1 1/8 pin vs 1 1 1/4 pin Dana 18 case

Ok my dana 18 has been getting worst since my windrock incident ,getting louder and leaking more R) . The front yoke has gotten a little play in it now. So I figured I need to rebuild it ,but one of my buddies offered me a case so I wouldnt risk having my jeep apart when Uwharrie trip came up. Well he had a few to chose from so we took off the easiest one to get to and popped it off . All of them where on 60's model jeeps so I didnt even think about the shaft size after we got it out he remembered that tranny and case had came out of a 2a . So we checked the shaft size and sure enuff it was a 1 1/8 shaft . But the case looked really good the gears looked alot better then mine . So think Im going to run it, from what I remember theres no lost of strength just LONG term wear like 20,000 - 30,000 miles. Ive had my jeep for 3 years and havnt put 3000 miles on it so the milage durablity problem isnt to big of a concern R) R) . Or do yall think I should go and rebuild the 11/4 shaft case?

 

I don't know what your buddy is charging you for the other case but if it's cheap I would try running it. If and when it gives you any problem then I would rebuild the 1 1/4" case. At 1000 miles a years that could be a long time. At least that is what I would do.

Ummm the same buddies always charge , free R)

 

Dunno ??????

 

If Im looking at it right this case has a 3.125 hole , the 11/4 shaft case is still on the jeep. Whats the diff and which is better?

 

The gear difference is that the old models were 2.43:1 while the later geared ones were 2.46:1.

 

Just to add to this old post; I have had both. I found no difference in strength or durability. The only thing that I believed (and this may not be correct, just my perception) is that the 1 1/4 pin case with the needle bearings was a little quieter than the 1 1/8 pin with the roller bearing / cage bearing arrangement. I would run either one of them with confidence though.
