sooo.. i noticed somthn weird..

well the other day when i was muddn with a buddy from school, and when i had er in 4, i noticed a more than usual bind when at full turn. ya know the weird turning when in 4x4. you 2wd guys are outa yer element haha. anyways, well i have an lsd in my open 8.8 now, and when i was turning in the parking lot at full turn, there was some major slow down and binding feeling. and then i heard the chatter of my outside tire in the turn. so i pop my head out. and my rear end..only in 4x4.. acts as if its welded. its choppy just like a locked or welded diff. i ight be missing somthn here but i am totaly clueless as to why it would change from 4x4 to 2wd and how it makes it almost locked in the rear.

i might be asking for a .."your a retard" but yea

so yea, wtf mate?

you are a retard.... no **** theres gonna be a binding feeling when at full lock in 4wd in a parking lot! whew... sorry.

now, as far as the limited slip thing may go, it might be because you are pulling the front of the truck with the 4wd that there isnt the same forces on the back end.... i really dont know about that...

are you sure it was from the back or could the chirping be from the front?

yea i know,

i noticed it on the trail first, then at the end of the day, i was in the lot next to the trial and i was just trying it again to see what was up.

but yea it seems as if the lsd makes it work against eachother a bit more. but yea just thought id get that out there see what people thought. thanks for the input

When in 4wd, your front drive shaft is spinning at the same speed as your rear drive shaft. This means that your front and rear gears/axles are trying to turning at the same speed. When you turn, your front axle is going in a larger arc than your rear axle. Same axle rotation on a longer path means that your rear axle is trying to push your front axle forward faster than the wheels are turning. Because the front of your truck is heavier than the back, there is more friction between the those tires and the ground. The back tires slip first, hence the chirping. A LS or Locker will only make it worse, or maybe more noticable, because instead of letting the uneven drive shaft speed be split between the two tires, it's the same, and traction is upped.

Like Alon said though, it is VERY BAD to do this, even once, on dry pavement. 4wd isn't for high traction areas. It's almost as bad as having one axle in forward, and the other in reverse, or at least it's putting the same amount of stress on the gears. Turning actually makes it worse because in addition to the stress on the gears/axles, your also putting A LOT of stress on your A arms.

Hope that helps a bit...

Don

It's not as bad as you guys seem to think. I've driven in 4wd a lot on dry pavement. When i drove up to canada i needed it for hte ice patches on the road. I jus made sure to get fully on them to let the tires slip.

No offense, but why is it "not as bas as you guys seem to think" just because you've done it "a lot"? I can drive my car in reverse for miles down back roads, and I have, but it doesn't mean it's a good idea or that it doesn't put a lot of stress on the drivetrain of the car...

If you have to do because you can't keep traction on icey spots in 2wd, then you have to do it, but it's still not good for your truck on the dry patches in between. Even if your not turning, there is still a lot of things to take into consideration that can result in drivetrain bind simular to what I described above. In the end, will it make your truck explode? No, of course not, but when/if you have problems later with your CVs, Axles, Trans, Ball Joints, maybe you'll understand some of the contributing factors.

in 4wd it does "lunge" almost like a cam going up and down. I wont say that all 4wds do that but my sfa cherokee does it as well as my ranger.

I only say it because from experience most people aren't having probelms. Lots of people drive their vehicles on dry pavement in 4wd at points, whether it is accidental or because they don't know better. Many people don't understand that it is bad for the system. But it's not really something to worry about. Anyways i doubt i'm going to be flipping hte 4wd swtich on and off between icey patches. Find me a thread on this website about 4wd going out because of binding. I sometimes hear of a cv joint breaking from large tires.
