Hi Guys
I need to lower the rear of my Hijet and i`ve seen people remove the top leaf and turn it over and re-fit it? Also seen people de-camber springs with a homemade jig and a bottle jack
Will that work? Also how do i take the multi leafsprings apart without losng my fingers?
Cheers Adrian

Before turning the leaf over I'd look at getting them de-cambered as a better solution. You should be able to get a good 2-3" drop from that.
If wanting to take the springs apart, once they are off the vehicle they aren't under tension so there is no risk of injury or loss of finger unless you start using one of them as an axe or something equally daft (I'm now giving myself some ideas for the next play weekend ;D )
Basically, get them off the car and remove the leaf brackets & pins and it'll all come apart.

I think Johnny69 did one for his Pop. There's a tread on here somewhere.

Hi My mates got a 12tonne pipe bender so we can decamber the leaves, But how do you lose the camber without the spring length (eye to eye) increasing?

simple answer- you cant. ive made a press to do leaf springs, detailed HEREthe only way to compensate for the spring being longer without getting new, shorter main leafs made up is to move the main chassis mount for the shackle backwards a bit. as its essentially just a bit of tube welded into the chassi rail, its not too hard to do. ive also seen it where people go one step further and offset the holes drilled in the axle spring pad a little to re-centre the wheel in the arch- its ok if done within reason, but anything more than an inch is pushing your luck really. ive never seen it need to be moved more than that though anyway.

You weren't to know this, but the car in question has spring over axle set-up so lowering blocks will actually raise the vehicle, not lower it. Doing a spring under axle conversion is possible but I think it might then be a bit too low for what the OP wants? Decambering would be the first port of call IMHO then go from there.

youre probly right bruce, flipping an axle under to axle over usually equates to 4.5-5" of drop, depending on how thick your spring pack is, as most axles are around 3" diameter on the tubes. thats a fair old drop, and youll usually have trouble getting that much drop at the front end (to get it to sit level) without major surgery.
you may be doing it to a vehicle with a back end thats already a good bit higher (like a lot of commercials), then its quite beneficial. for example, after i axle flipped my escort van, which gave 4.5" of drop, i only had to drop the front end 3" for it to sit level.
as you say, decambering is a much more 'tuneable' drop.

I was wondering this TBH, As he hadnt offered that as an option i presumed it was already slug under. with out seeing the full axle its hard to know. How long is the spring eye to eye? Could another leaf spring be used? if you can find the dimensions and donmt mind trwaling a breakers yard.

Just so happens I'm considering offering an exchange service on properly Decambered Hijet Springs. I was thinking something like £100 (and your old springs). To make life easier £150, I send out your decambered springs and then when you send your old ones to me I refund £50, that way your hijet isn't off the road. Not sure if thats reasonable or not. I'm having the first set done next week, a 2.5" drop + the drop you gain from having the load leaf removed. Once fitted i'll see if there's any problems and consider whether its worth offering the service.
In the mean time you get a better ride and a small drop by taking out the overload leaf (second from bottom from memory) mines LPG so I had to remove the battery box to get to the rear o/s hanger. Can't remember if you need to do this or not if its not LPG. Its pretty easy getting the springs off. Then just undo the bolt holding the pack together and remove the leaf. I had a local metal shop knock up a spacer with a hole in the thickness of the removed spring. They cost £6.
