14 bolt hubs

okay soo im starting to cather up parts to put my jeep tj on 1 tons..today i bought a 14 bolt FF out of a 3/4 suburban..the axle is the second design 14 bolt.. my question is if a can run 1st design DRW hubs on my housing to narrow the axles wms width. im going to be converting to disc brackets and will be using weld on caliper brackets therfore the backing plate for the drums will be cut off. thanks

I traded my DRW hubs off of my second generation for a set of SRW hubs off a first generation and i am having MAJOR issues. brake backings are fine, but the hubs will not go all the way onto the axle b/c the journals are different. Tech section doesnt state this, so now i am learning the hard way. The hubs will not slide far enough on the axle for the spindle nut to go all the way on. I have the new style single nut with clip and metal key spindle nut set. Now I need a set of SRW second generation hubs........lesson is dont mix first and second generation parts.....If you want to sell your hubs let me know. There are plenty of DRW hubs to be found in junk yards.

Your problem is not mixing 1st with 2nd gen.... There are actually 3 different types of hubs. SRW and DRW are interchangable... the 3rd type is unique and does not fix on the axle that accept the other two. I've post pics on this a gazillion times.... if you want more info on it, search for the pics.

The third type is a cab and chassis but according to the 14 bolt bible posted on this site they are interchangeable. If there is a fourth type please give me a link to the data as I have not been able to find it through tons of searching this site.

From what i have read on the 14 bolt bible they consider DRW and C&C hubs to be the same..my main concern is weather i can run C&C hubs or even DRW hubs on my second genration 14 bolt to get a wms around 63-64"

I actually have a c&c axle and if you swap it will narrow the WMS width down like you want. Ruffstuff even makes bolt on caliper brackets for what you want to do. To avoid potential headaches I would advise staying within axle generations when looking for hubs. Let me know if you want to get rid of your srw hubs.

I don't have them any more, but yes. It narrowed it down by about 4". My axle is a 96. Sold my hubs for $50 and bought a set of first generation srw hubs which do not fit properly due to different journals.

On your DRW hubs..were the drums mounted behind the hubs itself? did u have to take the hubs and axleshafts off to remove the drums?

A "C&C" hub is a DRW hub.... same thing. The third "bastard" hub has a differnet bearing spacing dimension than the standard SRW and DRW hubs. I have 1st gen SRW hubs on my 2nd gen housing.... it's not a old vs. new housing thing.... it's a has to do with the 3rd bastard type hub that fits on it's own spindle which the housing a bastard as well. Every time I have encountered this hub type, it was from an axle that had the slip-on brake drums.

Oh and the Bible is wrong on this issue.... well not so much wrong as incomplete. The bible is a very nice collection of a LOT of data.... but there are some holes in the data. This hub issue is one of them.

ohh great well with my luck it looks as if i got the "bastard axle" so im assuming that the srw hubs that are on it now are the only hubs i am able to put onto that housing and there isent a way of narrowing the wms.

I have a C&C axle that have had DRW hubs with a slip over drum. Very common on the new finned style axles. So can i get a SRW hub designed for the slip over drum??? The person i sold my DRW hubs to says he is using them off of my C&C on his SRW axle. Where can i get a complete list of the types by part number?

Don't know.... hell, maybe there is a fourth hub out there too.

All I know if I have pictures of the standard SRW, DRW and the slip-on drum SRW hub. The first two interchange with each other and the last one won't.... different bearing spacing.

Ahh well i feel the same as you babyblue..i suppose im glad i havent started build the axle yet.. the 14 bolt bible should be edited to prevent this from happening to others.

well thanks for all the info and getting this all worked out.. now i suppose i shall began looking for another 14 bolt..but this time the right one
