Leading arm adjustment ?
Leading arm adjustment ?
Hello fellow 4wdr's.. Im after some advice..? I need a little more room up front for 35's and im in the process of cutting away the bottom gaurd section but I feel that it's not going to be quite enough.. Whats the rules for either re drilling the leading arm mount or making it oval and welding a washer where needed..? Anyone got advice..? not a Vice..lol 
Re: Leading arm adjustment ?
Just put a spacer at the rubber mount at the of the arm furtherest from the diff and push the whole diff forward.Hope that makes sense.Moved mine forward 14mm and helped with my issues.

Depends what vehicle?
As already said... One type you can pack out the attachment at the chassis...
You can use drop boxes...
Or elongate one of the holes etc etc...
If it looks factory and same thickness / strength why worry re rules etc etc....

Re: Leading arm adjustment ?
haha im hearing you
.. Just was wondering about geometry issues etc.. I plan to make it look as factory as possible just to ease the minds of the warrent guys as we all know they can get a bit flustered..
then you have to show them ya get outter jail plate..

Re: Leading arm adjustment ?
If I doi move the bolt holes forward.. Im no guru BUT will it change any geometry? as Ive looked at it
and thought about it
and argued about it
with mates and I cant see how it will...
as I got a hold of a maxxis creepy 35 x 12.5 and its big... and I dont have that much clearence.. and moving it forward will help greatly.. thoughts anyone
cheers
Re: Leading arm adjustment ?
Are you talking about the holes in the diff brackets? If so you wont get alot of movement, the arm is shaped to go around the diff, moving t more than a few mm will result in the arm hitting the diff housing under flex. You will be better off pushing the chassis end forward as mentioned above
Toy - Zuk chassis tub, hilux 4.88 axles and transfer, Nissan CA18DE motor and auto trans, sc12 supercharger, 32 10'5 simex, twin motor 8274 custom freespool. Well the parts are all there in various corners of the shed

Yip moving the chassis end.. or making a dropbox that will allow me to move the axle forward.. Currently working of a result.. when I get something on paper i'll post.
Re: Leading arm adjustment ?
only thing you need to pay attention to is that you don't go too far forward and cause a bind with the steering drag link or the panhard bar
If your after inspiration search safari and cruiser suspension lift kits.... they use a drop box to sort caster issues caused by the lift and the radius arm

Thanks Reece.. searching as much as i can.. I can by the sounds move it up to about 35mm 1 1/2 "without too much problems and if I make up some dropboxs I can do 2 things.. ditch my caster platesa and move axle forward.. but you know.. search.. research then ponder.. then search.. then plunge..
