Here is my post from h-t:
Well, as I sit staring at my brand new Quaife that just came in from camp1320, I am reminded of the brand new OBX LSD that is installed in my tranny right now.
Here is my review of the OBX LSD:
It was .033" wider than the stock unit. The stock shim in the tranny was .057". Fine. So I need a .024" shim. I go to Honda, and what do I find? Their thinnest shim is 1mm, or .03937". Shit. Ok, custom machined shim time.
Now I have a .024" shim. Cool. Time to press on the bearings. Fuck!!!! The god damn diff bolts stick up so far that I can't press the bearing all of the way down on the ring gear side. I had to pull off the brand new carrier bearing, and remove all of the bolts that hold the diff together. I find that one of the counterbores for the bolts was not finish machined. Time to grind all of the bolt heads thinner for clearance.
Now the bearings are on, and It's time for the ring gear. You must be kidding. The OBX diff body is so much larger than the stock diff, that all of the ring gear bolts bind when they are tightened. Time to grind .020" off of the washer head of the ring gear bolts. Now with the thinnest wall Snap-On socket I could find, I was able to assemble the ring gear to the diff.
It's now in the tranny, and time to insert the axles. No problems.
First drive, what the hell? I just installed remanufactured axles, and it shudders badly under load. Ok, I've gotten bad axles before, so back to the parts store.
Came back with brand new axles. Normal installation, no problems.
Out on the road again, same shudder. I pull it into the driveway and jack it up. I can seriously move the axle cup within the diff .110", as measured with a dial indicator.
Basically the axle bores are tapered, or way out of tolerance. My OBX LSD is a piece of shit. Many people have great success with the B-Series unit, but the D-Series models are really fucked.
Yes, I will be pulling my tranny on Saturday and installing my new Quaife. I thought I could save $400 by going OBX, but now I have spent over $600 more considering I ended up purchasing two new sets of 80mm carrier bearings.
I put my new Quaife in yesterday, and it was worth the time/effort/expense.
