center diff questions

[ASZRAEL1266]

I have a welded center diff and i want to get rid of it. I was wondering would it be possible to pull it out and replace it with a normal center diff or would i have to replace the entire tranny?

You can just pull the center diff out and put a stock one in

BTW, why do you want to go back to stock??

Thanks for the reply. I want to go back to a stock center diff becouse this welded center diff is costing me to much. I have snaped 4 rear axels I have a 4 bolt right now and i am not sure if it is strong enough. I daily drive the car and welded center diffs are not good for daily driving. Ihave snaped 2 of the axels just making U turns

You broke 3 bolt axles or 4 bolt axles?

That sounds more like an issue with your rear differential not the center diff. If your rear diff is in good shape it will "differentiate" the rear axles way before you snap one. If it is siezed you will overstess the axles.

I've been daily driving my welded center diff for four years on both the 3 bolt and the 4 bolt and never had any issues with tight turns breaking the axles. I've broken the 3 bolt axles twice on hard launches but that was in a straight line. I'm pretty sure the 4 bolts are strong enough as all the fast AWD DSMs use them.

The axels i broke were 3 bolt axels. As it turns out my center diff was not welded it was seized and it just callasped on it self and it is being fixed right now. I guess that is why i have been going through rear axels so fast.

Don't overlook your rear diff. Now would be a good time to check it out.

The center diff is inside your transmission and sends power to the front differential and to the transfer case. The transfer case sends that power to the driveshaft and then to the rear differential. The rear diff, through a viscous coupling, sends the power to the left and right side rear axles. The viscous coupling in a DSM serves the same function as a "Posi" does in musclecars. It tries to send equal power to each axle for equal traction and at the same time be able to allow each side to spin independantly while turning. If your axles are breaking while turning then the rear diff isn't allowing them to spin independantly.

I am not saying that I know your problem precisely just that you should look a little further because it doesn't all add up. Your axles are not directly connected to the center diff so I doubt that is the cause of them breaking. Food for thought... or investigation.

Yea. The rear axels i broke was on 3 diffrent rear ends. All of which were 3 bolts. The rear end in the car now 4 bolt is fine. I had it checked it is in good shape.

can a 94 center diff be used in place of a bad 90 center diff? does the spline count extend to this area?

 

[ASZRAEL1266]

I have no idea about that one man. Would be intresting to find out but i wouldn't want to try it out on my car incase it doesn't work.
