All the J20's and any of the 3/4 ton trucks I've ever seen were 8 lug. FC excepted. I have several J20 axle assemblies as well as a couple J20's if anybody really wants one. I've got one of the 5 x 5.5 semi float ones in my garage ;) It actually says 60-2 on the casting as well. They are not easy to come by. We found it for $100 with a WMS/WMS measurement of 65.5". If you want I can take a picture of it tomorrow for you. DD on pirate runs one as well: http://www.pirate4x4.com/forum/showpost ... stcount=13

In 'design' it IS stronger. In reality, it is not. Of all the 30 spline Dana 44 shafts I have personally seen break, never have I don't recall the flange of the axle shaft ever failing. Keep in mind it tapers up pretty thick for the bearing to be pressed onto the shaft. The thin section near the splines is usually what goes. This is IDENTICAL on both the Dana 60 full float and the Dana 44 semi float so there is basically no gain (othe than weight) to go that route. This is usually how the 60s and 44s shafts fail: FWIW, the budget 'Pirate' crowd who are into big power, big rocks, and big tires, all run to either 14 bolts or Dana 70s because of the significant shaft strength and they skip right over the Dana 60. They also run Dually axles because the width can be as little as 63" and they can run the axle stock on 40" tires for $150 out of a junk yard ;)

I don't beleive any effort to convert the MJ/XJ to full width is worth the effort. The rear dana 60 on the J20 is still 30 spline (the same as our Dana 44s). If you can find one, if you can get a 1970-ish J20 rear, it has a WMS of a mid size (65") and comes in a non C-clip 35 spline axle with 5 x 5.5 bolt pattern. A strong stock axle wiht a reasonable bolt pattern and not too wide. Just need to find a front to match.

It is my understanding that every jeep that has been made has a 2 letter designation. MA - The original prototype Jeep submitted by Willys-Overland for the military contract in 1940. "M" stood for "military"; "A" for the first model. MB - The revised model first mass-produced by Willys-Overland for the military in '40-'45?. "B" stood for the second model. GP - The original prototype Jeep submitted by Ford for the military contract in 1940. "G" indicated government issue; "P" indicated an 80" wheelbase reconnaissance vehicle. GPW - The revised model first mass-produced by Ford for the military in '40-'45?. It is virtually identical to the MB (the "W" stood for "Willys' design"). M38 - aka MC - The next generation military Jeep by Willys ('50-52), similar to the civilian CJ-3A. Like all of the above models, it was a flat-fender style. M38A1 - aka MD - Basically the military version of the CJ-5 ('52-'71). Unlike the CJ-5, it had the front shackles behind the springs instead of up front. M170 - Similar to a military version of the CJ-6. 4155 of them were made in the mid-50's and early-60's. CJ - The first civilian version of the military-inspired short-wheelbase Jeep, made '42-'86. Encompasses everything from flat-fenders to Scramblers. Like many other early Jeep designations, "CJ" actually stands for something: Civilian Jeep. Various numbers followed the CJ designation, indicating different body styles within the CJ line: CJ-2A - A flat-fender, very similar to the military MB ('45-49) except that the headlights bulge out of the grill instead of being inset. CJ-3A - A flat-fender, very similar to the military M38 ('48-53). CJ-3B - A flat-fender, the top of its hood sits 4" higher above the fenders than the 3A to clear the new F-head engine ('52-68). CJ-4 - Only one prototype is known to exist. It was discovered in 1997(?), still in the hands of its second owner. It looks like a 50/50 mix of a CJ-3A and a CJ-5, with only slightly-rounded fenders. CJ-5 - The civilian version of the M38A1, but with the front shackles under the bumper like most other models. 81" ('55-'71) or 84" ('72-'83) wheelbase. Front fenders are rounded like all subsequent short-wheelbase Jeeps. Easily distinguished from the CJ-7 by a small doorway with a rounded, sloping rear edge. CJ-6 - Essentially a CJ-5 that was stretched 20" ('58-75), intended for use as a small pickup. CJ-7 - A compromise between the CJ-5 and CJ-6, having a 93.4" wheelbase (like the YJ and TJ). The body tub is very similar to the YJ and TJ, but the rear wheel wells are round instead of angular. Made '76-'86. CJ-8 - Also called a "Scrambler." Similar to a CJ-7, but with an extra 10" of wheelbase and an even longer rear overhang. Like the CJ-6, it was intended as a small pickup, but never really found its niche. Only 27,000 were made from '81-'86. Commonly seen with half-cab tops that surround only the front seats. CJ-10 - A more truck-like Jeep built mainly for export from 1981-85. A small number were also sold to the US Air Force for use in pulling aircraft around runways. These Jeeps had very stout drivetrains compared with their smaller brethren. Easily distinguished by the square headlights in the fenders and the 10-slat grille. YJ - The original Wrangler, made '87-'95 (though production actually continued into March of '96). Rectangular headlights make it the bastard child of the of the short-wheelbase line. Rear wheel wells are larger and more angled than the CJ-7, but otherwise the two are visually quite similar. TJ - The second generation Wrangler, made 1997-2006 (actually began shipping May of '96). Round headlights, coil suspension, and a much more car-like interior distinguish it from the YJ. JK/JKL - The third generation Wrangler, introduced in 2007. It's somewhat larger than the TJ, and has a rounded windshield and body panels. JK is the 2-door version; JKL is the 4-door. SJ - The full-size Cherokee ('74-'83), Wagoneer ('63-'83), Grand Wagoneer ('84-'91), and J-truck ('63-'87). In 1984, Jeep introduced the down-sized XJ and started calling them Cherokees and Wagoneers, leaving only the Grand Wagoneer in the SJ lineup until its demise in '91. M-715 - A 5/4-ton military pickup built '67-'69. It somewhat resembles a J-truck (SJ), only bigger and badder. The M-725 was the ambulance version of the M-715. XJ - The down-sized Cherokee ('84-'01) and Wagoneer ('84-'89?). It was (probably?) the first Jeep to use a unibody chassis. KJ - The Liberty ('02-present), which replaced the XJ in Jeep's product lineup. ZJ - The Grand Cherokee ('93-'98), which replaced the Grand Wagoneer (SJ) as Jeep's luxury cruiser after a 1-year hiatus. Though much more aerodynamic than the SJ, it's obviously less rounded than its replacement, the WJ. WJ - As the more bubble-shaped, aerodynamic replacement for the ZJ, it continues the Grand Cherokee name ('99-04). WK - The third style of Grand Cherokee has a more angular design than the WJ and also joins the Liberty in having an independent front suspension ('05-present). ?? - The Commander was introduced as the big brother of the WK, offering 7-passenger seating and the 5.7L Hemi V8 ('06-present). ?? - The Patriot is a compact, 4-door, crossover SUV introduced in 2007. It's bigger than the Compass, falling somewhere between the Grand Cherokee and Commander. ?? - The Compass is a compact, 4-door, crossover SUV introduced in 2007. It's smaller than the Patriot, but slightly larger than the Liberty. MJ - The Comanche pickup ('86-'92). It shares much in common with the XJ of that era, including its front unibody chassis. It replaced the full-size Gladiator and J-truck pickups of the SJ era. DJ-3A - Dispatcher (postal) version of the CJ-3A, made '56-65. Only 2-wheel drive versions were available. DJ-5 - Dispatcher (postal) version of the CJ-5, made '65-8? by Jeep and then AM General. Only 2-wheel drive versions were available. A DJ-6 (long, like the CJ-6) was also made from '65-68. VJ - The Jeepster ('48-50) was an attempt by Willys to spice up their vehicle lineup. 2WD, 72hp, and poor marketing doomed it to be discontinued after less than three years. C-101 - The Jeepster Commando ('66-73) was an attempt by Kaiser to compete with with the Bronco and TLC. The C101 was part CJ and part Wagoneer, advertised as a "happy combo, racy and rugged." This time around it had 4WD, and came in convertibles, hardtop wagons, and half-cab pickups. FC - Forward Control pickups, with the cab directly above the engine. Made '57-'63.

It can be done. It is not fun but completely doable. The bigger the lift the easier this is to do as well.

It is called a hub. The axle runs on spindles (as opposed to our 4x4 MJs coming with unit bearings) and the spindles are large. It is the hub that covers the spindle, outer axle shaft. FWIW, most of the late model waggy axles came with drive slugs and no manual locking hubs as they had full time 4wd.

'lock out' be a problem? Please elaborate.

no they are not FYI, the MJ has bigger wheel wells.

But it is still completely usable. Just need to relocate the stryker ;)

4 door cherokee doors work on the MJs. 2 door XJ doors do not.

The front waggy is definitely a good set up for wheeling on 35s but the pumpkin is a little big for 33s (and the lift to accommodate 33s). It is not impossible to fit but just way tighter under there. The rear waggy axle is NOT a good axle for the MJ. There are a couple of issues with it. The biggest issue is the width. It is VERY narrow and with the EXTRA WIDE rear frame rails on an MJ, guaranteed rubbing and interference with angled suspension travel is a must. The easy fix is wheel spacers on this but people will have their opinions on wheel spacers.. The other issue is the axle shafts themselves. They used a couple of different sizes over the years for the rear axles so finding spares can be fun. Basically you have to go to the yard and pull shafts and measure them. The third issue is the lack of aftermarket support. It seems that even the SJ guys dump these rears for other options. The shafts are only 30 spline and require custom lengths so they can get expensive. Currie charges $460 for a pair of shafts (including the bearings though). Please note it is VERY simple to convert a front waggy to 5 x 5.5" bolt pattern (Small bearing Chevy spindles and a set of ford rotors). When it is converted to 5 x 5.5" a standard MJ Dana 44 will match up quite nice with off the shelf aftermarket shafts with the same bolt pattern (i.e. Alloy USA).

Thank you for clarifying that. I had thought so but I wanted confirmation. :cheers:

I too would like to confirm that the sensor on the head next to the fire wall is, in fact, the guage temp sender only or for anything else..

What is your definition of rock climbing? What size tires are you looking for it to handle? You going Hammer style: Or basic rocks:

Junk yards and learn more about what will work from XJs. :thumbsup:

OK. If you say so. The XJ plates don't work on the 8.8 swap :shake: 8.8 axle tube is larger axle tube at 3.25"

You don't need the XJ spring plates. The MJ ones are fine. If the stud bothers you you can revers the sides and put the stud in the front or you can cut off the stud with a cut off wheel. this is true but if you did have some XJ plates sitting around it would be silly to modify the MJ plates. I have a bunch of XJ parts cluttering up my garage to its my first instict to try and use some of that junk. even if you didnt have them, theyd be super cheap at a junk yard with no modification required. i wouldnt make a special trip for them but if you were there... I think the word 'modify' is too much for what you have to do here. It takes like two minutes to cut off both studs with a cut off wheel as opposed to driving all the way to a yard and buying a set of cherokee plates.

Axle all day long. Get the longer travel in there without compromising clearance Ruff stuff has these: http://www.ruffstuffspecialties.com/cat ... -p-97.html Also Currie has these: http://www.currieenterprises.com/cestor ... px?id=1824 I use one similar to the Ruff Stuff's on my rear axle:

That is death wobble. Other things to check: UCA and LCA bushings Wheels Balanced? Track bar bushing tight? Track bar itself tight on the chassis?

I know this might sound odd but I have been here in LA for 15 years and I miss all the storms and seasons of New England being born there. We don't really ever have any good storms out here :( I am glad everyone is ok though.

X10000 They are not even needed offroad.

I'd snag the axles. They are actually pretty nice and I beleive you could be getting the rear electric locker which you'll need to wire up but other than that just make some brackets and you'd be sitting pretty.

I have heard of good success with a clutch fan from a grand cherokee. Unlike hornbrod, I prefer the mechanical fan and the auxillary electric fan out of a late model XJ.

Notes: Pretty much the whole vehicle has been changed from when it was first aquired. It used to be a 2WD with a Peugot Manual and is now an automatic 4x4. The frame rails have been plated as well as the drivers front wheel well. The interior floor has been cut and rebuilt to make room for a transfer case doubler and a completely flat belly pan. There is a home made fuel tank skid. Custom exhaust job. Traction bar. Custom rear bumper. Custom hybrid cage. Sits currently on 37" MTRs with alloy beadlocks. 7" custome 3 link lift with Bilstein suspension. Rock lights. Floor mounted transmission shifter. LOA rear with a modified OEM MJ leafpack. Much Much more. Interior color is black and has a bench seat. Exterior color is now white but I am unsure as to what the original color was (dark charcoal?). Mileage is to be estimated at 160K but the spedometer had stopped at 122K on the chassis Current owner: Me. Avery and it is in my back yard :cheers:
