what? what do you mean you "tested" it?? lol, if there was a problem with your LSD you wouldn't be able to drive the car.

dude, it's not your diff or lsd.

wisconsin s2k.
the car can be driven even if the LSD is faulty.
LSD only operates when going around the corners, that's what it is there for, so that each rear wheels can rotate at different speeds.
The outer wheel has to rotate faster, which I assume you already know of.
When going straight the whole LSD housing, or i would say the differential carrier rotate together with the axle shafts.

Inside the torsen LSD, there are 2 side gears, 8 planetary gears and 3 side washers. Any of these gears inside the LSD housing could be damaged or those side washers or side gear could be bonded together, which the driver could feel the binding feeling when cornering.

Oh, well, that's how I understand it after taking a number of differentials apart and re-assembling them.

and just for shits and giggles, us2bwrx, why don't we check the level and condition of the diff. fluid?

this is the 3rd bit of incorrect information you have posted regarding our cars. at this point, i'm going to suggest you learn more about it before continuing to try and offer others advice. there are many things about our car that are unique, and that even a long time mechanic may have no idea about.

the car cannot be driven with a faulty LSD. our LSD is a gear type LSD. at all times that the car is moving, the LSD gears are spinning as well. regardless of whether we are turning or going straight.

http://auto.howstuffworks.com/differential10.htm

When the torque going to each wheel is equal (ie, going straight) the LSD acts as an open diff. As I said, if a gear had snapped a tooth and/or the LSD had failed, the car would be nearly undriveable.


While we appreciate your willingness to help members, you can't post misinformation as members may not know that you are incorrect.


by the way, i speak from experience here as well. even before the experience, i knew how the LSD did/didn't work. I had a friend who snapped a tooth off on his LSD, and the car could barely be driven. And when you did drive it, it was louder than all heck and the car limped along. Further driving only grenaded the LSD and diff even more.


you're searching for a solution in the wrong place, and steering members in the wrong direction. there is a different solution for the problem at hand, and it does not involve the diff.

Yo wis.....I had posted in a thread somewhere the procedure for re-doing the axle nut.

Can you hook up a link here?

oh, sorry about that, if i did direct other members to the wrong direction.

But the information I gave is not a wrong information.

I'm just giving my opinion about the problem. The points that I would start looking at if I get the same problem.

I mean I am a mechanic and that is how to solve the problem, isn't it?

First, suspect the possible faults and narrowing it down to the one, right faulty part.

Honestly, I haven't had an experience or seen a faulty Torsen-type LSD, so I guess I could be wrong. But hey, trial and error, right?

Oh, well, truely, sorry again to get you all worried about me confusing other people. However, as long as the car gets fixed and runs great, I'm happy, and everybody's happy, right?

So I guess we will just have to wait for him to get back and tell us what Honda guys did to fix the problem.
