jayco suspension changes

Some one else asked this a few days ago so go back thru the threads and u will find the answer.
Probably will need a certificate after doing it Cost ? Mine was $500 for a recertifiaction to uprate GVM.

Hi Grant, the only thing I would query is whether the spring and shakles

thanks David,

I am thinking of moving to under the spring and changing back after trip, but you raised a good point

Grant

Hi Grant,
It may not be that easy to just put it underneath and then put it back after the trip. There are locating pins/bolts on the springs with mating plates, possibly welded to the axle, which may need to be relocated and rewelded in order to properly locate and secure your axle in its new location. If you have shockers, that may cause further issues as they may not be long enough.
Can be done, but make sure the axle is properly and solidly located.
Cheers
Gerry

Hi Grant,

It was me that asked a week or so ago. I did the 'under-sling' my self on my 2002 Hawk. I achieved a 110mm lift. I have a 5 leaf spring set-up.
Procedure;
Jack one side of the van up (make safe with stands etc.)
Remove wheel, u-bolts and spring hanger bolt
Drop spring off body - away from the axle
Invert centre leaf bolt
Grind off locating lug from axle, re-weld on top of axle
Refit spring over the top of the axle
Reassemble
Repeat on other side
Have a beer and admire the room underneath.

I my case, no adjustments were necessary to the hand-brake cable or the electric brake wiring. The side door step is a little high, but you get used to it. Annex wont fit either. Jockey wheel may need adjustments (if a welded on swivel type).

Lots have done it. Lots more will. Whats the drama. Get on with it, and the knockers get over it. There are some people who never get or have never got of theire backsides and done anything who have a lot to say.

On some vans it's a good mod, on some vans it's not.

One thing you may also need to consider is the change in hitch height in relation to your ball.

I put longer leaves in with gas shocks on my jayco and the van is just awesome even over very rough roads.
I think they were holden springs from memory

I have a n old Jayco Dove (1978 model ) and had the springs put over the axle about five years ago, with no problems. Put 14" light truck tyres on ( originals were 13" )and haven't looked back. The van rides better, feels better and looks better. Don't have an annexe so no worries there. A couple of extra wooden blocks in the bag to put under the legs etc, and a box near the front step for that extra hoist up !! SWMBO and I are mid sixties, so need a bit of help. Had it done specifically for a 6 month trip to WA incl. Kimberley. Made the G.R.Rd. a lot more negotiable. Go for it.

Hi
i did similar as perthburts did to my finch only i add shocks as well.
no problems 5 years on and many trips and provide good ride height,in the process of swapping brake hubs to 6 stud to allow fitting of 15" wheels 215 x 15 trye
thanks Russell

Grant,

A mate bought a used eagle from his local coromal shop. They moved the axel for him. They didnt have a problem doing it.
But the height change affected his annex and skirt.

good luck
