    Bigorange30...

    Warped brake rotors have been a chronic problem on DC vehicles ever since they started putting them on vehicles in the 60's, and on every JGC since they came out in 93.

    Someone out here once wrote a very technical post on why this is happening. I'm not a metallurgist like this guy appeared to be, but in a nutshell, here's why DC hasn't and won't do anything about the problem...

    The name of the game today in the corporate world is "cost reduction" and to "maximize profit" and they lean quite heavily on their part suppliers to lower their production costs. The end result is cheaper material, less material used in the part, fewer machining steps, etc.

    Take all the complaints on JGC axle whine for instance. DC leaned on Dana Corp to cost reduce the axles they supply. There were several good articles on this awhile back. Dana changed from a traditional cast iron differential housing to one made from aluminum. They also eliminated several machining processes in production... all to reduce DC's cost. The end result is a noisy axle. Dana's reputation and stock price has taken a major hit for this in the last couple of years.

    Brake rotors are made so cheap and thin today that you're barely able to machine turn the rotors once to try and eliminate a warpage problem. Remember how many times you could resurface a rotor in the 70's if this problem appeared? You could easily expect a 50-60K mile life from a set of brake rotors back then. At least you could on a GM vehicle that is.

    The other reason DC won't address the problem is that they tell the dealers not to replace warped rotors if over 12K miles because they're a normal wear item and not covered beyond the basic 12K warranty. That's the loophole they use to weasle out of the problem. That's corporate policy and you can rest assured that this is the same approach used by the other vehicle manufacturers. DC isn't the only one with brake rotor problems.

    At best, they'll offer to turn the rotors because that's cheaper than replacing them. They know that it's a temporary fix but are hoping that it will last beyond the 12K warranty limit. After that, it's your problem and you're on your own. A voluntary recall and replacement would obviously be very costly. That certainly doesn't fit in well with today's corporate policy of maximizing shareholder/corporate profit margins.

    So what are you gaining if you can get the dealer to replace the rotors? Nothing. The Mopar replacement rotors are every bit as poor as the OEM rotors (same supply, right?). All you're doing is starting the brake rotor problem all over from the beginning. You'll be right back to square-one after only a few K miles of driving. If you have to replace rotors, go with any decent aftermarket rotor. It'll cost you a fraction of what the dealer will charge and I'd be willing to bet (from my own experience) that you'll never have a rotor problem again.

    As for recalls on the rotors... the only one I'm aware of was one issued for 93-97(?) vehicles sold in the "rust belt" states that use a lot of road salt in the winter. They claimed that the rotors could excessively corrode and the rotor could end up separating from the hub. DC had to replace those rotors. If there are any TSB's, they probably say nothing more than the rotor needs to be resurfaced.

    paramedic99, here is a page with some detailed info and photos for the JGC audio system:

  • Thanks alot for all this great information. I will try the factory speakers first as you suggest - maybe they with a new deck will sound better. Thanks again I will keep you posted.
  • THanks for the info. The pictures are great.

    A relative of mine's co-worker has a JGC (95 or so) with 150,000 miles on it for sale. I have always thought that the Grand Cherokee looked nice, but have heard of all of the gaud-awful problems. He is selling it for $3500. It was used as a salesman's car for a local air conditioning company, and is in great condition. I don't know much more, but it sounds like a great deal. I would like a JGC or something similar to be the car I take to college. Should I look at it?

    I have a 2000 JGC Limited with the Quadra Drive. Patriot Blue, grey leather, towing, everything... just want a DVD in it now. :)

    My problems are such:
    leaks from the differential (front) and transfer case
    dead battery

    Other than that, it is has been a great vehicle. The tranny is quiet on our car and we live in the mountains. If somebody is replacing their brakes every 4000 miles, I would suggest they start driving with their foot off the brake pedal. :)

    We use the tranny for slowing down on the hills, letting the engine compression do it's magic. After 59,000, I am having to finally start looking at replacing the pads. There is no rotor issue at all on my car.

    The leaks piss me off, but we knew of transmission issues with Jeeps from the get-go. We bought the 7/100 warranty too. Best thing we did.

    paul,

    You might instead say the leaks upset you, annoy you, make you angry, enfuriate you or drive you crazy. :-)

    tidester HOST-

    WHY? "Piss me off" is more with today's vernacular and to the point! ;-)) Don't tell me this is going to be banned too?

    Nah - it won't be banned and I'm not making an issue of it. I was just offering alternative forms of expression which I think are more becoming of GCers! :-)

    Okay, to rephrase my emotional condition... :)

    The issue of fluid containment in my 4 wheeled propulsion mechanism effected my bodily condition to react in a similar fashion. :)

    I will add though, that since my last service, no new leaks have shown up. I believe that the last time around, I made such an issue of it, they examined and I believe replaced all the seals on my transmission to keep it from happening again. Kudos to them for taking a proactive approach and keeping me out of the shop for that.

    Now... my battery died. :) Replaced it with an Interstate and everything is great again. I've never had good results with batteries in American (GM and Jeep) vehicles. I consider it a wear and tear item.

    A rain/windstorm passed through yesterday while my wife was out driving her 2000 JGC. She heard a sharp crack and saw that the passenger side mirror had been busted. If the electronics are ok, can the mirror only be replaced, or does the whole assembly need replacing?
  • milousmilous Posts: 39
    Yes, you can now get just the glass replaced:

    OUTSIDE REARVIEW MIRROR GLASS REPLACEMENT

    Model year(s): 1999-2002

    I am looking around and researching at used JGC's (mostly pre-redesign ones), and was noticing the dreadful reliability problems on certain models. From what I have seen, 1997-98 were its better years as far as reliability goes. Can somebody help me out?

    I am in the process of purchasing a 2001 JGC. Thought I would check to see if this is a good idea. This one has a lot of options: White, 31k, V8, Factory 10 disc CD and cassette, leather, power sunroof, heated seats, cruise, tint, etc.

    The asking price was 22K but the dealer will go for 20K - sound reasonable?

    I appreciate any feedback - I am new to SUV's and I don't want to regret my decision.

    Thanks in advance.

    A couple of months after I got my 99 JCL LTD, backing out of the garage the passenger mirror caught the side of garage. Ouch. Busted the mirror to pieces but the exterior was untouched. $135 later dealer replaced just the glass. Since then I've learned to watch where I back up. :)

    I think that dealer bent you over a long, long way...
