Here are two descriptions of the rear axle disconnect:Does Jeep Renegade have always on AWD or is it part time 4wd?
The “Active Drive” is primarily a front wheel drive vehicle with a disconnecting rear axle and power take off unit which will give it about the same fuel efficiency as a 4×2 model.
FULL-ON FREEDOM. Two available 4x4 systems are instilled
with legendary Jeep® brand DNA. Choose the fully automatic
Jeep Active Drive,TM or get extra tough with Trail Rated® Jeep
Active Drive Low.TM Both systems feature a class-exclusive2
rear axle disconnect that helps to improve fuel efficiency
when 4x4 capability isn’t needed. Selec-Terrain,® a standard
traction management system on 4x4 models, helps achieve
best-in-class1 Trail Rated capability.
Constructed more like the Subaru, behaves more like the liberty. It's its own thing and really significantly different than both if the marketing material is to be believed.
I see the problem. You are mistaking what a transfer case does. You are used to a traditional part-time 4wd transfer case.I haven't studied it in detail, but the Patriot/Compass don't have a transfer case. The low range on the trail rated models is achieved through transmission trickery.
All of the Renegade models will feature all-wheel drive and will utilize the unique Chrysler magnetic disconnection system to allow the vehicle to become front-wheel driven to improve fuel economy. This switch is done automatically, without user input, and the Renegade will go back to four-wheel drive as needed.
Just stumbled upon this article, granted it is three months old but what is interesting is I've never seen mention of "the unique Chrysler magnetic disconnection system" Has anyone heard of it or know more about it?
Dude, seriously. There IS a transfer case. It is indeed separate unless you count bolts securing things as not separate, but then your transfer case of the last 75 years schtick needs redefining too.Y There is not a separate transfer case like we've seen for the last 75 years on 4x4s. This brings some advantages but many disadvantages also.
WXman,Dude, seriously. There IS a transfer case.
The "Magnetic System" system you refer to has been in use since the Patriot/Compass inception. The Renegade is the same thing it's just been enhanced and expanded to use more interface with the stability and traction control. My Patriots held up quite well thanks.Yes, as I was saying, the Liberty used a real transfer case. Small Jeeps since then do not. They simply are front wheel drive cars that can connect or disconnect the rear axle when needed for four wheel drive. The low range is done with trickery inside the transmission. There is not a separate transfer case like we've seen for the last 75 years on 4x4s. This brings some advantages but many disadvantages also.
With the Cherokee/Renegade Jeep is trying all new things in the segment such as the dog gears they used in the Cherokee, which were very problematic at first and this magnetic system on the Renegade which will likely have bugs at first. Only time will tell if these new tricky systems will last 200,000 miles. I personally don't expect them to survive as long as traditional systems like the Wrangler still uses.
I agree.This forum is finally getting good.
The Renegade's AWD system is pretty heavily integrated, but not with the transmission. At this time, the cost for the transfer case is ~ $1200 and the cost for the rear drive unit is ~$1200. (that's if I go order it form someone with decent prices, the invoice on my warranty replacement of the rear drive unit IIRC was $1540). The transfer case is listed as a separate part# from the transmission, although you would likely need to remove all sorts of stuff to get it out of the vehicle, and those prices do not include labor.I do not know much about the mechanical parts of cars. I hope someone on this forum would know how to answer my question. I had a 2008 mercedes c300 4 matic. This was the first year this model was produced. At approximately 79,000 miles mercedes told me my transfer case was leaking and needed to be resealed. I paid $1200 to reseal it and a year later they told me the bearings on the transfer case were worn out and metal shavings were going into the oil. The transfer case and the transmission are sold as one unit. They told me I needed a whole new transmission for $7000. Is the Renegade made with the same type of transfer case that you would need a whole new transmission?
