scoobyclimbs Posted August 8, 2010 Share Posted August 8, 2010 Since, ea81 axles are getting uber rare now . I was thinkin' of swapping Ea82 trailing arms . This way I could just use EA82 axles and not having to make hybrids(ea81 shafts/ea82 doj's). Given it would be a few inches wider track , it also looks to be a straight foward bolt on swap. Anyone done this ? any issues? Quote Link to comment Share on other sites More sharing options...
Gloyale Posted August 8, 2010 Share Posted August 8, 2010 I'm planning on doing it this week before the WCSS. In my case, I already have an EA82 front subrame and arms, so my front is wider than the back. I currently have different offset rims front and back to match the track widths. I am hoping the swap of the EA82 arms onto the back works easily, and will widen up my rear track. The biggest things I've noticed in preparation so far is that the bolt holes on the EA81 subframe will need to be enlarged for the larger EA82 pivot. Also I am not sure how the bump stop action will work out. Because there is no coilover on the EA81 to limit uptravel, bump stops are essential to keep the inner joint from overextending when the wheel is compressed (hill climbs) Do you have trailing arms for your project? I've got a set if you want em. I'm sure you've got something subaru to trade. (I'll take the H6....lol) PM me Quote Link to comment Share on other sites More sharing options...
scoobyclimbs Posted August 8, 2010 Author Share Posted August 8, 2010 Hey, the H6 is yours...for the set of trailing arms....sounds like a good swap to me...lets do it... call me 503-314-7535 Quote Link to comment Share on other sites More sharing options...
jbbvw Posted August 10, 2010 Share Posted August 10, 2010 Have you done a side x side comparison of the EA81/EA82 trailing arms? I was also looking at doing this after I did my front control arm/axle swap. When I compared the two, there seemed to be very little if any difference in length/width, it's the trailing arm mounts on the body that are farther apart from what I saw. Just something to think about before you get to excited like I did. But if you know something I didn't notice, please tell. Jesse Quote Link to comment Share on other sites More sharing options...

I haven't compared to installed width to determine if EA82 rear axles will work lengthwise after swapping arms. gonna be working on this today.

Gloyale Posted August 13, 2010 Share Posted August 13, 2010 Well......I'm not sure if it will work with EA82 axles. The arms are longer by about 3/4 inch. But the EA82 axles are longer by about 1-1/2 inches. However it seems that at least early EA82 alxes will "compress" down to a length that seems like it would short enoguh to fit. Not sure. Gonna try and mount a set up and see what happens. The later EA82 axles with a slidng DOJ on;y on the inner end, don't comress as far.....so those definately won't work.

jbbvw Posted August 17, 2010 Share Posted August 17, 2010 Any luck with this yet? I'm kind of anxious to see if this works. I've been thinking about it alot lately, just havn't had time or parts to play with it. Jesse Quote Link to comment Share on other sites More sharing options...
Gloyale Posted August 17, 2010 Share Posted August 17, 2010 Don't think it will work. The EA82 axles are too long, even with the EA82 arms on there. Jbbvw was right, it has more to do with the mounting points of the arms than the length of the arm itself. Guess I'll just have to keep mounting up Legacy and EA82 inner rear cups onto my old axles. As long as the shafts hold up, I can replace joints all day. Quote Link to comment Share on other sites More sharing options...
Speedwagon Posted February 11, 2011 Share Posted February 11, 2011 If you do a lift at the same time as mounting up EA82 trailing arms, can you widen the mounting points and fit the EA82 axles? Quote Link to comment Share on other sites More sharing options...
MilesFox Posted February 12, 2011 Share Posted February 12, 2011 You will need to chop in the whole ea82 subframe. The ea82 trailing arms will bolt in, but you will not gain a wider track from that alone. Quote Link to comment Share on other sites More sharing options...

MilesFox Posted February 12, 2011 Share Posted February 12, 2011 If you have the complete ea82 tubeframe, then yes, make a lift block that adapts it. What i am saying if you just bolt in ea82 trailing arms to the ea81 subframe, they are in the same place. You will have to adapt the ea82 coilovers by modifying the mount in the wheel well (see McBrat's red brat for an example of the coilover mount mod.) ea81 and ea82 trailing ars are dimentionally similar, from the pivot bolt to the backing plate, width wise. ea82's are no wider than ea81's Quote Link to comment Share on other sites More sharing options...

Lifting the subaru there is no change in teh trailing arm mountings. The Whole subframe drops. The trainling arms are a fixed distance from eachother unless you start cutting and welding sections of the subframe. Quote Link to comment Share on other sites More sharing options...
Speedwagon Posted February 14, 2011 Share Posted February 14, 2011 (edited) Lifting the subaru there is no change in teh trailing arm mountings. The Whole subframe drops. The trainling arms are a fixed distance from eachother unless you start cutting and welding sections of the subframe. I guess I'm not saying it correctly then. What I'm talking about, is apparently swapping the whole subframe from the EA82 car to the EA81 car, while doing a lift. As I understand it, that should fix the width issue, and the lift should allow the moving of the mounting points to allow it to bolt up. I have a complete EA82 parts car: I can take any part of it off to put on an EA81, I just want to make sure I'm thinking of it correctly.

bratclay Posted February 17, 2011 Share Posted February 17, 2011 Let me know what you find out speedwagon. Cuz if I keep my brat. Im goin to want to do the same thing. When I lift it, I want to use the front and rear subframes from the loyale parts car I parted out. Thanks Clay Quote Link to comment Share on other sites More sharing options...
