wide trac front d30 vs narrow trac quad
i was wondering if theres a difference in the 83 wide trac d30 front axle and a 79 d30 narrow from a quadra trac i was thinking of leaving the wide one in and keeping the hubs locked then use spacers in the rear to get the width with the narrow one. also theres a rubber hose comming out of the top of the differential is that for a locker or just a vent. sorry for the stupid questions ill be an expert when im done i promise

i think they are the same, ive been eyeing a wide trac front and since mine is a quadratrac to just using spacers in the rear, interested in seeing if anyone has done anything similar

The hose coming from the axle tube is most likely the vent hose. Follow it and see where is ends. The vent line will end a a small plastic breather. As to you first question, if I understand what your looking to do. It would help if we know what you have,(Jeep type, Yr., drivetrain, etc.).

It's not clear what you want to do.
Are you talking about putting a wide track axle in a CJ that uses a quadratrac transfer case?
Since you're Jeep info isn't filled out, we can only suppose that's what you want to do.

If you're talking bout putting the WT into a CJ with a quadratrac, I would use the drive flanges from the NT so you don't have to worry about the lockouts.

Sounds like the OP wants to run a wide track front axle and a narrow track rear axle, using spacers to make up the difference. At least that's how I read it.

True, but it looks like he's talking about mixing quadratrac and standard axles.
His post is a run-on sentence and it's not clear if he wants to put the wide-track front axle in a Jeep with Quadratrac or put a Quadratrac rear axle in a Jeep with a standard transfer case (e.g. Dana 20 or Dana 300).
Any answer that's limited to his question about width/compatibility alone could be accurate but incomplete because of his intended usage.

A shining example of why proper grammar is still important. Nobody can figure out what the OP is asking.

sorry about the spelling and grammer, i speak well but i lack in the written language i know. my question was in the end im looking to use a 83 cj7 d30 front axle in a 79 cj7 quadratrac then space out the rear. i got a frame with the axels on it and want to use the front just so i dont have to change it, and also the condition. it would mean id only have to change the rear one to the new frame. one axle in the quadratrac was replaced with a regular one because the hub striped so it has a lockout on one hub already so i though it was fully possible to use the regular axle assembally and keep the hubs locked aslong as there the same gearing

The wide-track front axle in a Jeep with Quadratrac transfer case will work. Just keep the hubs locked or use drive flanges.

if you unlock the hubs you will blow the quadratrac transefer case. Ask me how I know

Are the gears the same? Might not be able to use 4wd.

thanks for the responses, i kinda like the idea of the locking hubs so if i ever need to tow it it can be picked up from the rear ill have to check the gearing but were there any changes of the stock gearing between them

Very likely.

The gears have to match. That's a full time 4WD transfer case.
If the front axle isn't engaged, you'll burn up the transfer case. AMC's Borg-Warner 1339 Quadra-Trac transfer case included a clutch-pack limited-slip center differential.
The differential could be locked to provide equal power output to the front and rear for true four-wheel-drive performance but that wasn't the normal mode.
