Suspension mod.

I he's just removed the axles and placed them under the springs instead of above then it is a fairly simple matter to remove them and put them back the way they were.

If the axles are straight through, this is probably what he's done. If they are stepped then sometimes they rotate the axles to reduce the amount of lift when they undersling them. This can cause you a problem if you put them back because the main beam will have a slight bend in it to give the wheels a small amount of camber and if he had it done correctly they would have had to reverse the slight bend to get the camber right.

Check the toe-in of the wheels. Most axles are not straight and in fact Al-.Kko claim to put some toe-in supposedly to provide stability for the towed vehicle. I reckon it is because they cannot weld the stub axes dead straight (due to contraction as the weld cools). I had a brand new Jayco van which whore out a set of tyres in 18000 km and despite attempts to fix the problem wore out 3 sets of tyres before finally Al-Ko (the axle manufacturer) replaced the axle on my van for free (including freight)' I have since seen lots of vans with tyres worn on the inner edge of the tread.

If you rotate you axle, what was once toe-in will now be toe-out or vice versa. Check your tyre wear before you change over as well.

If you reverse the axles as in roll them 180 deg the brakes will be backwards as well You would need to remove the springs and replace them under the axle and make sure it has locating pins etc

Paul, I'm not sure where you're located - but a bloke near my workshop in Bayswater seems to do a fair bit of minor caravan and trailer repair, and would probably give you an estimate of the cost.

He trades as "Gas Smart" but I don't think he does any gas work nowadays, due to LPG being a dead loss economically.
He appears to be just a one-man band with a bit of a junk-strewn factory setup, but he seems to be capable enough, and I've seen him doing a fair few caravan and trailer axle repairs.
His phone number is 0405 668 804 and he's at 21 Wotton St Bayswater.

Cheers, Ron.

Any particular reason why you want to put it back to standard ?

Put the van on chassis stands, undo the springs and put them back under the axle and bolt back up. Probably take an hour all up !!

Why bother ?

thanks for the replys.
doing it myself is an option but only have myself to do it
and most things like this are difficult on your own.
I'm really after the experiences of people who have had it done by a pro.
