CRD stands for Common Rail Diesel according to Jeep's website.

FYI: The link under 'Tire Size Chart:' is broken.

What tranny does the 05 CRD come with and how is it different if at all from the gas model?

They have the Chrysler-designed electronic 545RFE 5-speed automatic - the same one found in Hemi-powered Ram trucks.

Gas models have a 5spd manual, 6spd manual (depending on year, 05+ models have the 6spd), or a 4spd auto (42RLE), depending on engine (2.4L I4 is manual only, 3.7L V6 can have either).

What is the difference between lowered and prelowered?

What lifts are available for the KJ?

What is the largest tire size that will fit without rubbing (with and without a lift)?

What changes have occurred between the 2002 and (present year model) KJs?

On my 2002 I have the rocky road OTT lift and I put 255/70/16 Revo's on it and they rub like crazy. I had to cut out some fender and smash back the pinch seam.
I just ordered the Rockfather II Kit and will have it put on next week, let's see if this helps.

05 and 06 CRD's have the 5-45RFE transmission

And that the 2005 models have a new plastic kick plate.

And possibly that the Renegade models have different hoods and front grills... (flatter hoods, bigger grills with no fog lights, as they are on the bumper (and a slightly different bumper as well))

For 06's as well.

Also the 05-06 CRD's have the 545RFE 5speed auto trans.

The 06 CRD also has the NV242 transfer case

I have only heard and read "Common Rail Diesel" that is what is says in the DC broucher

almost a year later.....lol....try the lostkjs.com site for a great bunch of liberty owners, friendly folks (yes, i'm a member), and very willing to help, advise, and lend a hand when able. i would say that nearly any question a KJ owner, or perspective KJ owner might have could be answered on that site.

It's not because the 4wd is heavier. It's because the center of gravity is lower.

Yes, it's heavier. But the added weight (transfer case, front drive, front driveshaft, etc.) is down low, which is why the center of gravity is lower.

I have seen something called TRAC-Lock - what is it and how does one find out if their KJ has it?

[WilliamH]

Trac Lok is a multiplate clutch type limited slip differential made by the Dana corporation, which is installed in various Dana built Jeep rear differentials.

An open differential (most common type in use) allows a difference in wheel speed between rear wheels (as well as front wheels on a 4wd while 4wd is in use), which is needed to allow the vehicle to corner normally.

However, an open differential can allow the wheel with the least traction to spin, while the wheel with the most traction doesn't get enough torque to propel the vehicle. The most extreme example of this is with one wheel in the air. The wheel in the air will spin, while the one on the ground will be stationary.

The clutch plates in a limited slip differential are packed loose enough to allow a difference in wheel speed when needed (although there will still be some friction). But when there is enough difference in wheel speed, the clutch plates are pressed together tighter, increasing friction, which fights the difference in wheel speed. This allows a certain amount of torque to be transferred to the wheel with traction, which propels the vehicle forward.

There are problems with a clutch type limited slip. One, the clutches can be overcome with too much torque, allowing them to slip, which limites torque transfer. Two, the clutches can overheat, which reduces their effectiveness (until they cool). Three, they will eventually wear out, which reduces their effectiveness permanantly (until they are replaced).

I'm not sure if your KJ would have a Dana Trac Lok. It has a Chrysler 8 1/4" rear differential instead of a Dana differential.

If it has a limited slip differential but doesn't have Trac Lok, it would have Chryslers' brand of limited slip differential (which would be very similar in design). I'm also not sure how to tell on a KJ if it has a limited slip or not, other than actually driving it and experimenting with it to see if it has one. This is where the Jeep experts need to speak up.

It is Common Rail Diesel...but i can see how it can be mistaken for Common Rail Direct...becuase it's a high pressure common rail direct injection fueling system

[gotazukitoo]

anyone know about KK (08libi) gear/info sites. And would Commander parts work on it? For example, bumpers etc...
