tell me a bit about the patriot 4wd system

zippome · 08-25-2009, 09:14 PM

so i have a wj but i have a few questions about the new patriots. my dad is looking for a car to replace his forrester xt and of course i thought jeep. i cant really find too much info about the 4wd system in these things. is it 4 wheel all time or can you switch from 2 to 4. is it electronic can i dictate when it does what. a 5spd, 4x4 patriot would be ideal.

thanks
mark

In short, the 4x4 MKs are FWD until slip is found. Then the rears will kick in. You can use the 4x4 lock switch, which makes it 50/50 all the time. Otherwise, I believe it's 60/40 if memory serves me correctly.

Look up FD-I (one) and FD-II (2) and you'll find more info.

Below is a few "Similar Threads" to go through as well.

i read up a bit on them. so is there a way to lock it in 4wd with FD-I? because you cant get it 5spd with FD-II, correct?

This could be worth a read.

Correct there is a switch/lever to lock the 4wd in for low traction conditions. And you cannot get FDII in 5spd manual.

Old thread but have a question on a Patriot with 5 speed and FDI

What transaxle do they use for the 5 speed and since the system can be locked, at what speed can you drive it in the locked mode. Could you drive it on the highway when it is snowing in the locked mode doing say 45-55 mph??

Jeep marketting needs a kick in the *** to explain.

I assume on snow/wet highway one can lock it so the tourque is split 50/50?

Or can you only lock it and drive slow?? If so what is the max speed?

I am not a fan of the real time AWD systems, friend has a body shop up here in maine and fixes way too many smashed up lezabrus Forrestor and Outback junk and now CRV;s with their crap systems. as he says, from the wheels that grip, to the wheels that slip then into the ditch, tree or some other poor vitim next to them LOL

I have the 5 speed manual and I heard that it is based on a transaxle used for a Neon. I have used 4X4 Lock which is 50/50 at highway speeds in deep snow, no drama at all even though the video says low speed. Full time 4X4 is Not 60/40 but is 100% FWD until it needs more traction or performance.

The 5 speed is a T-355.

You can turn the lock on/off at any speed. The lock is a 50/50 to start out and up to about 25 or so for snow/poor traction conditions and then reverts to an "on demand" so you can leave it there even on dry pavement. Since it's connected electronically you don't have the same differential wrap up like in a gear driven 4x4. I've run mine at 60-65 mph before.
