I have a 2000 Jeep Grand Cherokee w/ 4.7l and all time 4 wheel drive.?

Question

Can anyone tell me what will happen if I have a front cv joint failure at speed?

Answer 1

The full time 4WD sends power to 48% front 52% rear so if you loose a front CV shaft and have the all time 4WDsystem you will NOT be stuck on the side of the road, you will be in 3WD with the rear tires and the good CV shaft getting you home.

There are warning signs to a CV shaft going bad...The most common is a popping sound that can be heard when making turns. I would not recommend long distance driving if it is on the way out.

Answer 2

First of all your jeep has a semi-solid front axle, meaning that there are no U-joints, the outboard connection to the wheels is a CV joint. The connection at the differential itself is a splined axle. So there's only 1 CV joint on each side that can fail. The rear axle is still a solid axle so you don't have to worry about that one, unless internal parts break (not very often unless abused).

If the CV half-shaft fails it will cause damage to the surrounding area of the vehicle mainly any brake lines in the way could be damaged. Loss of control of the vehicle could result in a roll-over totalling the jeep. Since your jeep is full time 4wd it makes it that much worse because after the shaft breaks which is continuously spinning it will cause further damage to other drive-train components due to the sudden torque change, which completely thows the 4WD system into a confused state, trying to shift torque and power to other wheels and if you continue driving it will overheat the differential.

Its best to have potential problems fixed before they fail, its always easier and less money.

Answer 3

Well first of all you dont have front CV Joint, you have what is called a Live Axle, Now you drove a toyota u would.

I thinking you talking about U joint? if U joint fails drive shaft will beat the crap out under side of your jeep and prob make your transfercase explode.

Answer 4

You will know if you have a CV joint failing.....

It is not a part that 'suddenly' goes bad at road speeds. It will make noise for a while before complete failure. But when it does completely fail, the vehicle will be disabled.

Usually, they will either lock-up and not bend properly at the joint any more. or they will seperate and fall apart at the joint.

Answer 5

It probably depends on the year. Older means you may need to lock out the front hubs. There will be a "knob" in the center of each front wheel. Turn it from the "free" position to "locked." Then inside the vehicle, there is a gear shift lever that would indicate 2 High, 4 High, and 4 Low. Probably select 2 High unless you are going in REALLY rough terrain. My Nissan has instructions on the visor as to what gear shift position is what mode of 4 wheel drive. You may also watch for a dash light indicator as you move the 4WD shifter. Our Blazer is much simpler, and newer, it just has two buttons on the dash. One for 2WD and one for 4WD. There are small lights in each button so you know which is activated. Hope these thoughts help.

Answer 6

you will potentially lose the front portion of your all wheel drive thus making it a real wheel drive. BUT do not drive a vehicle in this condition because that particular scenario is not suitable for your vehicle because it will cause transmission failure if not immediately then soon after your cv joint fails. do not drive a car which needs a cv joint replaced or repaired.

Answer 7

In general any time you have CV failure you will be disabled on the side of the road. Period.

Good Luck

P.S. Why worry about this kind of stuff. They are rare.

Answer 8

you will buy a toyota or honda because you realize chrysler is junk

Answer 9

you will crash so buy a toyota
