sounds good, removing swaybar does help mine certed without one which is good, you can also weld the front diff alot cheaper but makes the steering VERY heavy have done it on 2 isuzus 4 nissans and 1 hilux, all ok but the nissans, they blow cvs and snap axles clean in half

Might stay away from welding the front diff as sounds a bit like I'll have the handling of a tractor haha..
I was just looking at swaybar at the weekend as I finally got round to balljoint flip and torsion bars crank.. I didn't remove the bush completely, just undid the nuts either side, to remove completely do you have to jack up one side and let the other side drop?
I was wondering if I could swap the nuts for wing-nuts for a quick release option or do you think wof man wouldn't like it..
defo going to remove for the next trip cant wait to see difference haven't had a good look yet but I presume I'll have to shorten the bumpstops at the front aswell to get more flex?. can you buy low profile bumpstops ready to fit?

cheers

Not a fan of combining low bump stops and ball joint flip. That really pushes the cv angles to the limit. I wondered the same thing but at the time the wof person I was using was going to want to send it to the certifer so it didnt happen. Current wof man might pass it. He knows the bar comes off as soon as it gets home with sticker He also has noticed that the tyres have no wear in 5 years. He did let missing rear bump stops pass.
I should of removed the swaybar completely before I had certification done but no matter.

haha he must get trucks in like that all the time... did you tell him that you only drive it twice a year, to the wof station and back.. :)

Do you tie your swaybar up out of the way somehow when its not connected or just let it bounce around?..
So do you recommend leaving rear bumpstops standard aswell?

wrote a big story and it didnt load so in short, bumpstops cannot be modified in anyway, can fit slow slim bumpstops but have to mount to factory positions or needs a cert, my truck runs 33 with 2" sus and 2" body lift has 5mm gaurd gap in rear full flex, no bumpstops tyres rub ALOT, vechiles come standard with no swaybar, thats why i removed mine, remember every mod you do makes it that much easier for insurance to get out it not the wof you have to worry about

Leave it loose but my center bushes are still good enough to hold it out of the way. If it falls back onto the watts linkages it will probably make a huge rattle.
Rear bump stops are missing at present but not by design. Noticed this while having third go at handbrake for wof. Asked wof man about this after the sticker was on the window. He said "I noticed that thought it was meant to be that way" Now the tyres rub the guards on articulation so I will have to fix Who knows how much travel this leaves in the shocks.
Could you please measure the rubber part of your bump stop for me so I can get the right ones.

I looked at the wizard ones which look much the same. I can get 3.1 bighorn ones easily next weekend but away 4wding for the weekend this weekend so it will have to wait. 50mm lift with hd springs and still it hits

wizard is coil and the bump stop mount is sufficiently close that a few minutes with a file is the most it should take to make it fit.

So I ended up making some easily removable bushings for my sway bar by trimming the thread down nd replacing the nuts with wing nuts so I could remove them easily on the go.. problem is I then failed to ever check them so the top bolts on both of them have worked loose and disappeared along with the top rubber bushs and washers.. do you know if its possible to buy these bushes separately or do I have to buy the set up? cheers..

I thought about setting up my swaybar that way but would of used long threaded high tensile rod for the linkage. My idea was hard mounting at the bottom like factory (including bushings) then the wing nut facing upwards then the lower bush for the top the sway bar the upper bush then a nut with a nylock on top for a locknut. The threaded rod would of been about 50 to 100mm longer than the standard bar and the wingnut tightens upwards towards the sway bar.
Then I realised how much of a pain it is climbing under a car dripping mud in your face just to set the swaybar at the end of a fun day. Hence my current lazy set-up. Handling is affected by removing the sway bar but not by much

its only 20 bucks or so for a set of bushes if you use urethane ones. What places to buy them do you have down there?

I must say I have to go out of my way to notice any difference in the handling on road.. I notice a bit more wobble when swinging left to right to left but dont have to do that to often on the road :) maybe negotiating roadworks at speed :)
If there only $20 I might aswell pick up some mew ones.. I've got a BNT and a Repco..
