front axles/suspension, EA82 v EA81

Featured Replies

As I continue to consider using a front LSD in my brat. The issue of front axles keeps coming up.

 

I can't find an axle stub that will work with the LSD that I want with 23 splines.

 

So I have to try to make some hybrid axles.

 

Would it be possible to use EA82 front axles? Obviously they're longer, but it seems to me, lengthen the control arms, and some EJ TREs, and done. On paper, EA81 and EA82 axle outers look the same. RockAuto says they're both 30 spline outers. Would an EA82 axle work with an EA81 knuckle and hub?

 

 

Actually, while I'm on the subject. I have the front suspension from an '87 EA82 (leftovers from a 5-lug swap). What would it take to use the EA82 control arms?

I can't answer your cv question, but I have fitted XT-6 control arms to my brat, which are basically the same as ea82 from my understanding?

 

anyway here's a link, it's not all that bad if you have access to a welder and don't mind some fab work.

With the XT6 control arms the front was much wider than the rear. I have 1 1/4th wheel adaptors in the rear (which are a bit wide) to make up for it.

I know of a guy who uses ea 82 stuff on his ea 81 hatch wheeler. I can't be 100% sure of the specifics, he does have a wider than stock track due to using the longer stuff. I do know the ea 81 strut is smaller diameter where it enter the knuckle, so i believe you'd want to switch to ALL ea82 stuff and use the ea81 tophats. The part I can't recall on tat guys hatch is which crossmember he's using. I don't know if the width comes from longer control arms, or wider distance between the control arm mounts on the crossmember.
