The OBX LSD is a knockoff of the Quaife for about half the price. OBX isn't the best quality, you get what you pay for. The Quaife is more expensive because their price reflecs the R&D that went into their LSD. The OBX is a direct copy, so that is part of the reason it is so much cheaper- just like any knockoff. I read plenty of horror stories about earlier versions of this LSD... axles being stuck, shimming issues, opening up a brand new unit to find metal shavings inside. Some people even upgraded the bolts & washers to beefier ones. There were a version 1 and 2 of this LSD, I was lucky to receive the new version (no exterior markings) that has been dubbed v3.0 from other sites I have read.
Notice the difference in bolts in the 3 above pics. Some have a small symbol in the center. One of the bolts even had the hex slightly off centered. The "12.9" on the bolts is the grade.
There's the outside of the LSD. Notice the lack of stampings or engravings. No logo or part # or serial# on 3.0.
6mm hex bit beeded for the outer bolts.
You'll need to clamp the casing to loosen the bolts. I used some sanding blocks so I wouldn't gouge the surface. Loosen them evenly.
Once you loosened all the bolts evenly, remove the cover.
Notice that there is one blank bolt hole, this has to match the blank area on the housing when going back together.
Initial pics... I don't have any of the older versions to compare to, so I can't say if anything has changed or improved. So I took plenty of pics so someone who has seen them both can compare.
Here the top set of outer gears has been removed and set aside.
Next the center gear was removed to expose the washers that everyone talks about. There is still a smaller gear in the middle that is holding the washers in.
Here is that center gear, notice that the beveled inner edge faces the outside of the LSD, where the axle teeth will slide in.
And behind that gear is the smaller gear, with a recessed lip that faces the inside center of the LSD where the washers are. It holds them in place.
So here is the top layer of parts that have been removed so far.
See the middle, the big gear has the beveled inner edge facing up to the outside of the LSD. Then the smaller gear sits under it, with the side that accepts the washers, facing down (where the washers would be)
With everything above removed, here's what you're looking at:
Next pull out this thing, lets call it a retainer siince I don't know a better term and it keeps everything in place.
Now I'm pulling out the washers and the small gear on the bottom (similar to the small gear on the top) that holds the washers together.
Close up of that bottom small gear and the inner lip (faces up) that holds the washers in place. This edge will face up when going back together, holding the washers in the recessed area.
This edge will face down when going back together.
These are the washers. Note how they are stacked, this is very important.

Washers and bottom small gear layed out how they were removed from the unit.
Here's what you're looking at now.
The second outer gear set removed.
And the last gear, the other axle fits into this one.
