I had a jeep cherokee DD that had 300,000+ miles on it when the open diff spider gears locked up and snapped the center pin. its funny when your driving along and your tires and axle shafts pass youI am no expert but it it siezes, your diff will lock up, if parts of it breaks, the chunks will tear the diff apart, and you will feel it, either way, I think you would notice if it broke. Any one know if it is possible to wear the helical gears out and not notice.
Today I attempted to get to work using my GC even though my street is still covered in snow and ice! (God damn town) Anyways, I backed out of my driveway, went over a little speed bump of snow and ice, and my car got stuck!
I wouldn't go anywhere in 1st or 2nd. Traction control on or off. Idling or giving it a decent amount of gas. I heard my tires spinning on and off but here's the strange part, when I went out to check things out, only my back left tire left a black skid mark on the snowice. It's as if the right wasn't spinning!
I'll have to get someone to check it out when I give it gas but this isn't the first time it seemed like 1 tire was spinning. I thought the whole point of having LSD was to distribute power equally to both tires?!
Could it be possible that it's broke or maybe the damn dealer stole it off to screw me? Seriously though, is it possible that it could've been disabled or not installed? Thanks
i thought applying the E brake trick didnt apply for LSD ??? ( trying to learn a bit here too)
sorry maybe should have elaborated! I was aware of the E brake thing....... as my car continues to get stuck in these canadian winters! however when talking randomly to one of the Hyundai mechanics, he was explaining that the E brake thing doesnt work on LSD differentials and only works for an open differential! So completely understand the mechanics of a differential, I just had one of their mechanics saying it doesn't apply to a Genesis' LSD
^^None of this is right.I know on some rear diffs than they can engage (as if one tire was starting to slip) when the fluid needs to be changed. From my experience they sound just like some of the bunk LSDs that are out there on the Genesis Coupes.
I have no idea for wearing though, I've never worn out or driven a car with a worn out LSD or even differential.
What do you mean "not apply for LSD", what else would it apply for? A torson type LSD uses a TBR and that 'multipies' tq to the other tire. You can wiki it if you don't believe me. Putting the brakes slightly increases tq to the tire.
It is possible that is doesn't work for a viscous LSD or maybe a clutch pack LSD (since you need a lot of tq to lock that up) though I haven't studied as much on the other types.

There is a TBR (torque bias rataio) probably closer to 4:1 and even 100:1 it might not move. As 0 times 100 is 0. If your slipping tires has no tq, your other tire won't either. One technique is to put the parking brake on a bit so the tire has to work to move giving it tq and supplying that torque to the other tire..... though you might have both tires slipping still. I have been in snow with 4 tires slipping on 4x4. Deflating your tires a bit can help, though winter tires would be your best bet. Sitting there flooring it isn't the best aciton either, you just melt the snow and turn that water into ice making it more slippery.
You can't 'disable' a torsen LSD, it is mechanical, and I highly highly doubt it was mistakenly uninstalled.
^^All of this is Right.Our track edtion comes with a LSD (limited slip diff). Basically it will allow a limited amount of slippage between the two wheels. Being that its not a full lock up rear in like what your thinking of, if one tire looses complete trackson the other tire will not spin. Poor man tip if you get in this situation again pull up your e-break to help the limited slip do its job. Another tip don't spin in snow and track models came with all performance summer tire not all seasons like our brothers. So they suck in snow
E-brake or plain brakes applied to a slipping Torsen LSD will lock the LSD so it can try and send some torque to the "open" wheel.Thanks to everybody for the help! I never knew about the EB trick. I refused to buy winter tires. I think I would much rather buy a winter beater. I def need new tires as the treads are pretty worn but I'll save my money for performance tires in the spring.
