Gyoas759 Posted June 29, 2007 Share Posted June 29, 2007 In need of some subaru wisdom. My 83 GL wagon runs and drives okay now. It has the 4 speed manual dual range tranny. Engaging in 4 wheel drive is no problem. It goes into the 4 wheel and lo range without a problem but when I take it back to two wheel drive, it makes a loud kaboom. Feels like the car should be dead afterwards but it keeps running. You have to push pretty hard to get the lever down. Any ideas on what the problem could be?

nipper Posted June 29, 2007 Share Posted June 29, 2007 Are all your tires the same size? Also manual 4WD is not meant to be used on a dry surface. You get torque bind in the driveline (especially with mismatched tires). The kaboom is the driveline unwinding. Dont use 4wd on dry pavement. nipper Link to comment Share on other sites More sharing options...
86BRATMAN Posted June 29, 2007 Share Posted June 29, 2007 ^^^^ What he said... If you must do it though, get into some loose stuff before you pop it out of 4wd Link to comment Share on other sites More sharing options...
Gyoas759 Posted June 29, 2007 Author Share Posted June 29, 2007 Sounds about right. I was testing it on pavement and I the rims/tires of the car are from 3 different subes. Good to know it's nothing unhealthy. Link to comment Share on other sites More sharing options...

Good to know it's nothing unhealthy. Best to only run in 4wd with four matched tires; at least, four tires identical (or very close) in outside diameter. a matched set is the most pragmatic way to be certain of this.

Skip Posted June 29, 2007 Share Posted June 29, 2007 Good to know it's nothing unhealthy. I am puzzeled by this statement?.... Well some say it's all fun and games until it really "goes kaboom!" which it will if you continue this practice. You can try reversing the vehicle to relieve the bind. Please get four matched tires (less than 1/4" difference in circumference) and do not drive on non-slippery ground. A dual range is a terrible thing to waste.

Gyoas759 Posted June 29, 2007 Author Share Posted June 29, 2007 Thanks Jerry, sure hope he reads and listens. Have read. Will listen. I was just under the impression that something was wrong with my transmission since it made that noise. Just glad that it was operator error and not my sube coming undone. Thanks all!

daeron Posted June 30, 2007 Share Posted June 30, 2007 That is great Skip! I love that statement. Too true. It's right up there with Cary Elwes' line (Wesley) in the movie The Princess Bride...

zyewdall Posted July 7, 2007 Share Posted July 7, 2007 A dual range is a terrible thing to waste. I know... and I have sinned. I have let two good 5spd dual ranges go to waste... sold one to a non-subaru person who junked the car a year later, and one was a friend's subaru that he abandoned when the timing belt broke, and the police towed it before I did.

BobBrumby Posted July 7, 2007 Share Posted July 7, 2007 Mine does the same thing all the time, hard to get out of 4wd, untill someone told to shift out of 4wd while going up a hill. I tried it and now I always wait to be going up a hill before i shift out of it. Link to comment Share on other sites More sharing options...
