Which Differentials do you have
« on: April 29, 2011, 08:13:37 PM »
  By the Faq's I seem to have at least a 44.  Will now need to look much closer and see if the tag is still there.  Know the rear is missing.

i think you mean axles, the diffs would be locked/open, or by brand (stock, arb, ox, eaton, auburn, etc)

i have D30/D35

most guys here would run an 8.8 or D44 in the rear and the D30 up front

Ok Axle and by the FAQ on it and my bolt patter my front one seems to be a 44.  Thought it should have been a 30 or 35.

you're right, stock YJ axles were D30 front D35 rear unless someone upgraded them (maybe previous owner). I don't think any of the YJs came with D44s, the Rubicon TJ had D44 centers but the tubes were same size as D30/D35 and the wheel bolt pattern was the same 5x4.5 (edit: and they had air lockers from the factory)

Its a 94 YJ as was said.  Was the second owner but I bought it in 94 with under 10,000 on it.  Was owned by a gal and sure she did nothing to it.

Will look in a few for the tag.

Should be D30/D35 with 4.10's The rear should have a rubber fill plug cap on the diff cover.

Its a 30 just had to look better.   But the tag really didn't say what it was.  Yep year had a rubber plug.  Needed to know so I could get the new gaskets.

None of the YJ's came with a D44 front as already stated. The D44's don't have a central disconnect on the passenger side of the axle housing. They have a one piece inner axle. The YJ's and some XJ's had a 2 piece inner axle with the motor assembly.

I'm curious where you saw this in the FAQ?

There's a Waggy D44 with vacuum disconnect... 

Oh, and I run Super D35 and Super D30 with ARB on both ends (of course, after the last trail run, I killed the ARB compressor, so now I have open diffs until I fix it!)
