OS giken install, HELP?
I'm installing the OS Giken LSD into my base. I got a new flange that I was told I'd need and I think I'm ready to roll. BUT, can I re-use the bearings from the old diff? Press them off and back on the new LSD. Thoughts?

I have access to a lift as long as I need it so not too big of a deal. The car has just over 20k. They look great, spin freely with no noise. Tempting...
Thanks for the advice guys!

off topic: I remember when I got my 4x4 4Runner re-geared the kit my gears came with had new bearings. We tried to press the new ones off but they exploded lol. We ended up using the original bearings and I haven't had an issue for the last 40k miles

I just did an OS Giken Super-lock install 2 weeks ago. If you want to reuse your bearings you'll need a large bearing separator and at minimum a 10 ton press. I picked this one up at HF and it did the job perfectly (http://www.harborfreight.com/large-b...ator-3979.html). There is a bit of a trick that you may need to do w/ 4 equally length 3/8 bolts to brace the separator against the base of the press, but I think it all depends on what type of separator and press you have. I tried using a gear puller rated for 5 tons but it couldn't cut it.
I still had the original open diff from my '07. It had less than 200 miles on it when I swapped it out w/ a VLSD pumpkin. I reused the bearings and kept the oil seals. Bearings were $73 each from my local dealership w/ a 5 day lead time.
Also, I ran into a problem w/ the stub axles. I called up OS to verify. If have an mid-05 or newer Z, the stub axles on the open diff are the incorrect ones intended for the current Super-lock. They are the tapered ends. You want the flat ended stub-axles that retain the C-clip on it's shaft. The distributor didn't know this and I ended up buying it. I was able to reuse one stub axle (driver's side) from my VLSD and machined a slot to hold a retaining clip.

Just replace the bearings, simple and worth it.
Drivesolo , so the machine work was good to go for you too?

Yep, just one stub axle. I scavanged the other one off of my VLSD. I finally got around to writing about my installation:
