Hi

I am doing a little research on the Patriot. May want to upgrade one of my winter cars to something a tad bit newer.

I am a Mopar guy myself but am not the familiar with them. If I bought one would probably get a Laitude or sport 2.4 5spd with the Freedom drive 1. From what I can glean from the useless Jeep description on their web page(Sergio should fire the clown who wrote that up) the FDI if it isnt locked acts like an on demand system, ie when the front looses traction it will transmit tourque to the rear axle.


Anyhow I assume there is no transfer case and there must be electronic clutch pak in the rear diff to engage it?

I see they have a T-handle to lock it if one would like and this would split the tourque front to rear. Not sure of the ratio. But this appeals to me since the on demand systems are inferior, I would prefer having both axles getting tourque in snowy conditions.

My question is can you use this feature at highway speeds and can you also use it on dry pavement?? Ie lock it with the t-handle doing 60sh in wet/dry or snowy/dry type conditions?

I have a 4.7 jeep with Slec trac and in full time 4wd it splits tourque 50/50, no wheel slippage crap and one can lock it if one desires. I like the full 4wd because on snowy road, the odds of loosing traction on both axles going 40-50 is nil and the jeep tracks nice and straight. Ditto my Durango which has the same t-case less the 2wd option.

My pal owns a body shop and discussing with him over the years, the on demand AWD(ie fwd until slippage occurs) systems are the #1 smashed up cars which come into his shop. Usually the story is, 2-3"s of snow on road, doing 40 sh, car gets squirrelly fish tail, from the wheels that slip to the wheels that grip and into the ditch and to his shop or junk yard they go! Sees loads of subarus and CRV's etc He had an older CRV in his shop, told me if you want to kill your wife, buy her one of these. It was in accident on a side road and the women driving it was seriously injured with both legs broken. He talked to the police when they towed it in. they said they had witnesses it wasnt to violent a crash, just a fender bender deal but the whole front was stuffed in and the intrusion into the dash and front seats was bad.


My other questions are general.

I know the new world 2.4 uses chain to drive the cams. How do they hold up long term, ie 150K plus miles??

How is the suspension on these holding up, My PT's have issues with the LCA bushings but I just by new Moogs and slap em in.

How is the highway gas mileage? Do they get the 28 mpg for 4x4 5spd??

Lastly how difficult to change the fluid in the 5spd manual transmission and the rear differential? What do they take for fluids? I assume the trans probably ATF+4 but what about the rear diff?
 
The "T-Handle" is a lever for a switch, with no tactile feeling of engagement. Lift it up and a little 4WD light above the odometer illuminates. My wife was conducting a test drive and I found/lifted the lever. Without a "feel" of engagement, I did not know I activated 4WD lock. Later in the test drive, I noticed the indicator, lifted the lever (it really could be a button on the dash) and disengaged the system. My wife never noticed anything.

You're correct with all of your assumptions. FDI Patriot is FWD unless slippage occurs, then it becomes AWD. If you pull on T-handle, it splits torque 50/50. There is no transfer case as you said. You can engage 4wd lock at any speed. There is no timing belt. There is a chain. I don't think anybody here reached 150k miles. Not even sure if the chain needs to be serviced or replaced at all. OEM front suspension components are weak and poor quality. A lot of folks have replaced them with Moog parts. It seems they break at around 40k-60k miles. At some instances even earlier. Remember I'm talking about 07-09 models. As far as mpg on 5 speed goes, I think you'll get close to 28 mpg depending on your driving style. I can't speak for myself as I have CVT.
 
There is an electronic unit behind the transmission which controls the torque going through the rear driveshaft to the rear differential. With careful, non boisterous driving, I have gotten the gas mileage in my signature.

For fluids, my 2008 uses

Manual Transaxle Fluid, Mopar ATF+4 MS9602
Rear Drive Assembly (RDA), Mopar Gear & Axle Lubricant SAE 80W-90 API GL 5 or equivalent nonsynthetic product.
Power Transfer Unit (PTU), Mopar Gear & Axle Lubricant SAE 80W-90 API GL 5 or equivalent nonsynthetic product.
 
If you pull on T-handle, it splits torque 50/50.
Just going to toss in a clarifying statement here. It asks permission to split the torque 50/50. In some instances this request will be denied without you knowing it. An example I noticed on my test drive was under tight turns on high traction surfaces it unlocks the 50/50 split to prevent drivetrain binding. I believe this should fine almost all of the time and it's a setup I prefer to a true 4x4 on a vehicle my wife (who is not a car person) would be driving.

Thanks for the feedback.

The transaxle and take off for the drive shaft to the rear must pretty complex.
