Re-Gear help

[Hedsic]

I was hoping someone on here could give me some insight. Either posting here or even IM'ing me or whatever.

I need to regear. I want to run 265's really bad. Regearing is the only way I can go to that size without messing something up.

So far i've had zero luck finding any place around here that will do a regear. I found one place that said they'd do it for about 1400+ not counting parts but than I was told no they had never done that on a KJ so they'd pass. I asked around some local forums and it appears other guys had to go out of state just to get it done on their non KJ Jeeps. I can only imagine the cost with all of that.

Is there any possible way a non mechanic such as myself could actually do this job? I have no mechanic background really. I learn what I know by doing it and following how-to's and directions to a T. No how-to exists from what I found for a regear. One guy in the local Jeep club said he could help me with setting the backlash. He said that should be the only hard part about it all. I don't think he realized at the time it's for a KJ.

Is this just a job that should be left to someone with experience and not taken on by a how-to guide and a can-do attitude?

Hoping to get some insight from others on here. I live in Des Moines, Iowa so basically I'm near nothing lol

From my experience, diffs aren't that hard really. However you have to have a pretty good grasp of what is going on, how to do the measurements, and the tools to do it. You have to have a dial indicator, 1/2" torque wrench of good quality, and a 1/4" torque wrench to measure the preload on the pinion. When tightening down the pinion nut to set the crush sleeve, it takes a lot of oomph to do it. Some 1/2" impacts won't even do it, and the ones that do, it takes a lot of finesse to not go too far and ruin a crush sleeve. The Chrysler axle will require a spanner socket to adjust the side bearings on the carrier as well. As far as shims, etc, normally if you use the same size that came out with the old ones, you're ok. The biggest variance is in the diff housing, not the gears or carriers or bearings IMO. The front diff has to come out to do it as well which is what may scare a few shops. If you were out here, I could do it, though I suggest if you have open diffs, now is the time to upgrade to DTT or ARB's

I had a shop in town do mine a couple of years ago. We considered doing it here, but it's my DD and we don't have the correct tools. I was charged $600 total for both axles (I supplied all the parts, however). If you lived closer, I'd give you the name of a couple of shops that could help you.

I've found (and have heard others say the same) that it's better to source your own parts, and then take them to someone who will do the labor.

Labour should be about the same as total cost of front and rear gears with master install kit for each.
I had 4.10's installed on mine for about $1600(plus tax).
4.56's require the steel front diff(another $1500) and some modding of the ring gear in the rear.
The front diff needs to removed to do the change.the rear can be done inplace.
Make sure you get D30a gears for the front,not D30.

That's about all I can contribute.

Good luck

Labor wise, it looks around 5.9hrs for the front, and 3.5hrs in back. So easily $900-$1k in labor plus fluids and parts.

Regearing is best left up to the folks who do it all of the time.
I used to do 44s/60s/ 9 inch fordsall the time, but i had the tools, and was in practice. Its not something for a first timer to just jump in and do or at least my two cents
You do know there are 4 cylinders out there with 4.10s in them and with a little luck can find them.
We did TwoBobs that way here in my garage a couple of months back and getting ready to do another guys ( won't tell whose it is yet) in the next week or so. Not hard to do, didn't even pull the brakes etc Fronts as easy as the rear
You can also look for a Jeep tech who may do it on the side , I had a 4 cylinder front and the guy threw in the rear gears and also installed the front diff for me for less than the cost of the rear gears alone
keep looking you'll find someone

Total I had about 450 in everything I think

Ooooh I hope it's me

Just checked the name...........NOPE no Luke on the list :Nonono::laughing1:

As a former des moines resident, I don't know of any place right off hand you could try. There wasn't many decent places when I wrenched there back in the 90's.

Yeah i just assumed being Iowa i wouldn't find a 4cylinder in any of the junk yards to use. Guess i should check around before giving up there lol

Plus side is that it seems most all of the 4 cylinder 4 wheel drives are fairly low mileage. Most found are in the under 80,000 mile area
Even if you had to have the front diff shipped in it most times would be resonable

 

[tjkj2002]

Heck I know how to re-gear diffs(granted more familiar with top loaders) and I pay someone else to re-gear.Granted I did do the re-gear to 4.10's myself but cheated with a brand new D30A with 4.10's,just switched the carrier out to a DTT and the 8.25 is pretty simple if you have that stupid 4' long socket and those pesky ARB O-rings are a royal pain in the rear.I did pay to have my new axles geared to 5.13's though and install ARB's.

Damn it! :angry94:

 

[yellocoyote]

You can always check local and regional yards by going here: www.car-part.com

 

[Hedsic]

Wasn't able to find anything on there. Once it gets warmer I'll hit up a few yards around here.. Is there a thread that has a list of all the parts I need to buy? Found a few threads that had some lists but then there are posts saying the list is wrong etc Couldn't find a definitive accurate list of everything needed for the regear.

 

[CactusJacked]

Check flebay, there's quite a good number of Liberty's getting parted out. You might find something there that may make it worth taking a mini road trip to pick up.

 

[tommudd]

Front is easy
only Dana Spicer makes the 4.10s for the D30a
but be careful since several gear places list the regular 30 gears as fitting the 30a
rear pick a good set of gears for a 8.25 and you're golden. Some of the cheaper ones aren't worth installing
Plus need install kits for each end.
jeepinbyal has everything you need
Trail Quest in Plain City Ohio is another good place to deal with and know the difference between a 30 and a 30a
