Inverting axle on a Jayco Expanda

I am familiar with two terms - rolling an axle and - underslinging an axle. Rolling an axle essentially means just turning/twisting the axle 180 degrees. With an Alco drop axle, as used in most Jaycos, this is to be avoided because the stub axles are set up with a slight camber to allow for the applied weight. once 'rolled' the camber is 'the other way' to that designed, leading to accelerated tyre wear.
To 'undersling' the axle is to remove the axle from its traditional position above the spring cluster and relocate it under the spring cluster, without rotation. This will give an increased clearance without interfering with camber angle. This can be done by the average home handyman who can weld. However, I believe that any such mod these days has to have an engineer's certificate to satisfy ADRs and insurance requirements. Hope this helps.

Thanks Pud for your info. I see you're heading in the same direction as us towards the end of June - might see you on the bitumen somewhere. Cheers Rachael

Yes, and then there's the matter of the towbar tongue: the draw bar may be too high for the towbar, and require a new tongue to get a reasonable line up. Otherwise, you'll have a van with a nose down attitude.

Axle under leaf should be easier on the u-bolts for starters so instances of breaking them should be reduced.

Besides, there are plenty of vehicles that have axle under leaf as standard.

I agree about the load on the u bolts,, it does have that in its favour,,, yes i know they are standard on some vehicles.. Michael

If you just roll it over your brakes linkages will be facing the rear.

Think things out first

We are very content with what we've got it's just that nothing is ever exactly perfect & I thought I'd ask a question about improving it & getting some advice. Amazingly enough people often do this very same thing on the forum. Good luck with buying your Expanda, hopefully you will choose exactly the right product for you after you have received advice from others on this forum, including me.
