nicksubaru Posted September 1, 2017 Share Posted September 1, 2017 So i have be looking and looking can someone if they know it, link a thread with brat cv axle upgrades. Mostly for offroading. Another side question, would the ej 5 speed single range or the ea 5 speed duel range be a better choice. I have an ej22 thats been rebuilt that im planning on using. Im hesitant of pulling the ea 5 speed d/r because its in a fully running ready to go ea82. What's wrong with using the 4 speed brat tranny? Ive read that some people say the ej22 will destroy the ea 4 speed. Thanks Quote Link to comment Share on other sites More sharing options...
skishop69 Posted September 1, 2017 Share Posted September 1, 2017 To my recollection, both the 4spd and 5spd DR trannys will take 200hp before failure is eminent. Someone here had some dyno proof, but I don't recall who. The weak point of the 4spd is the third gear blocking ring. It wears out causing the shift to third to grind. The 5spd doesn't do this. There's been tons of EJ swaps with the 5spd DR with no issues so those that did blow must've had a previously unknown tranny issue. If you're off roading, you want the DR, not the EJ trans. You want the low range. As for the EA 82 axles, you're stuck. The weak point is really the stub shaft in the tranny and diff. It will snap well before a CV when put under a hard load. 1 Quote Link to comment Share on other sites More sharing options...
nicksubaru Posted September 1, 2017 Author Share Posted September 1, 2017 That you know of, is here anyone who's fab a custom cv axle? Quote Link to comment Share on other sites More sharing options...
skishop69 Posted September 1, 2017 Share Posted September 1, 2017 I know there are places that will make custom assemblies, but they charge a pretty penny to do so. There are hybrid combos mixing different Subie shafts and CVs, but I believe those were made for swapping in EJ running gear. I never paid a lot of attention to it since I've never had any issues with my NAPA axles. Someone who knows more will chime in. Quote Link to comment Share on other sites More sharing options...
nicksubaru Posted September 1, 2017 Author Share Posted September 1, 2017 What's the difference between ea81 and ea82 cv axles? Why do some people say you have to lift evenly the ea81 and the ea82 can take a little bit more on the strut towers? The weak point is the cv axles. Im just trying to figure out what i can do to upgrade the cvs for this reason. Im thinking of possibly remaking the control arms Quote Link to comment Share on other sites More sharing options...
86BRATMAN Posted September 2, 2017 Share Posted September 2, 2017 The issue with lifting the ea81 is that they have bad cv angles from the factory. Lifting them unevenly just exaggerates the problem. Quote Link to comment Share on other sites More sharing options...
Gloyale Posted September 2, 2017 Share Posted September 2, 2017 The issue with lifting the ea81 is that they have bad cv angles from the factory. Lifting them unevenly just exaggerates the problem. it's a function of the length. You get more travel at the wheel out of the longer axles, using essentially the same joints.

Larschung Posted September 9, 2017 Share Posted September 9, 2017 Ive had to replace my front axles almost every year (praise be the lifetime warranty) id love a good alternative Quote Link to comment Share on other sites More sharing options...
GeneralDisorder Posted September 10, 2017 Share Posted September 10, 2017 Yeah we have fabbed axles. It's not that hard if you can fab press tools to take them apart without damage and have a master (and I mean this in the strongest sense possible) welder that can shorten the shaft, weld them together, true them on a lathe, and the sleeve them.... etc. We shortened a set of EJ axles for doing a 5 lug swap on an EJ swapped Brat for rally-x. I would say it's probably beyond the capability or price of 99% of the EA community. It's easily $500 per shaft. GD 1 Quote Link to comment Share on other sites More sharing options...
nicksubaru Posted September 16, 2017 Author Share Posted September 16, 2017 $500 per shaft... Yea i think just braking them and replacing them would be cheaper... Lol Quote Link to comment Share on other sites More sharing options...
GeneralDisorder Posted September 17, 2017 Share Posted September 17, 2017 $500 per shaft... Yea i think just braking them and replacing them would be cheaper... Lol You think that's high - the chromoly WRC axle shafts (just the bar, no joints, boots, grease, etc) for STI's are about $1200 per each.

nicksubaru Posted September 18, 2017 Author Share Posted September 18, 2017 Thats a little ridiculous for cv axles unless then are so solid that its rare for them to brake Quote Link to comment Share on other sites More sharing options...
GeneralDisorder Posted September 19, 2017 Share Posted September 19, 2017 Thats a little ridiculous for cv axles unless then are so solid that its rare for them to brake It's not ridiculous for the guys shearing axle bars in stage rally. The six speed is strong enough to do this. Stock STI axles have been tested at the track and will do approximately 30 hard, sticky launches at stock power before the axle shaft shears off.
