Confedneck Posted February 17, 2008 Share Posted February 17, 2008 good story here, let me try and make in tolerable to read lol yesterday afternoon, my buddy came over, and he's a catalyst for me breaking trucks and doing stupid $#!&.... we decided to go for a ride in the MJ.... first we headed to a customer of mines shop where they were buttoning up a 1ton LJ on 38s... left there and hit a little easy canal-side trail on the way back to my place. my buddy spotted a hill off to the left so we headed towards it, it's a 4wheeler trail going up, so i figure, wtf the mj isnt too wide.... well made it up in 2wd then dropped the rf tire off the other side... put it in 4hi and back up, turn the wheels hard left and end up in the brazilian pepper bushes, not good, back down the hill, and take the line up it to the right, dead end there... no good either... back down to the trail and around the otherside of the hill.. its almost a straight up climb, but we figured wed get the front tires as far up it as possible, tried it in 2wd, but no luck,,, so put the tcase in 4hi and stalled it up just past the convertor and climbed about 3' and POP KAPOW BANG.... all batman-esque noises.... back to 2wd, back to the house... no broken ujoints, front driveshaft spinning.... last time i did that, i blew a carrier in half on my 1/2 ton chevrolet.... luckily i just didnt have the CAD fork spaced over with wasers quite enough for good engagement... fixed and ready to roll.... better? lol Link to comment Share on other sites More sharing options...
speed_racer Posted February 17, 2008 Share Posted February 17, 2008 Good thing you're not a writer. It's easier for me to follow Vonnuget (sp?) lol. Glad you fixed it tho. Thats what you get for halfassing it the first time, hahahaha Link to comment Share on other sites More sharing options...
BLHTAZ Posted February 17, 2008 Share Posted February 17, 2008 It pays to think of the simple things first. Glad it wasn't serious :cheers: Link to comment Share on other sites More sharing options...
Oizarod115 Posted February 18, 2008 Share Posted February 18, 2008 ... ever heard of 4lo? then you don't have to rev it up ;) at least she's not broke! Link to comment Share on other sites More sharing options...
Confedneck Posted February 18, 2008 Author Share Posted February 18, 2008 4 lo? thats why i bought a 4.0 lol Link to comment Share on other sites More sharing options...
Oizarod115 Posted February 19, 2008 Share Posted February 19, 2008 4 lo? thats why i bought a 4.0 lol 4.0Ls have plenty of torque to get over stuff, but gearing is your friend man... you don't want to rev more than you have to, unless you like POP KAPOW BANGs Link to comment Share on other sites More sharing options...
xjcrazy09 Posted February 19, 2008 Share Posted February 19, 2008 Also you should use your low so that you don't screw over your transmission. Link to comment Share on other sites More sharing options...
Confedneck Posted February 19, 2008 Author Share Posted February 19, 2008 hmm, its just a $1k MJ... it was bought to be beat... its gonna need a rebuild on the drivetrain soon anyways... so again i say, i bought one with a 4.0 so i wouldnt need 4lo... the time it won't break stall cuz the tires are that bound up, ill hold it to the wood til it blows... what better excuse to rebuild?

Pete M Posted February 20, 2008 Share Posted February 20, 2008 Gearing really is your friend. I've got a 4.0 and do everything in 4lo. No amount of engine torque will be better than the sweet control that low gearing gives. Even the big dogs use low range for everything but maybe sand and mud pits. It lets your engine stay in its optimum rpm (which I think is about ~2k for the 4.0) at the same time the tires are at their optimum rpm. (granted that the terrain "optimum" will change which is probably why there has been an explosion in available gearings for t-case, both stock and aftermarket) Link to comment Share on other sites More sharing options...
Confedneck Posted February 21, 2008 Author Share Posted February 21, 2008 ehh i think its really broken this time... got a nasty grinding noise and no 4wd, got lo range, neutral and hi, but no front wheel drive.... mebbe the tcase, mebbe the front axle again... tj shaft time i think Link to comment Share on other sites More sharing options...

I just don't agree with this whole "Drive it like you stole it" thing... Sorry man, but driving like that is plain dumb. Whipping the snot out of your rig because you can makes no sense. Not to mention anything about tread lightly... Whats this nonsense about 4.0 not needing 4lo???? Come on!! Give it a try, you just might surprise yourself!!! Your Jeeps got it for a reason, It would not be there if it wasn't needed. Try accomplishing an obstacle with out spinning a tire or having to back up to take a different line. That's DRIVING. Bouncing off the rev limiter as you climb a rock pile is ...well...its dumb. CW Link to comment Share on other sites More sharing options...
Confedneck Posted February 23, 2008 Author Share Posted February 23, 2008 you do know i live in florida, right? hillclimbs? not spinning a tire is not an option in the mucky goo we play in, and i havent found a revlimiter yet on my mj, does it have one?

Mud IS a different animal. It also dose require wheel spin to keep the tread as clean as possible. Your also likely best to keep it in 4HI as well, to keep wheel speed up. Just watch the RPM's as you'll be warned by floating valves just before you punch a hole thru your block when a connecting rod lets go. :eek: :oops: I was thinking rocks as this is what many prefer, mud is fun but is something you grow out of, it ruins seals and is a pain to clean. When you do get to some rocks, 4LO is your best friend!! Have fun with it!! CW Link to comment Share on other sites More sharing options...

Confedneck Posted February 24, 2008 Author Share Posted February 24, 2008 i guess if a hill is a 12' tall hardpack dirt mound, sure.... and if you can't have fun wheeling the way you want to, i suggest you quit wheeling... not so sure ill grow out of mud either... its been my primary off-road experience for the last 7 years and I'm pretty sure it'll stay that way, it's what we got here Link to comment Share on other sites More sharing options...
BLHTAZ Posted February 24, 2008 Share Posted February 24, 2008 Yes...there are a lot ofmud-loving people here in FL...BUT...I am NOT one of them. I would rather tow my Jeep 10 hours to find good rocks before driving 15 minutes to a mud hole ;) I used to do the mud thing and found that 4hi was definitely my friend in the mud holes, but 4lo is so much more fun on rocks when you can feel the vehicle work and you get to use some driving skill to make it through the obstacles. :cheers: Link to comment Share on other sites More sharing options...
Confedneck Posted February 24, 2008 Author Share Posted February 24, 2008 i had a truck with real 4lo, 6.55:1 first gear and low range, i could walk that old chevrolet anywhere, but still used 4hi... i like wheel speed and vehicle speed... but all i get to ride is mud and sugar sand Link to comment Share on other sites More sharing options...
