lower control arm mount position? (diff end)

[TOY-08V]

heres a question for all the gurus out there, while at tuff truck i noticed a lot of the trucks had their lower control arms mounted above the or on top of the centre height of the axle. ive been looking at changing my 3-link rear to a 5link and was thinking of using one of the original diff mount holes for my 5link, it sits slightly forward and above the centre line of the axle.

Just one question , What's wrong with the 3 link , Cheers Paul

lack of travel, its basically the same setup as a nissan front end.

Got any photos of your current setup , Can you fit a A frame , Or possibly a 4 link and loose the panhard rod , this is the main reason you might not have much travel , also your bushes on your lower arms restrict travel , and yes most of the guys mount there bush mount on the centre of the diff as the straighter they are the better they work. Don,t forget the vehicles at tuff truck are not usually daily drivers and they would not drive very well at speed , Cheers Paul.

Panhards don't lose travel. There are a hell of a lot of high articulation 4WD's out there running these, especially buggies.

I think you will find the lack of travel if he is running raduis arms is the binding of the bush's that is part of the setup. Same problem as the GQ/80 fronts. Panhards dont limit travel if done properly, and also help if you want to run linkage steering (and stay road legal) in the front end. A A-frame/ tri 4 link only moves in the verticle plane, meaning that bad bump steer will result when a linkage steering is used (unless you do what Glen Dobbin has done and run a push/pull linkage along his arms into a bell crank on the axle). If you run a panhard rod you can align it with your drag link and eliminate aticulation generated steering movement. There is nothing techincally wrong with lower links above the axle centreline, as long as the seperation etc of the linkages is still acceptable and the mounting points and links are strong enough for the job. I have seen a few street driven rigs with setups like these that have been fine.

Layto....

I give up , YOU WIN , I don't think the front of the vehicle was ever mentioned , Don't know where the steering comments came from or were needed , as for the buggy comments you are talking a totally different thread , as for the panhard they do restict travel whether using a radius arm or not. I think we need to establish what the vehicle will be used for before this thread goes out of control , No offence intended , Cheers Paul.

Here we go.

How does the panhard panhard restrict travel?

[TOY-08V]

ok, basically lay80n is on the rite track when he said its main lack of travel is due to the lack of diff twist due to the type of control arms im using (basically its a GQ front setup in the rear of my hilux) its a daily driver but im just chasing some more flex out of the rear some im thinking of changing it to something like an 80 or GQ rear setup considering that coils and panhard are all ready there.

in a rear end best bet for good flex and engineering would be to get the mounts off of a gq or an 80 and weld em in.
what rear diff are your running?

other option is guees would be an xlink. that is once i see one that flexs remotly like a 3,4 or 5 link

wat like this??


for reference they are 38's that its dropping below the door sills

[badger]

nice cranky isnt that a cranky link tho:P
they dont do that on gq fronts.......... not even chads puslux has that much travel

so i should clarify i havent seen a gq that can flex with a xlink
if anyone can prove me wrong id be a happy man .......... id xlink mine in no time:)

LOL.. ahh i get ya now

i'll get back in me box now
