What are my axle options?

I have a 1987 Wrangler YJ. Iím thinking I need to do a locker. What would be my options? What suggestions does anyone have? Should I just do a locker with the stock axle or do an axle replacement. Really looking for some wide open suggestions hereÖ

Thanks,
JC

Don't lock the D35 if that is what you have. It is a weak link---find a Ford 8.8

Thats right I wouldn't lock the D35 unless your running stock drivetrain and 31's or smaller. Beyond that your going to want to upgrade to an 8.8 or better.
Your best bet is a rockwell 5 ton.


Here are a few locker brands
Lock-right
Ox
Eaton
Detroit
ARB
Powertrax
Auburn
Tractec
Aussie

and here are a few axle options
Dana 44
Ford 8.8
Ford 9"
Dana 60
Corporate 14 bolt
Dana 80
Rockwell 2.5 ton
Rockwell 5 ton

The possibilities are endless.

If you don't have the $1k+ to replace the rear axle right now. Put the locker in the front, but trash that D-35 ASAP. The front D-30 axle is good up to a 33" tire, they hold-up to 35's-37's with chromoly shafts.
A later model 8.8 will give you disk brakes and it's stronger than a D-44, but you'd be limited to 37" tires.
The chevy 14 bolt is bomb-proof, the big pumkin costs ground clearence, but I've never heard of one breaking.

$1000+ to change a rear end???? I found a great ford 8.8 from a wrecking yard for $250. I inspected it real good, replaced the brake calipers, pads, rotors, e-brake shoes, and brake lines for about $200. Spring perches were $20. So I did my 8.8 swap for just under $500.
I did a lot of calling around here and the average price was about $275.

Ya if you went with a locker instead of the LSD, $1k would be about right. I guess I never really added it ALL up before. I just have in my head $250 for the rear end, and the rest is gibberish. Maybe thats why I'm so broke all the time. No, wait "It's a Jeep Thing".

is the 8.8 a direct swap as far as width? i know u have to do your spring perches and center it up but other than that is it an easy thing?

Ford 8.8 is the perfect width and same lug pattern as the front. It is one of the easiest upgrades to do. Don't forget to match your front and rear gears up.

The 8.8 is about 5/8" narrower on each side. Not enough to notice.

just make sure to get one out of an exploder. the f-150 ones will be wider and have the wrong lug pattern

Well if it doesn't have the little tag on the diff cover and you really need to know the gear ratio there is another option. Pull out the ring and pinion, count the teeth on both the ring and pinion and then divide the pinion/ring and it should give you your ratio.

I had to do this in class last thursday. Teacher gave us a ring and pinion and told us to figure out the gear ratio. I was right too!

don't pull the ring and pinion out. you don't have to do that. pull the cover off, and you can count the teeth on the ring, and the pinion and then divide.

besides, replace them both and upgrade your gears to 4.10 or better.

95 to 2001 ....

and they can have disc brakes or drums for all those years.. but it is harder to find one with drum from 98 to 2001 exploders.

from 95 to 98 the disc brakes was a "option" but ford produced most with disc. ...."more money in there pocket".

Get one with disc brakes! Factory axle ratio's option are....

6 cyl,, 3.27 ratio
6 cyl,, 3.55 ratio
6 cyl,, 3.73 ratio
6 cyl,, 4.10 ratio
8 cyl, 3.55 ratio
8 cyl, 3.73 ratio
8 cyl, 4.10 ratio

these are all from 95 to 2001 exploders.....all years where also availible with a LSD or open.
