Hey, here is some info that may help you out. I believe you said your tires are 235/75-15's, which are a metric size and are probably the stock size for your truck. These are somewhere around 28.9" tall, when they come off the tire line. After they're mounted on rims, aired up, and 4,000+ lbs of Grand Cherokee is dropped on them, they're actually somewhere between 27.5" and 28" tall. For future reference, to convert a metric tire size (235/75-15) to a standard Light Truck tire size (31x10.50R15, for example), use this formula:
Width x Aspect Ratio = Section Height;
Section Height x 2 = Combined Section Height;
Combined Section Height + Wheel Diameter = Tire Diameter
;
(Example: 235/75-15)
235mm x .75 = 176.25mm (a ratio is a percent; 75%or.75);
176.25mm x 2 = 352.5mm (section above and below rim);
[Then you need to convert the mm to inches by dividing by 25.4, which makes 352.5mm = 13.9"]
13.9" + 15" = 28.9" tire height.
(I actually had to relearn that formula as I was typing it!)
Now that you know your current tire height in inches, we can forget about that for a while. I noticed that someone else replied to you about your tires and whether or not they rub. If they do, something isn't right! That "grind" you hear has got to be either some of your inner fenderwell is lose or something not related to your tires. As far as being easier to flip, the higher your center of gravity, the higher your chance of rolling. Most rollovers can be prevented by the driver. Once lifted, you'll notice that your Grand's body roll will have increased during turns and in curves. All you have to do is stay off the "go pedal". Lots of people seem to drive their SUV's like they're sports cars. That's dangerous enough stock. Add a lift and you've more than doubled your chances of rolling in a turning or lost control situation that could be just "scary" at stock height. Now I am definitely not trying to scare you away from lifting your truck! You'll just have to think about how careful you are now, and then be triple careful. You'll be a good bit more stable with a 2" to 2.5" lift compared to a 4" lift. Now I know your probably thinking "this guy is a sissy", but from the time I bought my 2000 Grand in Aug.'05, I could not wait to get it lifted. I finally convinced my wife to let me lift it as a Christmas gift to myself, and on Christmas Eve '05, in my garage, it took me about 45 minutes to add 2" in the rear and 2.5" in the front. Now it doesn't look like the front fenders are sitting on the front tires. And I had tires two sizes up from stock on it, with no rubbing, before I lifted it! This posting has become huge, so I'll start another in just a little bit! - dixiecrawler

Jeep leaking fluid. by 2000jeepgc
Jan 29, 2006 (2:52 pm)

I have a 00 JGC and it is leaking what appears to be transmission fluid, but all of the levels are fine. About a month ago I wasn't able shift out of park unless I let it warm up for a minute or two. Just yesterday I was driving and the car all of the sudden revved really high and wouldn't shift gears until I let off the gas. Is this a common issue? I plan on taking it in--I just want to know what to expect when I get there. Thanks.

01 Grand Cherokee Front axle whine by venturmax

My Grand Cherokee has about 95k miles and in the last few months has had an intermitant high piched squel or whine in the front axle. It starts at 10 mph and goes on up to highway speeds. The whine isn't affected by applying brakes, slowing or speeding up. It only goes away under 5 or 6 mph. It happens in hot or cold weather. Recently it has been happening all the tme. Any ideas?

1995 blower motor by robert55

I have a 1995 the blower motor will not turn off after I run on high speed.The blower motor woks fine on all three speeds. The motor runs at a slow speed with the key off. I was wondering if this could be the resistor.

Check the front brake pads to see if they are worn down. There is a low brake pad indicator, which is a piece of flat iron on the brake pads which touches the rotors, that indicates when your in need of new brakes. This is probably what the squeal/whine is all about. On the other hand, if that is not your problem, and you have a 2-wheel drive, then have your front outer axle bearings checked. If indeed they are bad, then you should get a shimmy/vibration when you turn the vehicle left/right.
 
If your brake pads are bad, and you choose to take them to a brake shop, and you have a 2- wheel drive, have them inspect and repack the front outer axle bearings.(most brake shops will do this for a small extra fee)
 
I hope this helps you, and good luck m8.

Yes it is the resistor. When a resistor goes out, the blower motor will only run on high, indicating that the resistor is indeed the culprit. However, there is a relay for the blower/heater motor that can also give you the same indicators. I'll will have to say that it is the resistor, as you describe the symptoms to a tee.
 
I hope this helps you, and good luck m8.
