I know that the rav4 is not a real 4x4, but we all got to start somewhere, right?
disclaimer: I know that the rav4 is not a real 4x4. I have very
little knowledge of 4x4's. This is why I came here. I would like to find some patient person who will be kind enough to not flame, but dispense out some basic knowledge Dear all: My buddy just bought a Rav4. I helped him pick it out. Since I am currently unemployed, I have a lot of time and scanned through many ads and found a black on dark grey Rav4 1998 with only 99k miles. It is a manual drive (which, I think is the only way to go), and it has just had timing belt and water pump replaced. The price was unbelieveable @ 5700 dollars. The carfax report was clean and the car is clean and drives well. Both he and I have never owned a 4X4 before. We were just wondering about the finer points of driving one. The guy who showed us the car taught us a little: to demonstrate the differential locking, he had us engage the 4x4 and then turn real tight circles. We felt the diff grinding in those turns. Was this really really bad for the differential when we did that repeatedly? Now that I think about it, I am hoping that we didn't put undue stress on the differential. My buddy is going to park it at my house and I live on an air force base. I am hoping to take it out and use the 4x4 feature. I have some grass areas. I am hoping that on grass, I won't grind the differential. I just don't want to hurt the car. I am also going to try to find some ice and see the traction. I know these are not very good questions I am asking. This is because I don't really know the questions to ask. Could someone just start at the beginning and dispense out some good knowledge on how we can get the most use and best fun out of the 4x4? I know this rav4 is not an outright offroad car, but I would like to take it to some terrain or some conditions where I can really appreciate the 4x4 features. sincerely, thanx in advance. |

Many people want 4X4s for different reasons. Some want to explore the
lesser travelled trails and get out into nature. Others want to be able to get from place to place in inclimate weather without worry. Still others get hit by the offroad bug and modify their vehicles for extreme duty. Each different 4X4 vehicle appeals to as many different people. Some are stylish while others are more funtional and rugged. Prices vary along the same lines -- you pay for what you get, style, function, capability. All of the major manufacturers both national and international have produced a good crop of capable 4X4s. They all have equally created a few poorly designed and incapable vehicles as well. ( In my opinion the RAV4 is one of these) All the vehicles have been designed and manufactured for general on highway use with vehicle safety regulations paramont. In fact, avid offroad use with any of these almost always requires aftermarket modifications just to meet the average, unknowing buyers expectations. Such mods usually are bigger tires, suspension lifts, gear changes, traction devices and so forth. For my personal preferences, I wanted capability in difficult off road conditions while maintaining on highway manners and safety. My vehicle of choice was a Jeep Wrangler. My Jeep is considered highly modified by stock vehicle standards, but I can do anything I want with it and also use it as my daily driver. For the novice, there are a few simple rules when exploring the 4X4 realm: 1. Never stress your vehicle beyond its capability or it will break. In order to follow this rule you must learn about your vehicle and what it can do. Your owner's manual is the first place to go. Follow its recommendations for the conditions you want to drive in and then go try it out. If you find it lacking in capability, then research what you have to do to improve it. Remember this -- 4x4 doesn't really mean you have 4 wheel drive. When you shift into four wheel drive all you're really doing is transfering engine power and torque to both axles instead of one. Because of differential design only one wheel on each axle is driving the vehicle. Normally, the wheel with the least amont of traction gets the power. That power or torque will shift from one wheel to the other during different traction situations, but still only one wheel on each axle will have power. An example would be if you have one wheel off the ground (no traction) and one on the ground, the wheel not contacting the ground will get the engine power. Does'nt seem right but that's the way it is. 2. Never under any circumstance place your vehicle in four wheel drive on dry pavement. Four wheel drive is for situations where there is loss of traction. The four wheel drive system on most 4X4s needs a certain amount of slippage. Without slippage the driveline will be stressed and could result in damage and expensive repair bills. 3. Never go four wheeling alone. Always take a friend with his own 4X4 and a tow strap along for the trip. Things can happen like getting stuck miles from nowhere with no help. I can't tell you how many times I've happened along on this situation. 4. 4X4s are maintenance intensive. I know you've heard this before. What it really means is that if you intend to take your vehicle off road then preventive maintenance is the best insurance. Check all your fluids to make sure they are at the proper levels. 4X4 use makes your vehicle work harder than on the highway. As a result, fluid changes like the oil, transfer case and differentials will be required at frequent interval as well as lube. Not only will this keep your vehicle in prime shape to handle the trails it will ensure a long life to your driveline and suspension components. Also, off road use will eventually result in something breaking. 5. Obstacles and other unforseen trail anomalies. Never try to bonzai an obstacle to get over it. Not only is it unsafe, but you will put unneccessary and potentially damaging stress on your vehicle. Slow and deliberate is the rule. If you can't negotiate the obstacle in this way then you just discovered your vehicle's limitation. Sure, you may be able to get past the problem with a little extra throttle, but be prepared for breakage. Now keep in mind that in these few short words, I have come no where near describing all of the nuances with 4X4 vehicles or their capabilities. Nor have I delved to deeply into various off road situations and conditions. Suffice it to say, I've given you the absolute basics. Here's my opinion on your vehicle -- The RAV4 is a relatively inexpensive, light duty 4X4 vehicle with limited capabilty. Is is well suited for on road limited traction situation in rain or light snow. Off road should be limited to unimproved dirt roads and minimal obstacles. It is economical to operate and possesses sufficient quality comensurate its Asian manufacturer. It would not be my first choice for a 4X4. Hope you get something out of this.

Find a plowed icy road with snow piled on the side, and drive both side wheels into the snow (as if parking on the curb) while other side stays on (icy) road. Congratulations, you're stuck! Wheels on (icy) road will have less traction and will be spinning, while wheels in snow won't even turn. Peter |

This will load up the wheel on ice that is spinning and transfer some torque to the wheel in the snow that has more traction so isn't turning. This is an old trick and it works very well with some practice. I have been sitting on ice a few times with one front and one rear wheel just a spinning away and folks are going for the straps to give me a tug when I nail the brake pedal pretty hard while giving it gas. Bingo, 2 rear rooster tails and sometimes all 4 catch. It works easiest on the rear drum brakes. Mike 86/00 CJ7 Laredo, 33x9.5 BFG Muds, 'glass nose to tail in '00 88 Cherokee 235 BFG AT's |

I have I do know about that trick, but have never been able to actually do it - feels like I'm breaking something by flooring brake & gas at the same time. It should be putting some undue strain on transmission, doesn't it? Peter |
