Broken rear diff question
I just bought a 90 Legacy Wagon AWD with a "broken rear diff". I'm going to be bringing it home tommorrow. Assuming that it is actually a broken rear diff(I bought this car for the motor only), what could I possibly expect to get if I force FWD with the fuse? Or if I pull the driveshaft? I just need to drive it about 15 miles home. Thanks.

Got four jackstands? To take the guesswork out of what's wrong with the car, why not jack it up at all four corners, start it up and put it in gear? Then you'll be able to see what's going on with the car. ;)
I wouldn't crawl under the car to listen to any noises up close, but if you have a long hollow tube (like a broom stick), you can put it next to any areas where you hear sounds coming from and stay a safe distance away! :) 15 miles isn't very far, but it depends on how rough those 15 miles might be... Will you be on the interstate going 70+mph? Or on gravel backroads going up and down steep inclines? These will be harsher on a car with a failing rear diff, compared to driving on secondary roads at 35-45mph. -Chike P.S. You said you bought a '90 Legacy? I'm not sure if they came with an R160 or R140 rear diff, but if it is the later, they have the tendency to break easily with very little abuse. The difference in size between these two diffs is shocking to look at! :eek: These are two pics that Green_eyed_lady snapped when Svxfiles and I did my first trans swap to 4.11 gears (did a second swap to 4.44's about a year later!). The 4.11 4EAT trans I bought came with a R140 rear diff, but I went with an R160 for obvious reasons...

If you don't stick the FWD fuse in (and the rear diff is really broked), duty solenoid C will go crazy and make the split 50-50 and you'll burn out the clutch packs doing that. If you stick in the FWD fuse, you should be okay. This makes the Duty Solenoid C ignore the speed of the rear differential and completely disengages the clutch packs. However, running FWD for long periods of time is a no-no because the clutch packs aren't meant to be kept like that. I think 15 miles is okay, as long as you don't race it. It's a 90 Wagon, so it's not going to be a racer...unless it's a Touring Wagon :D.

Thanks for the input you guys! What size fuse does it take, or does it matter?

It's located in the engine bay fuse box. The fuse box lid will tell you what type of fuse to use in the Legacy wagon though... -Chike |
Pictures Please!!!

As I recall, it's a 15 Amp Fuse into the FWD slot near the right strut tower.

That was probably on a lift ben. I'd feel much safer if it were on a lift, but I fear what would happen if I did it with the stands I have now :(
