My 5.7 laredo X took 1.25 quarts in the rear and 1.1 quarts for the front they both have a fill and drain plug. Changing the fluids and refilling was very easy. I recommend that you purchase the gear lube from the dealer even though it will be more expensive.

Thanks.. The gear lube is the diff fluid that you use? because I was planning on getting that from the dealer anyway and what size socket is the fill plug? Drain plug? Appreciate the response.. I have a 05 BMW myself that I do all my own work on but I'm just learning on jeeps

I believe I used three quarts for the front and rear combined. You just basically pump it in with a hand pump until it begins to seep back out.

Make sure you use the correct lube. It's not just straight up gear lube. Especially if you have one of the more advanced 4wd systems.

What drive system do you have? I know there is no alternative for QD II. Browse Amazon, sometimes you can find it on sale.

This isn't something you want to cheap out on. These 4wd systems are very advanced. Even of you found a cheaper fluid that would theoretically work, it would probably be noisy in 4wd operation.

The base awd system in a laredo

Lots of times there's perfectly acceptable mon mopar fluid. Like the manual transmission fluid in my tj.

It's not about cheaping out. I'm pretty sure there's no clutch packs or anything in the diffs for the base 4x4 system.

Assuming you HAVE to use mopar fluid is one thing. I didn't know if anyone had cross referenced the part numbers.

If anything the wrong fluid would take the bearings out, if you had qd2 and used the wrong fluid it would result in more than noisy operation.

Chrysler uses different bearings than the rest of the world?

(Rhetorical question)

So nobody knows if there's a cross over gear oil?

No, I mean if you use the wrong viscosity.

A quick forum search for "diff fluid" indicates a variety of 75w-85 oils will work, Amsoil, RedLine, Mobil... The owners manual spells out the minimum requirements, and there are several that satisfy. I don't recall seeing a single page cross reference... I think because just about any modern 75w-85 diff oil will work. Pick your favorite brand. Those that have ELSDs should use the mopar fluid, however.

This page has some detail on capacities and schedules
