Spring over Axle Conversion

[jakwoo39]

got the other half of the spring mounts made today,
i got 2 bits of 50mm bar and bored a hole through the same size as the bushes, then got some rhs and drilled a 50mm hole through it then cut it in half and welded the 50mm bar into the 2 halves of rhs
and they come up like this


and also put new seals and boots in the front calipers and gave them a paint and some new pads so teyr like new

[jakwoo39]

just got round to doing a few little things today, had to get a new seal for the drivers front brake caliper then got it back together
after that i went and bought 2 new CV joints and put those onto the front axle


then machined the rear axle where they bolt to the hub and polished the axle seal surface

also my rims and tyres are back at the tyre shop to swap the rims out to a -19 offset to get me some more clearance between the inside of the tyre and the chassis rail, i originally had +12 offset so this will space them out nicely

[jakwoo39]

its been pretty slow progress the last few weeks have mostly been waiting on parts.
the tires are still at the tire shop awaiting their new rims, im getting -19 off set instead of +12 so they will stick out a fair bit more and save me having to use wheel spacers

and i have ordered the new shocks, i went for the rancho rs5000 as they are quite hard and should counteract the body roll i am expecting
but they had a mix up at 4wd bits and sent me 4 rear shocks so im still waiting on the front ones to come


and the diff bearing kits have showed up finally so i got cracking on putting the diffs together

[vinceparts]

awsum build mate, just put a set of rs500's from 4wdbits in my double cab, alot better than the munroes that were in it previously, and awesome price too

[jakwoo39]

yeah cant wait to get it all together and see how it handles, ill get a fork lift under the tires (when they arrive) and where it lifts to the highest point thats where ill mount the shockies to allow maximum travel

[jakwoo39]

i have now set myself a deadline, i booked the certification in for the 5th of december to get myself motovated to do get this truck finished

but ever since everything has turned to shit

went to put the front diff together and i both of my pinion nuts (inc the one for the rear)
so had to wast an hour or so to whip up some new ones but learnt my lesson and made them from high tensile


then i started work on the shackel reversal
sorry for the low rate pics but it actually does look quite good in person




then when i put the weight on this happened


you can also see there would have been little upward travel aswell so i had to put the extra leaf back in bye bye ride comfort

then it was time to put the diff head in


and now i have noticed the castor angle is wrong and the front driveshaft is too short so the front housing will be coming back out and ill be making a new drive shaft

[crazyclark31]

have heard that the hanger should sit on more of an angle when weight is on. Think its round the 30-35deg from vertical. would help stop them from inverting like that.

[jakwoo39]

i have put the extra leaf back in now and it is sitting at a good angle

[mbw]

since im well over half way now i thought i would do a cost report up to this point

hi steer kit - $600
4 wheel bearing kits and 4 kingpin bearings - $290
8 cans of paint - $85
air locking diffs inc post - $1400
4.56 ring and pinion gears inc tax $1150
getting springs reset - $400
Speedo Cable - $60
Speedo drive gear - $100
Spring bushes, brakes, brake rotors ect - $600
tires and rims - $2500
axels - $200

this is a rough estimate of what has been done since i started SOA conversion up till this point

and whats to come...
diff bearings
diff gaskets
shock absorbers
cert and WOF and reg costs
new front diff housing
spot lights

so as you can see i have made most of the major purchases already but i have already crossed over 10 grand owing counting buying it, but just doing the soa would not have been so expencive

Hi, Do mind me asking where you got your air lockers from? $1400 for both delivered seems a good deal.

[jakwoo39]

got them on alibaba.com from nanjing ido import export co

[mbw]

Cool, thanks.

Whats the quality of the locker and compressor like?

Which one did you get? As far as I can find on the net, I'll need a RD142 for my 86 bj74, but not 100% sure.

Did you have to buy 2 full sets?

[jakwoo39]

ahh i initially bought rd33 but they upgraded to rd142 just after i bought mine so i got sent rd142.
lockers look in really good nick cant tell the diff between an arb one and chinese when side by side.

only problem was i had to polish 0.03mm off the carrier bearing surfaces as they were a bit too tight for my liking

and the compressors are shit but they come free with a locker so cant whine too much

[jakwoo39]

bit of an update been really busy on this truck and havnt had much time at home to post so heres how its getting on

all the diff works




back lash



and a few more of the truck together

[jakwoo39]

the truck is all finished now,
been to busy to post so here are the pics of it all finished



and the new cert tag which only took a week to turn up!


and my air locker switches which get played with alot


and my steering which took up many many hours



extended bump stops


suspension



and shockie mounts



some of the toys


looks a bit better than the temp and rollover gauge






and something to actually run all the 12volt accessories because the compressor cooked my old one

[jakwoo39]

if you are looking at doing one of these conversions, im happy to post more pics of parts close up and give more details

might even be able to make some more of the parts in exchange for some beers

Throw a small intercooler on it.. I reckon mine ran heaps better with one. basically put a 90 degree bend at both sides of the pipe that goes across top of motor, piped to front. cant remember where the cooler was mounted and cant find an old photo.

not really interested.in a front mount but might ho for a top mount if somebody can suggest a good intercooler to start with

[109]

Nice work mate , great result

[crazyclark31]

a subaru one would be a good size. with the y pipe would be a simple fit up

Whereabouts in Dunedin are you? Toying with doing something simular with the rear axle on my truck - if you don't mind me having a look PM me with some contact details.
