picked up a cj5 and have axle questions

ok im new to the cjs. ive built 3 yjs, 2 tjs and have a stock jk as my daily driver. the cj5 seems really narrow and i would like to widen it a little to make it a little more stable. is the axles out of a yj to wide or did another cj have wide axles? would also like to put disc brakes on the front too
Edit: jeep is 100% stock and original 74 model

YJ axles have the front diff on the wrong side and usually a weak Dana 35 rear. '82 to '86 CJs have wider axles and front disk brakes, but usually worse gear ratios than what you probably have. You should currently have 4 wheel drum brakes with a Dana 30 front and a 44 rear. Yes, they're narrow track, but give them a chance before you ditch them. Think of where you can fit with it that narrow.

that is true. im worried about rolling it mostly. but the brake upgrade is a must. will the brakes be an easy swap? techincly i should be able to get just the knuckels off a 76 and newer cj right?

One alternative is wheel spacers, whcih can get you another few inches on the track. Just make sure you buy some quality ones and not the eBay ones which are generally lower strength.

i was thinking about useing wheel spacers. one reason i was thinking of changing axles is that ive always heard that the cjs were bad about breaking the axels. is this true?

I am running a little older CJ but I put Scout axles under it. They are disc up front and both front and rear are dana 44's. The only downfall they are a bit higher gear ratio, but they will work out fine.

intersting, never thought about scout axles. a 44 in the front would be nice to. how much wider are the scout axles?

If stock, you should have a Dana 44 30 spline rear. This is plenty strong for a CJ unless you're getting crazy with giant tires or lots of HP.

A Scout 2 Dana 44 front end is aabout 2 5/8 wider
1 some people outboard them
2 I had mine cut and the knuckles rewelded back on at 10 degrees for camber.
then I got a chromolly shaft had it cut and resplined to fit.

Scout 2 axles don't have enough camber so you have to rotate the knuckles.

I think the main question for axle choice is your planned use for the vehicle? A 99% DD doesn't need much for upgraded axles.

I've had the stock narrow axles under mine (78 CJ5) since I bought it, and DD it 90% of the time. I have driven it thru winters with Ice, snow, rain, sun. Drove it the ten hours to Chat, TN and then back, and never once feared it tipping or rolling. Under normal use, I don't think that would be an issue. Just remember off-camber angles are not good and avoid them!

I have drum brakes on Puthijeep and they take a little getting used to but are fine for DD and wheeling. Unless I was going to us eit for long highway high speed trips I would not go to the bother of changing them.
