gears broke in rear end

so had a load clicking noise coming from the rear end as i was driving the other day. finally opened rear dif todays and find one of the smaller gears and broke in half and teeth missing from a couple of the other gears. i am not very smart with stuff like this but have a buddy that is and is willing to help. what would you recommend getting just new gears or just a whole new rear end. its from a 89 yj and looked up vin and has a dana 30 is what i have found? help please

Matt

i and just about everyone else will recommend going to a junk yard and picking up a ford explorer axle with disc brakes for about $250 and swapping it in. then you wont have to worry about your rear anymore

Agreed^^^

Find out your gear ratio and match it with the new axle. Some will say that replacing the broken part is all you need but I would feel inclined to slap them on the back of the head because they have forgotten their thinking caps. The question is not where to find the replacement part that broke but why it broke in the first place. Your axle tube is possibly bent and your entire rear end may be toast. And not good toast but more like s*** on a shingle but not edible.

Whatever.

Match gear ratios and never put a dime into a Dana 35

While the swap is a big improvement, it will involve some fab and set up.

If that is out of your current range you may be in luck. Sounds like you broke a couple of spider gears. If there is no damage on the ring or pinion you may be able to simply change out the broke gears. It is an easy process if your friend has a little skill and knowledge.

Welcome to the forum.

I suppose what you're going to have to do is determine what you want to use your Jeep for, and what you have available locally as far as junk yards, Jeep clubs, how much money you care to spend, and what tools you have at your immediate disposal as well as your level on the Wrangler Wrenching Scale of Mechanical Competency. If you need least expensive, get you back on the road, find some new spiders and grit your teeth, it may work just fine. If you are a mechanical neophyte and have to repetitively intone the mantra of "lefty loosey," are a mouth breather and only own a hammer, it will be more of a challenge. You can find a replacement D35 in a JY and just bolt it directly in, smile and then go drink beer. Just make sure you get a ratio matching what you have up front, or there goes any savings when you grenade your T case first time you put it in 4WD. You could of course get both front and rear axles from the same Jeep in the JY, so long as you can find the ratio you're pleased with.

You can graft in a Ford 8.8 as others of the cognoscenti have suggested, it requires a bit of skill and some welding; Junkyards are full of them in Ford Exploders, Mountaineers and you'll have to come up with a custom driveshaft likely. If you don't have local laws about tires being totally covered, you could find late 70's F250 etc and go full width with some awesome axles, Or you could score a pair of custom Currie axles or even some Rockwell planetaries if you are independently wealthy and just want to spend money and boost the economy. Tons of options.

Check local Craigslist postings, etc, I bet you can find a ton of choices, and let us know how it turns out.

Here is a great article on the 8.8 to help you identify and choose correctly.

Also OP, just want to make sure you clued in on something Ophi59 touched on, your rear axle is a dana 35, not a 30. The dana 30 is the front axle.

Certainly.

Um, what's another word for "thesaurus?"

Day after I bought my jeep 6 years ago, the rear axle gears locked, u-joint broke and little pieces of metal were all over the road. I took it to dealer, I know, they charged me $2500 for one they pulled out of junkyard and put new gears and axles in...would not go that route again, can save a lot of money doing it yourself

For $2500, I could build a VERY nice set of axles.
