Base model, so it should only be an hour or two, right?

Install should take roughly 2-3 hours for a skill tranny expert, but they will probably charge you about 3-4 hours of labor. Something around $300 seems fair, since they have to install new bearings, seals, and load with oil, and they often have to remove or disconnect the exhuast system and a couple other pieces.

Yes.
I swapped out my oem open diff for a oem 350Z VLSD (might as well have filled a shoe box with $900 and tossed in a river). The oem FD is the same part on the open diff as the VLSD diff. The FD was simply removed from my open core and installed on the VLSD core. The only thing different would be the need for open diff stub axles, the mouting surface for the FD is the same on MT open diffs and MT VLSD diffs.

Thanks Sharif.
Thanks Sharif.
Once the gears on this ATB diff are bathing in diff oil, they're ready to roll, right out of the box.

Just got the Diff in from UPS today (thanks Sharif!), and I have the install scheduled for Friday. Can anyone recomend a good source for Redline 75W90 oil that I would be able to have in by then?

Sharif,
How did the Quaife installation go today? Any problems? Fit OK? Did you have to do any shimming? How does it feel on there, now? Did you take any pictures during the installation? Please advise.

I will definately post some pics.
No break-in is needed. But I imagine it would be a good idea to change the fluid after a few hundred miles, just to make sure there is no leftover metal material in the oil. I need to review the installation and instruction manual, as I am sure it will speak to the break-in process, if any. Once I recieve the diff, I will advise.

Same here. No installation instructions came with it. I don't think Quaife includes installation instructions. I guess they figure if you don't know how to install a diff, then don't try...

They don't come with instructions because they are basically a exact stock replacement item on a 350Z. There's not special parts or modification required, so the removal and installation is the same as what's specified in the Factory Service Manual. Even down to the lubricant required.

Well, that makes a ton of sense, Briguy.
It looks like my dealer will install my Quaife ATB Differential for me. They agreed to charge on a time and materials basis. I wonder if they'll have to use shims? I hope not. By their own admission, they are more accustomed to installing complete/sealed/pre-assembled factory units. If they have to build or shim anything, I think I'm screwed!
The dealership is trying to source the bearing/races for me now. (The oil seals are apparently readily available.) Yesterday, they told me there was only one pair of bearings/races left in the USA, but one dealer had only one of the two bearings/races, and another dealership had the other one! It was not known whether either dealership would sell what they had. I should find out tomorrow. I got my fingers crossed.

Very true. Most diffs will come with instructions in terms of break-in, recommended oil, and disassembly diagrams. The Quaife is a totally sealed unit and should never be dissassembled...should be a drop in affair, and should not require any shimming.

I was looking at the FSM for this procedure and there sure are a lot of special tools indicated. Tools to pull/install the bearings, tools to pull/install the seals, tools to lift the diff out of the case, etc. etc. No thanks, I'm leaving this up to a pro with experience.

A screwdriver and a hammer make great "tools" to pull and install seals. And hands make great tools for lifting the diff out of the case.
I know what you mean..it's not a piece of cake..but nissan seriously has some really pointless tools that they prescribe for a lot of the work on their vehicles.

A lot of those tools are uneeded. I thing Nissan is trying to sell expensive tools!!
They even have a $5000 accordian lift for lowering motors down from the bottom of the car. We just use a lift, engine hoist, a pallet, and a tire.

They must have some kind of contract with Kentmoore.
