Phizinza Posted March 18, 2014 Share Posted March 18, 2014 So I repositioned the control arm mounts to get better camber, and by moving them just 14mm or so outwards I've encounted a problem with the DOJs. They are almost at full extension and one side wants to click now every so often. Ages ago I remember reading about using ea82 rear DOJs on the rear of ea81s to get more extension, is there anything like this for the front? What DOJ cup will fit my shafts?

bratman18 Posted March 18, 2014 Share Posted March 18, 2014 Pretty sure you can use ea82 stuff for the front too. You'd have to use ea82 knuckles and I think tie rod ends too. Quote Link to comment Share on other sites More sharing options...
Skylar Posted March 18, 2014 Share Posted March 18, 2014 I believe Uberoo had legacy Dojs on his ea81 rear axles ... Quote Link to comment Share on other sites More sharing options...
Uberoo Posted March 18, 2014 Share Posted March 18, 2014 I believe Uberoo had legacy Dojs on his ea81 rear axles ... Yep!I believe you can change the doj end of front axles but not the cv end. Quote Link to comment Share on other sites More sharing options...
Phizinza Posted March 18, 2014 Author Share Posted March 18, 2014 They would be 25 spline? I haven't extended the control arms enough to fit the whole length of the ea82 shafts I don't believe. I haven't measured it but I did that mod on another Brumby. Quote Link to comment Share on other sites More sharing options...
Uberoo Posted March 19, 2014 Share Posted March 19, 2014 no all rear doj are 23 spline.the front DOJ's from a turbo ea82 might be longer and would be 25 spline or there is 25 spline EJ DOJ. Quote Link to comment Share on other sites More sharing options...
jono Posted March 19, 2014 Share Posted March 19, 2014 the L Series EA82 front shafts themselves are about 40mm longer than MY/Brumby front shaft Quote Link to comment Share on other sites More sharing options...
Uberoo Posted March 19, 2014 Share Posted March 19, 2014 (edited) IIRC EA82 doj are about 1/4" longer than EA81 stuff,EJ stuff is about 1/2" longer.So EA82 DOJ's on EA81 shaft would be 6.75 mm longer and EJ stuff would be 12.7 mm longer.If you are pulling out the DOJ with 14 mm extension then the EJ stuff might be your best bet.I think you have to use front axle DOJ on the front axle because rear DOJs are smaller in diameter than the front stuff.I think I had a front axle DOJ go bad on me so I tried to use a rear doj to fix it and it wouldn't work. EDIT: according to my digital caliper a EA81 front DOJ cup is 76 mm while a legacy rear doj cup is 74.55 mm.So the front is just slightly bigger.I believe the shaft splines are different too between front and rear.

Phizinza Posted March 19, 2014 Author Share Posted March 19, 2014 Ok. I'll be building up a gearbox for this car so it would make sense to use 25 spline stubs and ej dojs... Now I just have to make sure the joints on my Brumby are compatible with the EJ shafts DOJs I have. So many times I've pulled apart shafts from EA81s finding 3 bearing joints, small 6 ball, large 6 ball, different spline count on shaft itself etc... I would of have liked to keep the front shafts 23 spline for when an emergency happens and i need a quick fix, but if the EJs are 12mm longer then that's what i need.
