Still a fair bit of weight on that front tyre unless you have very low pressures. Very impressive

Hi Steve,
Where did you get that tail shaft adapter from?
I am wanting something similiar for my 93 MU to act as a spacer and stop the tailshaft vibration from a lift.
Thanks
Jimmy.

Nope - those tyres are running street pressures... I'll put the Simexes on for the next instalment... which hopefully won't be too far away... really want to get rid of that crossmember first. The tailshaft adaptor I had machined up specifically for the task. I gave the driveshaft from the MU (for bolt-pattern measuring) and the Hilux driveshafts to my engineer and told him what I needed. He used the old rear driveshaft as the main portion, and welded the double cardan section to it with a machined adaptor. I would have prefered the slip joint at the other end, but this was the easiest combo. Not sure how the cardan will survive constant power in the rear, only time will tell. The adaptor uses countersunk cap-screws to bolt it onto the output flange, and then has 4 tapped holes to bolt the driveshaft onto. Its really not going to work perfectly until I rotate the axle to point the pinion on the diff straight up the shaft, but thats waaaay down on the priority list at the moment Steve

Well, got a few bits back from the engineers just before I went away to Welly for a week so managed to sneak a couple of hours to muck about when I should have been packing... Heres the new arm to go on the passengers side knuckle. Its the flipped arm to replace the Hilux one I was using. The main thing is that its shorter and should give me better steering lock. I also had new studs machined since I fitted the first set to another truck I was working on (a Surf SAS) Here is the crossmember with the gearbox mount sitting beside it. I've had to trim some cooling fins from the gearbox beside the front output flange to get it to fit, and modify the two holes that the mount studs go through too... measure twice, drill once I'll also need to get the holes milled down since the studs are designed to go through about 6mm of steel and I have a 16mm thick crossmember... Wooo! My new headache solver arrived One 4.8 ratio high-pinion prado diff for the front of the truck. Bolted into the new front axle I am building up for it (The one in the truck at the moment belongs to my old Hilux and needs to go back into it at some point) So - I didn't get too far, but I sorted some things that had been waiting for a while to get sorted and I made some progress on the Surf I'm doing as well so all in all not a bad morning - and it got me out of packing Steve

Well, gave the crossmember back to my engineer while I was away and he did a little milling to tidy up my miscalculation. I managed to get the two pieces of angle fitted and welded to the chassis and fitted the crossmember to the mount ready for drilling. It will be attached with 2 3/4" HT bolts on either side Once its all fitted up I'll pull it all apart, clean it up and paint it then re-assemble it. Oh, and Mulover - I'll measure it up when I can get back down there through the huge snow drifts The crossmember in place One side, ready to drill for the bolts The milled stud-holes Steve

Today I got the new shocks mounted up to the front axle... due to me not thinking while working I made the shock mounts for the new shocks from 3mm, not 4mm plate as I had intended... didn't even notice until I went to weld them on and thought, "Crap, they look puny and weak..." So, I did the only thing I could... threw them in the scrap bin and made some new ones from 5mm plate They still need trimming on the corners, but they are on there pretty solidly. I will add a brace across the inside end to support everything and provide a bit more strength to them. But I'm not providing any close-ups of my welding to prove any of this The shocks I am using are not my 9012's I've had sitting here waiting as they are just too long for this truck - I can't fit them in without a 3" body lift - and quite frankly the thing is too bloody high as it is :shock: . Since I sell MaxiTrac gear I figured its only right to put MaxiTrac shocks in with the MaxiTrac springs I'm already using... so these are off a Mazda Bounty - believe it or not they are the longest travelling shock I can find in the range... off a Mazda Bounty! bloody hell... oh well, now they're off a MU The rears will be off a GQ Poo-troll as they are the same fitment as a Hilux and a MU so I can mix'n'match existing mounts and get that end done quickly Besides, they are the second longest shocks available in the range, and were on the shelf in the warehouse when I went looking:) Here is one fully extended beside a standard Hilux front shock: And heres the axle with the two shocks mounted - the compressed one still has quite a bit of compression left - I should be able to get nearly 40-odd degrees out of the front axle before running out of shock travel - probably more than the springs will allow...

Well, the rumours are true... I drove the MU home the other night. There has been a huge amount of finishing off work done in the last few weeks, and not much of it documented... sorry, I know a lot of you live for stories of welding and grinding The last few things have been finished... the crossmember is finally in... no more G-clamps holding the truck together... 16mm holes through 26mm of steel plate upside down with a stuffed drill that either stalls or runs at 12,000RPM... now THERES a story in itself... The shocks are fitted in the front with some basic towers that may or may not hold up to abuse... I have some hoops to go in if they don't: Steering modified AGAIN... measure twice cut three times is my new motto... The arm now looks like a limp thingy... but its nearly right... could have got away with a flat arm in retrospect... The front driveshaft is in... had to shorten it by about 25mm (15mm for the adaptor... it was within 10mm of perfect overall, straight from a Hilux) And the finished product... not quite ready for cert, but close enough for me to want to go play in it :

Looking good Steve. Did you have to cut your bumper mounts off for clearence? I'm going to have to as well. I like that HP diff, do they come in 4.56 ratio, I know they are bundera's or landcruisers over here but don't know if the bundy/prardo came in that ratio?? The only thing I don't like is your steering arm, you are putting a lot of stress on those bolts, and you are relying on them for steering which I would say is very important, espeically when traveling over 80km/h..... I would at least weld/laminate them together and brace when you have the correct angle for them. Here is a pic of my old one. Oh and my new ones as well. welded arm, I got a guy at work to weld these, we heated them first then welded to make sure it was strong. New ones, these are high steer arms from sky manyfaturing.

Hi Jan... yeah, I'll take a photo of where I cut... because I did most of the build with it rolling on 31's I never noticed the front bumper mounts/body mount wings would be in the way... until I bolted the new tyres on and drove it out of the shed... went to turn as I went out and drove straight into the fence! I will fit a high-steer kit to it - having one custom made as we speak... I realise the forces I'm exerting although they are custom machined high-tensile studs, double-locked with cone washers into the top and bottom arms. (its got the bottom arm, then cone washers, then spring washers then a torqued nut then another cone washer then the top arm, then another spring washer then another torqued nut) Its not ideal, but I believe its strong. And I'm not sure that welding them together is that much stronger... I'm not keen on welding forged steel... not even when its pre-heated. The high steers I'm getting will be about $450NZ per pair... what did you pay for the Sky ones out of interest? The problem with your original arm and my design as well is that once its all fitted the drag link hits the chassis under flex... those high steers should just about have the problem solved. I'll be keen to see ramped photos one they are in... I'm going to ramp mine in the next couple of days so I'll take a few snaps and post them. Oh, the HP diffs are either 4.3 (as found in 3 litre turbo trucks) or 4.8 (2.4 TD prados and probably bunderas as well). You just might get away with going 4.3s in yours with the 1UZ... I believe Isuzu make a 4.3 diff in some of their trucks, no ideas which ones tho. Failing that, the Surf rear axle will virtually bolt straight in... handbrake and disc-brake-mod to the rear is what you'd need... I'm doing that in the next week sometime - before cert. Steve

Do what I did... just get it going and hold off on all the project-based things you want to do with it... its a toy, go play Having said that, mine went off the road in March, and was driveable again in January, so I was without for a very long time... How did you get on with the front driveshaft by the way? ever get one going? You must have been 4WDless for ages... but then locked up with that flex it doesn't matter too much I suppose Anyway, hurry up and get it going - I'll be in Oz sometime this year, I'd like to come see it (going! ). Steve

Well, I broke my front driveshaft... Hilux d-cardan front shafts (Therefor any Hilux slip joint, they're all teh same size) do NOT have enough slip for this setup I got the truck a little airborne along the beach and when it came back down the shaft had parted ways in the middle Whats worse is that was the second time I had! The first time it just slipped back in but this time I was travelling at speed and so by the time I had stopped... well, it was no longer the right shape Never mind, all part of the fun... until I decide what way I will go with the dual transfers I won't be spending too much rectifying the problem... I'll just make something that will do and limit the front travel a little to stop beating the snot out of the underside of the truck again Anyone notice how easy it is to change the oil filter on a SAS'd MU? I'd raet that as the #1 bonus of having done the swap... I just walk under the truck, reach up, unscrew it and screw the new one on Who needs a hoist... Steve

LEGAL! ;D Tuesday, amid being ill managed to make it down the the certifier and after much scruitinisation (is that even a word? ) it was ticked off as needing a warrant of fitness, rubber flares and a balance report on the custom rear shaft. WOF sorted as of that evening, and flares will be picked up tonight after work... the shaft I need to drop in for balance-testing and its all done Whew!
