Exclamation Jeep TJ 4x4 driveshaft question!

Hey Guys, So i receently purchased a nice lifted 2.4l Tj and i love it. One issue tho, The previous owner told me they took out the 4x4 front drive shaft for "fuel reasons". I knew it was bullshit because the drivers side floorboard was beat to hell (telling me that he lost a 4x4 shaft and it beat the floor up)
But anyway he was desperate to sell it to get a minivan (dumb...) so i stole it at the price and drove it home.

I want to restore the 4x4 to use it obviously but i am worried that the 3 or 4 inch skyjacker lift, or the 30 inch rough tires may change something in the 4x4 that made it pop out. Is there a drive shaft i need to get other than stock? or make a stock longer by welding in a inch? Any comments are welcome!

I haven't heard of anyone having trouble with the stock driveshaft and its length. I've got a 3.5" RE lift with 33" duratracs. It's never given me a problem. I asked me trusted local Jeep mechanic and he said there's no real reason to swap it out unless your going to do hardcore stuff or new Tcase.

I would check the yoke straps first, PO probably had it in 4WD when he shouldn't have bound up the system and one of the straps probably failed, or possibly a u-joint. I would also check the pinion output on the front axle make sure its not wobbly indicating damage.

Stock shaft will work fine... they are plenty long enough... I would check things out BEFORE I installed one....

Say he swapped in a different axle and the gears don't match front to back.... BOOM!!!! Check it good first...

the the 2.4l... you should have 4.11's for gears.... FRONT AND BACK... if they don't match... DO NOT install your front shaft until your gears match... I mean you could.. but I wouldn't... too tempted to try and engage 4x4... then you cost yourself mor money...

Alright thanks man, i checked the u joint from the 4x4 shaft a bit ago. im not sure what you can tell from moving it and making sure the front axels still turn. Didn't seam to be wobbly or anything. Im with you in that he might have just had a bad U joint. Im just worried if i got a new shaft, installed it and tried it that it would blow up again and beat the shit out of my newly rhino lined floor.
