    limited slip differentials

    what does overhauling an lsd involve?
    i heard that if it takes too much punishment during things like donuts and drifting it wears and needs to be overhauled

    im assuming this doesnt mean a replacement since that will be too costly, does it involve changing out the plates? gears? i have no clue

    please help

    It would involve tearing down the rear end and replacing the clutches. It can be difficult if you have no experience, and you have to be sure everything lines up correctly or else you will destroy the rear. Drifting can cause wear faster than normal driving, but that's like saying if you don't eat you will starve. If you have no to little mechanical experience, I would take it to a professional. If you have atleast a couple years experience, I would do it with a professional looking over your shoulder making sure you don't screw up.

    Overhaul

    Overhaul means:
    1. periodic maintenance on a car or machine
    2. activity involved in maintaining something in good working order.
    3. make repairs or adjustments to

    you can look it up in a dictionary, its not a specifc term just for Limited Slip Differentials (LSD), you can overhaul your car engine aswell.

    So to overhaul an LSD it means to repair it and maintanance, in which way? depents on the maintenance it needs and the damage.

    Lots of informatino and no knowledge ..... not one of your better replies N4S !!!

    Anyway, there are different types of LSD, so you could be facing anything from a possible DIY to a "specialist only" job.

    BUT even the possible DIY is ONLY if you have the tools and experience to properly set up bearing end float, pre-load, slip and many other areas in variable LSDs

    Tsuchiya Keichi said in drift bible:

    "If you drift like five days a week like I used to, you need to overhaul your LSD once everymonth or so. This means if you go drifting once a week, you need an LSD overhaul at least once every eight months or so. "

    i wanted to know what it involved, i knew in that context it prolly meant having to either repair or replace the clutches in the lsd but i didnt know the exact process

    Differentials

    I did some research on Lim. slips when I wore out my "positraction" in the mustang.
    There are a number of different differential types, most have clutches but a few don't. Most notably the "tru-trak" which has spiral cut gears which shift the torque to the wheel with the most traction. (Which is what I went with)
    I assume evrybody else knows what your car is but unfortunately I don't so I don't have a clue what kind you have.

    There is a pretty good list of types at Randys Ring and Pinion.
    If you have set up a standard differential you probably can rebuild a limited slip, but it won't be easy. I've done a couple of stds. but never tried a Lim slip.

    the only types of limited slip difs i know of are vicous ones which are usually used as center diffs, torsen which is hydraulic or electric or something, and the "normal" type (i dont know the actual word) which has a clutch pack spring set or somethign liek that, sorry for my crappy ass terms

    There are as many variations of LSD than there are engines
    But they use either gears, plates or viscous. Each have advantages and disadvantages and over the years designers have pleyed with combinations. Life's never simple

    the LSD in an FR car is at the rear axle right? instead of combined with the gearbox like the Civic EK or integra have... i'm confuse..

    Yep, the LSD has to go between the axles as it's controlling the drive to each wheel to prevent one spinning under no load.

    basically LSDs allow more power to transfer to the non slipping wheel compared to the one slipping, but if the wheel was in the air where no torque can be applied to it the other won't get any either. unless of course its a locking dif which locks the 2 wheels of the driveshaft together, or if u apply the brakes which allow some torque to be let through

    when the differential and gearbox are both located in the same assembly the whole thing is called a transaxle, these are most often found in front engine front wheel drive cars, sometimes in mid engine rear drive cars

    That's true for torque sensing difs (TORSEN ) but for viscous and clutches they WILL drive the other wheel which has grip.

    Mid and rear engine cars - can't think of one that doesn't have a transaxle from the humble imp to Ferrari

    alot of people seem interested all of a sudden in RWD transaxles, the C6 Corvette apparently hs one, as does the 575 Maranello
