88Subi4x4 Posted November 4, 2009 Share Posted November 4, 2009 i was thinking about welding my diff how.. because i want more traction on the road but how bad will it effect my daily driving...:-\ hard on drivetrain? Quote Link to comment Share on other sites More sharing options...
idosubaru Posted November 4, 2009 Share Posted November 4, 2009 (edited) that's a bad idea, it's going to cause binding and issues if you put any kind of miles on dry pavement like that. since others around here have welded diffs, maybe they'll be able to elaborate since i haven't done it. i would think the rear CV's are going to take the most pounding, so you could give it a shot and see how long a rear axle lasts. what kind of car/transmission? is this a PT4WD or FT4WD? if you want more traction on the road i would think your problem is not with an open rear diff. what car, engine, trans, and problems do you have with the current set up? you probably need better tires?

88Subi4x4 Posted November 4, 2009 Author Share Posted November 4, 2009 i dont think it is my tires i have some 29X8.5 swampers on it... i think i was just wondering if it was a bad idea i get pretty good traction haha but im always looking for new ideas:banana: Quote Link to comment Share on other sites More sharing options...
bheinen74 Posted November 4, 2009 Share Posted November 4, 2009 not a good move if you drive any on the road, as driving on the road you have to pull out 1 rear axle to drive on hard surface. reason-when making a turn, the inside wheel turns faster than the outside wheel, and a locked (welded) diff, with one axle turning faster than the other on turns, you will break your axle. it cannot take the twist difference Quote Link to comment Share on other sites More sharing options...
88Subi4x4 Posted November 4, 2009 Author Share Posted November 4, 2009 ok thats what i was thinking and since im in college dont really have the time or place to be putting axles in Quote Link to comment Share on other sites More sharing options...
The Beast I Drive Posted November 4, 2009 Share Posted November 4, 2009 Talk to One Eye, he will set you straight on welding your diff... Its not as bad as everyone has made it sound. -Bill Quote Link to comment Share on other sites More sharing options...
Markus56 Posted November 4, 2009 Share Posted November 4, 2009 honestly it not that bad. i installed a welded diff in my wagon 2 days ago and the only difference is you get looks when you make sharp turns. and taking out an axle isnt that bad Quote Link to comment Share on other sites More sharing options...
TeamCF Posted November 5, 2009 Share Posted November 5, 2009 I had a welded rear in my EA81 GL with about 26" tires. Never removed an axle. (in fact one is still seized in, never was able to get that one free) And I drove it like that for about a year before getting bored with the welded and going back to open. But it is also not my DD. The most pavement it sees is to get to the trails. Just watch the tight turns on pavement if you keep both axles in. There is a gas station in Sandy that lost all my business in the Soob while mine was welded just due to too much maneuvering there. And it takes a jack, a punch, a hammer, and about 5 min (or less) to pop an axle in and out. Quote Link to comment Share on other sites More sharing options...
Uberoo Posted November 5, 2009 Share Posted November 5, 2009 if your driving is mostly street then find a LSD and fit it into the 3.9 houseing. if your driving is a decent amont offroad- weld it and dont look back.. Quote Link to comment Share on other sites More sharing options...
chazmataz Posted November 5, 2009 Share Posted November 5, 2009 i had mine welded about 6 years ago and i would never go back to an open diff. , the increase you gain in traction out ways pulling an axle. plus there are cases where an open diff wont get you where you want to go but a welded will and it helps when your following jeeps and toyotas. installing/removing 1 axle isnt that bad, its like TeanCF said about 5 minutes and i would use a mat or something to lay on for when its muddy out.

chazmataz Posted November 5, 2009 Share Posted November 5, 2009 your lucky both of my axles are siezed solid to the splines...Ive even tried driving around with the rollpins out... man that sucks! i know of someone else that has that problem too. both of my cars the axles are free and all the other subarus i've worked on the axles all just slipped out with no problems.

monstaru Posted November 6, 2009 Share Posted November 6, 2009 do it. and when your axles get siezed ,beat,em break um , whatever you have to doto change them out so that you can have fresh cups with anti sieze on the splines....... i imagine a hot wrench has its attributes as well, but i have never used one.....so i dunno. then taking an axle out is not an issue.it literally takes 5 minutes after the first time... who knows,maybe you can make the record in replacing axles....... cheers, brian Quote Link to comment Share on other sites More sharing options...

torxxx Posted November 7, 2009 Share Posted November 7, 2009 I had a welded diff in my lifted 86 wagon. it wasnt that bad on pavement. I live downtown with lots of one way streets and tight turns so in the summer I pull it out and winter I put it back in. Never broke an axle from it but I have side swiped a few curbs and snowbanks with the rump roast end from having to MAKE it oversteer to turn.
