Can anyone tell me about the LSD's in an R33 GTS-25T? I have read that the manual cars come standard with an LSD, however after fitting new coilovers recently I've found that if one of the rear wheels lifts up such as when going up a steep driveway the wheel without contact spins endlessly without the LSD ever engaging. Is my LSD worn or how can I tell if I actually have 1???

Cheers

There MAY be a small tab on the rear of the housing with "LSD oil only" written on it, or something like that.

Alternatively you can jack up the rear end of your car.....spin ONE wheel and if the other wheel spins in the SAME direction it is LSD, if it spins in the OPPOSITE direction it is open diff.

To check the condition of it have a mate hold one wheel while you spin the other, if there is little or no resistance then it is basically stuffed........of there is reasonable resistance you have a decent lsd.

Hope that helps

Viscous LSD's don't immediately lock when one wheel is spinning, they come on gradually as the viscous fluid heats up. You can only really test their action after you have been driving (and using the limited slip) for a while. ie; don't walk out in the morning jack the car up and expect to get a satisfactory result.:P

i think its time you invested into 2way or 1.5way lsd, its diffinately worth while!

We ran one of ours as a BOC locker on the weekend, while we wait for a proper one to arrive from Nippon.

Worked a treat...

There are only 3 types of viscos LSD, 1. New ones, 2. Ones that don't work, 3. Welded ones.

Should be able to score yourself one for round $700 S/H

TT

Jase, when i had my factory viscous lsd and super hard tein coilovers, id also spin one wheel real easy while going slowly through driveways. In my case the suspension was so stiff that when going through a driveway angle one of the rear wheels just lifts off the ground, allowing it to spin, and i would never feel an "lsd effect" in these conditions. Launching however my lsd would work fine. Do a burnout, and id have two nice black lines.

As mentioned its easy to test, after a good drive give it some boot off the line and check your tire marks on the road.

    • I'm so far behind in the jobs I have to do at both work and home (including car) that I have become immortal. There's simply no way that I can die now.
    • Each to their own I guess  Me, I put just as much time into cleaning inside of the cars as I do on the outside As for getting wet, it is really no different than steam cleaning the carpets at home, apart from the cars carpet dries alot faster than the house, again, I only do it in the hotter months and leave the car opened up for a few hours As I only do it yearly, it is just before I do the diff and gearbox service, so I clean the carpets, then it's up on stands, wheels off, service, clean the undercarriage,  grease the bushings and do a nut and bolt check on everything  Disclaimer: I typically had all the time in the world to kill when I was working 🤣, so spending a full day or 2 cleaning, serving and "looking at stuff" was,  easily achievable, and a fun mental therapy day As for time to kill, I retired last Wednesday, so apart from my physical training, my days are filled with lots of random jobs around the house and garden...."Idle hands are the Devils something something" I am also buying a new house sooner rather than later, I'm actually looking at a potential property tomorrow, I'm looking forward to getting a car hoist as I'm starting to get to old to crawl around under a car, I can only imagine all the undercarriage cleaning and looking at stuff when that gets set up
    • Yeah, I'm not interested in wetting the carpets, and I don't care about brown dirt/dust that lives deep in the pile or underneath. It's not like I crawl around on them in my birthday suit or eat dropped food off them (because there is never any open food in my car). The seats are alcantara (cheap Chinese imitation alcantara, to be sure!) with barely 1" of foam pad behind the surface. That's not getting wet either. Any car that I would be happy to get the interior wet, I would not care to put the effort into.
    • We have one that holds 2.8L of water. On floor carpet that hasn't been touched in 2 or 3 years, will take a minimum of 2 fills of the tank to do a bedroom, and that's going AROUND the bed.   In the cruiser, I used an ENTIRE 2.8L tank, just on the front passenger footwell. But it had some fungus growing, and had been full of mud from being used as a 4WD for many years. I can do that floor again, and it will still pull mud out. However, the water now only looks dirty, not pitch black and leaving full sludge in the bottom of the tank it sucks back into. Oh, and, this is about a $1500 unit.
