag in the overhead. Tires are rated at 7,390 max load; plate on front axle is 16,000 lbs.

Thanks for helping me clear that up!

So if you changed your wheels, and tires to match the axle, your front axle would be good to 16,000 lb. Am I understanding that correctly?

That’s the way it looks to me Peter…maybe Erik will chime in to confirm!

Likely worth the cost, I would think to gain 1400# capacity on the front.
By the way, Congrats on the new rig.

My chassis number is 00141. I’m sure you must have the 16,000 lb. axle as well! You can check the axle tag without getting under the bus, you just need a flashlight and a good set of eyes.

If you look from the left wheel well, forward of the tire, you can see the silver tag on the axle with all the info.

Yes, by changing the tires & wheels, you would upgrade your rating.

If memory serves, the original tire was a 12R X 22.5 (imp). The upgrade would be to a 315 X 22.5 (met). Please bear in mind that the wheels would need to be changed as well.
