Dana 30 advice

Hey guys I've got a high pinion 30 in a 94 yj.
4.88 gears and lockright in it. I pulled some guys out the mud and shelled the cross pin which took everything else out. So rebuild time. Question is since it got carrier locker and r/p do I rebuild with Detroit or is it gonna happen again. I just recently went to 4.88s and currently running 35s. May jump to 37s someday.
I'm not hard on pedal and have had the lockright in it since 1998.

If you say new front axle give me opinions on which one and why. And I'm recently divorced with three girls child support so money is tight!!!!

If you stick with the D30 it's going to again with 35's and certainly with 37's.
Please, don't spend money polishing a turd. Find a 1980 or later Waggy D44 and use that.

You should be able to make a 30 live on 35s especially in the mud. If money is that tight, throw in a new carrier with a lunchbox locker. Make darn sure the install is done correctly (bearing preloads, etc.).

That being said, if you go Dana 44, I wouldn't waste my time with anything other than a High Pinion 44.

Detroits...meh. ARB would be my choice.

X2 these can be had cheap if your still running the 35 rear maybe it's time for an upgrade on both ends.

If it already broke once, i think it's swap time. by the time labor and parts are done, you're well on your way to a decent hp44. I second the early 80's waggy 44.

build a waggy 44, spool, lockouts, and gears.

As atblis mentioned I have several rigs running 30's on 35's and they are not babied in the slightest. Were you pulling out the other rig in reverse. If so that is why you broke it. If money is tight I would rebuild what you have for under $500 you are back on the trail.

Then as funds allow begin building a 44 and swap when everything is complete, sell the 30 for $200 buckets and keep going.

x2, run a Jana K4 kit if you are worried about the gears and run a full case locker.

If you drive wisely the hp should be good. A guy I wheel with has a hp 30 in his TJ with 37" tires. With the super 30 kit and an ARB. He's been running it for 8 maybe 10 years and runs lots of trails each year including 3 or 4 trips each year on the Rubicon

There are so many pros to going 44, lockout hubs, wider range of gears, bigger stronger gears .Go with a waggy 44 and don’t look back. Just remember to avoid the vacuum disconnect axle they made for a couple years in the early 80's I want to say they were made from 82-84. The 80-81 were non disco as were the 85 up axles.

On the cheap, 35" tires, a hp30 will survive with a locker and common sense.

Would probably go with a selectable locker for a YJ. I know several people besides myself that seem to keep 30s alive, with a front locker and 35s.

Have to remember that it's a 30 and treat it as such.

I run a 30 but a waggy 44 is much more desirable since he's starting from scratch.

I suppose if I stumbled accross a 44 set up exactly the way I wanted it, I would go for it. Maybe a set of JKs or TJ 44s at the right price. Otherwise from a cost, time and benefit ratio, I can't see spending the time building a 44, where I would be replacing U joints, axle shafts, getting the drive shaft cut to length etc etc etc. If, i was going down that road, I would look forward to a Dana 60s, where the time and money invested would allow for 37s, and down the road 40s, where the bearings, knuckles, R&P housing are all more durable. I haven't found anything cheap about building an axle the right way.

Rebuild the 30 n next time use ur winch to pull ppl outta mud. I beat on my 30 like its my job (same set up as urs) n never a prob in 3yrs. if u have to pull someone at all DONT do it in rev. Takes the strength of ur hi pinion away. FWIW I mite someday swap a 44 in but never a waggy. It's Ford hi pinion or nothing. Lotta work n $ to not constantly have to worry bout my dshaft getting hammered.

That gets my vote. I did the same thing, pulled someone out in reverse and cleaned the ring gear off. Otherwise, offroading I beat mine hard on 36's and an aussie and it stood up well. I did upgrade to the 95 shafts with the larger wheel joint. Good Luck
