80brat Posted July 11, 2017 Share Posted July 11, 2017 I just had the shaft seal replaced due to leaking and had bushings replaced on 4wd shifter. Drives and shifts good, but will no stay in 4wd, shifter will pop back up on hard surface, so tried going off road and when on hard dirt the same thing unless I am in soft soil after which when it hits hard ground it pops back up. Any advice? all tires the same size 13". Jason 910-783-8092 Link to comment Share on other sites More sharing options...
idosubaru Posted July 11, 2017 Share Posted July 11, 2017 (edited) someone else will probably know better, but here's a way to diagnose: push it into 4WD and disconnect the linkage at the trans. if it then pops out - that means you have an internal issue. if it no longer pops out then your linkage is compromised somewhere. if the linkage is disconnected and 4WD is working properly - then at least with it disconnected you can actually lock and unlock it manually by hand as needed as well. so then you're not left without 4WD in the snow, mud, sand..

ironworkerboomer Posted July 17, 2017 Share Posted July 17, 2017 My old 78 brat started that and it cost me a transmission rebuild. The gears were just wore out. This was years (decades) ago when you could still get them rebuilt. Link to comment Share on other sites More sharing options...
80brat Posted July 20, 2017 Author Share Posted July 20, 2017 Thanks, i think i may have access to a junk brat and trade out the transfer case. Link to comment Share on other sites More sharing options...

My guess is the trnas mounts are shot, and the movement of the trans relative to the body is causing the 4wd to disengage. Problem for EA71 and EA81 4wd cars. That is why in the EA82 they moved the 4wd shifter to the 5spd stay. So it is not connected/mounted to teh car body. So as trans jumps around, the lever moves with it instead of changin the engagement. Link to comment Share on other sites More sharing options...
80brat Posted August 9, 2017 Author Share Posted August 9, 2017 Got rid of the dually setup and now has normal studs with wagon wheels. Took off the mods, but don't know how to put the pics of them up. Still issues with 4wd and thin it was dually setup that did it. Link to comment Share on other sites More sharing options...
