86ComancheXNate Posted January 31, 2011 Posted January 31, 2011 I'm debating on whether or not to put a locker in my rear axle. Right now I'm running a 2.8 V6 with and AMC20 rear with 4.10 gearing running 31x10.5's. I'm planning on doing a drive train swap for a better engine and to get 4wd, but I'm waiting till I can afford a donor cherokee. for the time being I've been tossing around the idea of putting a locker in the rear? any suggestions?
jimoshel Posted January 31, 2011 Posted January 31, 2011 I'd save my money so I could get the donor sooner.
Dirteatr717 Posted January 31, 2011 Posted January 31, 2011 Save it and if your replacing axles find a donor with a posi rear :dunno:
HOrnbrod Posted January 31, 2011 Posted January 31, 2011 Have you made the effort to check prices and/or availability on an AMC-20 locker? :eek:
cody4359 Posted January 31, 2011 Posted January 31, 2011 ive found 2 chrysler 8.25 29 splines for $100 each and i put disk brakes from a zj on them for $40 from wreckin yard. lookin at gettin an aussie locker and from the webstite their $300 but out of stock. overall fairly innexpensive and will put up to my abuse with 33s
Eagle Posted January 31, 2011 Posted January 31, 2011 Save it and if your replacing axles find a donor with a posi rear :dunno: Why would he replace an AMC 20 that has 4.10 gears? It's a good ratio, and the AMC 20 is a brute. In many ways it's a better axle than a Dana 44 -- but it has worse ground clearance.
HOrnbrod Posted January 31, 2011 Posted January 31, 2011 I think the OP's question was "Locker or no locker?" in his existing 4.10 geared AMC20? Not replacing it. :D
86ComancheXNate Posted January 31, 2011 Author Posted January 31, 2011 is it hard to find a locker for an AMC 20?
Eagle Posted January 31, 2011 Posted January 31, 2011 is it hard to find a locker for an AMC 20? Nope. Not hard at all.
Eagle Posted January 31, 2011 Posted January 31, 2011 I think the OP's question was "Locker or no locker?" in his existing 4.10 geared AMC20? Not replacing it. :D That was the original question. Dirt eater brought up replacing the entire axle -- which IMHO would not be a good move.
Pete M Posted January 31, 2011 Posted January 31, 2011 do you have solid extraction points front and rear?
86ComancheXNate Posted January 31, 2011 Author Posted January 31, 2011 Another question: if I do go though and do this should I get a locking diff or a limited slip diff?
Comanche_Fanatic Posted January 31, 2011 Posted January 31, 2011 no to lockers, save it for something better :cheers: ps. if ur swapping axles can i have the AMC20? :D
86ComancheXNate Posted January 31, 2011 Author Posted January 31, 2011 lol. I think I'm keeping the AMC 20.
Pete M Posted January 31, 2011 Posted January 31, 2011 installing a limited slip could cost 800 or more and needs to be done by a pro. installing a "lunchbox" locker should cost under 300 and you can do it yourself. Do you have a means of safely extracting your truck from the mud that doesn't rip parts of your truck off in the process? Don't do a mod that'll get you even deeper into trouble until you have a safe means to get yourself back out of trouble. :thumbsup: for example, hooks and brackets up front, hitch in the back.
Motion Offroad Posted January 31, 2011 Posted January 31, 2011 is it hard to find a locker for an AMC 20? Nope and not to expensive for a "lunchbox" style. Lock-Rite - $300 Aussie - $300 Yukon Spartan - $280
86ComancheXNate Posted January 31, 2011 Author Posted January 31, 2011 ok thanks. I'm going to try and see if I can get someone in my jeep club to make me up some offroad bumpers for the front and rear. then I'll think about getting an aussie locker.
Pete M Posted January 31, 2011 Posted January 31, 2011 I'm assuming they would already know, but fyi any front bumper that is to be used for extraction MUST have long support runners that go back along the frame and use extra bolts. Stock bumpers only bolt to the very front of the sheetmetal and were only designed for absorbing a crash.
86ComancheXNate Posted January 31, 2011 Author Posted January 31, 2011 yeah. I'll make sure to do that. I just recently joined the Ocala Jeep Club here in Ocala, FL. I'm pretty sure its one of the largest clubs in the area. We went on a monthly ride yesterday and we had about 40+ jeeps out there.
