Rear end serious problem


Axle wrap is normal because Rangers are rear-wheel drive. The reason axle wrap happens is because when your truck accelerates, it loads one wheel before the other. What happens next is the load force--acceleration--then gets transfered into the the axle casing, due to driveshaft rotation. The axle then wraps at the springs, causing the axle to lift slightly on one side.

Then why does a ranger with a locker have axle wrap?

Then why do 4X4 pickups with leafsping front axles get axle wrap on the front axle ???







This outta be good.

Axle Wrap doesn't "Lift" the axle on one side. And it DOESN'T happen because the vehicle is rear wheel drive. It happens because, well, they're leaf springs. There has to be some kind of "give" to them. Axle wrap occurs when you have traction at the rear/front tires. When you gain traction too quickly, the differential rotates up (or down ) causing the leaf springs to twist into an "S" shape. This usually binds the u-joints in the driveshaft, making them wear out prematurely. This is when you feel that "jumping" sensation. Is that good enough for you Scooter?

You ruined my fun......:bawling:
 
thank you all for the responses. i now know exactly what axle wrap is.. lol but i installed the leaf spring and it definitely improved ride quality, and i'm not feeling a difference in using a 2wd spring? they seem to have the same spring rate but i may be wrong.. all i know is it is definitely better than before.
 
A leaf spring's a leaf spring as long as the leaves are all the same thickness and length.

Actually, the person that posted after this is wrong; axle wrap happens not because of the leaf springs, but because of the rotation of the driveshaft. The torque (rotational force) that goes into an axle, whether front or rear, will cause the side of the vehicle that has more load to press down into the surface the tire is getting traction on. Because the other side has a slight delay in also getting that traction, that side rises (not by much, and not for any significant length of time). As a result, the side that has already gained traction forces the other side (the side doesn't have traction) back down to the road surface; hence the term "wheel hop."

The springs, while they do have some give (if they didn't, the ride quality would suck), they are not the reason for axle wrap.

As for an axle with a locker, I'm assuming that while the axle is "tied together," the torque on the axle, from the driveshaft, still cause a small amount. It's the reason why one wheel on a locker will slip while the other doesn't. Same thing happens on a Dana 35; the front driveshaft torques the axle, causing it to lift on one side. Also, on a related note, usually the side that has the ring gear in the differential will be the side that receives load from the driveshaft and transmission first; this is usually why, when the road is slippery, that the ring gear-side wheel spins first. This is the reason for limited-slip differentials: The LSD works to distribute acceleration load to both wheels at the same time (in theory) to allow both wheels to gain the same amount of traction at the same time. You see this all the time in drag racing; if one wheel only were to gain traction, the car kicks to the side that spins. As a result, you lose time on take-off, and usually lose the race. This is why cars like the Subaru WRX use LSDs in both the front and rear, so that wheel slip and axle wrap are eliminated on things like take-off and exit speed (both for rallying and regular road courses).

Way to dig up a DEAD thread.

He figured out what was happining. Let it be.

Edit: Did you even READ the whole conversation begining to end?
Believe me, i know what a locker, LSD, and wheelhop is. You quoted the wrong guy.......

I think he quoted a quote and then copied and pasted into your quote to make him look smart :thefinger:

Gawd i hope so!!!! :thefinger:

But im not THAT smart. Apparently im not smart enough to figure out why leaf sprung vehicles get axle wrap.
