spenceroo Posted January 26, 2016 Share Posted January 26, 2016 Hello to all! Okay....I have a 98 legacy manual trans awd sedan,,,the center ujoint on drive shaft is toast...I got the rockford ujoint to replace old one(have done staked in u=joints before)...but what I need to know is...if i unbolt just the back half of the drive shaft and leave the front intact,,,will i be able to drive car?and if so...can any damage occur.?I am hearing differing opinions and need the right one so I can arrange transportation to work if needed.....Y'all input would be just awesome....thanks Spencer Link to comment Share on other sites More sharing options...

Fairtax4me Posted January 26, 2016 Share Posted January 26, 2016 No. The way the MT works, it cannot be driven with the driveshaft removed. Link to comment Share on other sites More sharing options...
1 Lucky Texan Posted January 26, 2016 Share Posted January 26, 2016 (edited) really? didn't know that - I guess all the power just spins the output shaft ???? why wouldn't the center diff respond as if a rear wheel were slipping and lock power to the front?

1 Lucky Texan Posted January 26, 2016 Share Posted January 26, 2016 (edited) OK - long but good post found here;http://www.ultimatesubaru.org/forum/topic/73353-danger-in-driving-wno-driveshaft-on-awd-car/ It seems a working center diff 'may' be able to move the car with a DS removed, but it's very bad for the center diff. If you have a failed ctr diff that is locked-up, folks have removed rear drivetrain parts and 'converted' to FWD. If the center diff has failed by leaking internally, it is unlikely to move with the DS removed. 9good illustrations in that thread. thanx Fairtax for making me go look!

Fairtax4me Posted January 26, 2016 Share Posted January 26, 2016 Its basically the center diff isn't a locking diff. Its a limited slip design but unless the diff is damaged, it will not totally lock to engage full power to only one set of wheels (Front OR Rear). You can certainly drive it, but it will drive like an automatic with a high rpm stall torque converter until the center diff gets really hot. When it gets really hot it will still slip, and eventually the diff will be damaged in such a way that it basically welds itself. When you then re-install the rear driveshaft, the car will basically be stuck in 4WD, and the drive train will bind just the same way a 4wd truck of jeep would when driving on a road surface.
