myshoeisonfire Posted January 23, 2006 Share Posted January 23, 2006 Ive got an 83 ea81 wagon with 4x4 hi/low range - I was wondering if there is a way to weld the gears in the back, or otherwise lock the diff in the rear of the car? I have never opened up a subaru rear end - I dont know if welding is even possible, or if its something i want to do. I just want something as close to a locker, or posi as possible, as i only use this car off road thanks! -Dan Link to comment Share on other sites More sharing options...
subarunuts Posted January 23, 2006 Share Posted January 23, 2006 Welding is pretty easy actually. Weld the spider gears to each other at each corner (4 welds).... I like to use a nice grade 8 bolt and jam it in the gears at the point where I make the weld. Never had one break yet. Don't weld the gears to the carrier as that is cast, and brittle. The gears are hardened, and will make a much tougher weld. Link to comment Share on other sites More sharing options...

subarunuts Posted January 23, 2006 Share Posted January 23, 2006 It can be done on the car, yes. It's best to remove it so you can be sure there are is no spatter left inside the diff before reinstalling. I used brake cleaner as it leaves no residue to clean the gears. Since I used a Lincoln 220v MIG to do the welding I could not comment on the rod type. Link to comment Share on other sites More sharing options...
