what kind of diff do I have lol

Just got an 07 laredo 4x4 and it has the full time 4x4 wondering if there is a way to make all the tires spin instead of just one or two, maybe lockers and if so how hard is it to install. Any advice is helpful

OEM utilizes open diffs (3.07s), hence the spinning. And you could certainly install locking diffs but its gonna cost ya and wont be practical except for off-road use. You can certainly hook this thing up to be a monster and Id agree if you said these things aren't super capable from the factory. Granted they're good in light mud/snow w/ the AWD and some decent tires. So I guess it all depends on your needs, goals and budget

Ya I've been off road with it last week but got stuck a couple times from the factory diff. I do have plans to make it an off road beast but just need money and knowledge about parts, mainly lockers. If you know what are some good ones out there please tell. I also am planning on putting a rocky road 2.5 lift or one from rustys plus bigger meaner tires but wanna fix the slipping first

Re: what kind of diff do I have lol

Do you have a 3.7 V6? If so, then you have 3:07s. If you have a V8 or CRD with low range, you have 3:73s. QTII uses brake traction control to function like lockers. QDII has ELSDs which provide full lock F/R (essentially lockers). If you have a 3.7 V6, I would suggest upgrading to to QDII diffs with the 3:73s which would really help you out when you put on bigger tires. You can then wire up the ELSDs so you can use them as lockers on demand. There's a guy with QTII who installed a QDII front diff and successfully wired up the ELSD on theultimatejeep.com. Good luck!

Re: what kind of diff do I have lol

Yeah what jjt250 would be your best bet, retain the OEM Jeep diffs and Id imagine the swap is pretty simple.direct being as the chassis mounts would all be the same and the electronics would likely not be a huge issue being WK -> WK. Plus you could probably find some for pretty cheap through a junkyard so you'd save over going new.

As for lockers you're gonna want an LSD not a true locker because otherwise your gonna have lot of driveability issues on the road going around bends which you dont want. Mechanical or electric (which uses brake system normally) are the most common but you could also look into having someone who does rears/welding weld your open diff to make it locker.

Sorry to thread revive.

I've got the hemi in my 2010. I want it to be a lsd or lock it up. It's rwd only

I know it's a long shot., but does anyone know of someone that welds them out in the San Antonio area? Or another route to go aside from the welding
