Dana 30 swap to disc

I want to get disc's on the front D30 axle on a mostly stock 76 CJ7. I was told, caus I'm a noob, that Dana 40 steering knuckles with disc's will bolt on. Is that right and will a Dana 44 off a Chevy be the same.

Any help/advice would be appreciated.

I am looking to do the same some day. What i found out so far is that Dana 30's came with dics on some years. If doing a junkyard deal you can pull the parts. Google it. There is a ton of info. I have also seen kits that you can buy to change to disc.

I used pre 79 GM caliper mounts and calipers with the stock spindles, 77- 78 jeep rotors ( 7/8") thick, I think. The thick ones.You must space the rotor outwards 1/8" to center in caliper.You could put it behind rotor, I put mine inside rotor under the inner race accomplishing the same thing.That's all.

Thanks zillla. I friend told me the same thing today. Purchased a used Lift with axles and disk on front. Any idea how big I can go on tires with a 2-3" lift? I've been told 33's but only 11.5 max. Seems narrow for that tall tire.

Sorry Wheelin. Still trying to figure things out. Thanks for the fix.

Thanks Dave will keep in mind.

Jim

Any ideas on gearing. I gave 2 sets of axles. One with 3.53 and one has 4.10 (currently on Jeep). I plan on doing some trail riding and some minor crawling but have to drive it to my riding areas. The 353's already have skyjacker 2.5 lift springs and disc so that's I need on but do I just put in the whole 353/lift/disc package or do I want to take that stuff off and put everything on my 4.10 axles. Will I be sorry I got rid of my 4.10's. Also I've only got a 3 spd tranny and am thinking 32'-33's. AHHH decisions decisions... Any advice.

Thanks Jim

Put the disc stuff on the 4.10 axle with 32s-33s.
