ea81 front suspension on ea82?? MilesFox??
Posted 01 July 2004 - 02:56 PM
This is so that I can mount my front diff forward enough to keep the axles straight, without interfering with the ea82 suspension arms that go straight out sideways instead of angled back like ea81.
Another possibility is modifying the ea82 crossmember with new suspension points mounted in front of the old ones, with ea81 suspension arms.
Possibility 3: use the lift to move the ea82 crossmember forward, then mount ea81 arms in the crossmember to return wheelbase to stock while clearing the axles.
I've never been under an ea81 but I have seen many undercarriage pics of them and have heard of ea82 stuff on ea81s.
What are your thoughts guys?
Your help would be great!

i would vote for option 2, this would be the OPPOSITE of trashwagon, you would have to lengthen the radius rods. if yo are handy at frabrication enough to do so you could *possibly* adapt the ea82 swaybar mounts. that or make mounts for an ea81 swaybar.
this option would be ideal for an existing lift kit.
if you are handy at fabrication to build your own lift with offset, then i would vote option 3. less overall fabrication, and your discretion to how things line up!
if you offset an ea82 crossmember using the ea82 lower control arm, the ball joint hole will have to be enlarged. ea81 knuckles are too big for ea81 tierods, but you can swap inner/outer tierods with ea81/ea81 if they are BOTH power steering (mine was manual rack, lengthened ea81[was ea82 originally] tierod)

So I would have to modify the crossmember, modify the ea82 radius rods, and since I am using the ea82 rack with the ea82 hub, the steering would be no problem. Will the lower balljoint from the ea82 hub fit in the ea81 suspension arm? And will my track width be the same?
BTW, the swaybar left a long, long time ago

i think the hole on the ea81 will be bigger than the ea82 ball joint. it will still work, but may not draw tight, maybe some kind of sleeve will help that. or weld some in and drill out to reduce the hole and make it tight.

Or I could cut out the tapered sleeve from the ea82 suspension arm, and replace the one in the ea81 suspension arm Actually what I will do is move the whole crossmember forward 2" then bolt the ea81 arms in. I might even move the crossmember forward 4" to extend my wheelbase, reducing the overhang, giving me more firewall clearance against the 31s, better steering shaft angle, and allow me to pack the front diff up a little closer to the tranny Hmmm, back to the shop to figure out how that'll work
ok, if you are using the ea82 rack, here is your list
ea81 control arms
ea82 radius rods chopped and lengthened
i am assuming ea82 struts, that is what i recommend. but that may bring you to use the ea81 axle. maybe go with the ea82 lower control arm
ea82 inner outer tierods on ea81 power rack, but if ea82 rack swaps, youre good
the crossmember for the ea81 maybe narrower than the ea82 body, such as is so with gen 1 and gen 2 crossmembers
thinking of this, explore these possibilities:
putting ea82 crossmembers on the wrong side, to get clearance. chop and move swaybar mounts to front, or use ea82 swaybar(or both)
