Default Grease for */C Needle Bearings?

Just wondering what the appropriate grease is for the needlebearings on a 95 M62... getting ready to throw everything back together, and want to make sure I don't cause it a nice premature death by having lost some lube up in there...

This is a special grease. Available through Intense, ZZP and Rolling Performance.

If you're over 100k, you should be replacing the needle bearings, not re-greasing them. They're quite affordable.

I'd love to, but it'* my daily driver and I'm very short on time. One of those unfortunate things where it just needs to get done, sadly.

<edit>

But out of curiousity, what are the specs and recommended manufacturer? If it didn't take *too* long to get them here, as it looks like I have to mail order grease, it might be a possibility.

Hmm... they mention it'* the same as what GM uses, but through a different vendor. Curious as to what the actual grease is, as I'm sure it could be had for less than $10 for half an ounce...

You would be shocked at the price.

The bearings at www.rollingperformance.com are pre-greased. Order now, have them in the mailbox in two days. You'll need to drill/tap the pockets and use a grease gun to remove them.

The grease itself is VERY expensive. I don't recall exactly, but I did price it once. You'll want a group-buy for it.

Read that rebuild page the other day - very informative.

I'm trying to dig up the type of oil right now, we'll see how far it gets. I've put a request through to Rogue and ZZP, but I would understand if they weren't too quick to shout out to the world what it is. I've also contacted Magunson, and talked to their lab techs who rebuild all of the Eaton */C'*, and they don't know either - they come in pre-lubed, and when they need to add a little bit (for whatever reason), it'* provided in a package from Eaton without labelling. I just put a request through to Eaton'* performance division to find out what it is as well...

So hopefully, at least 1 of the 3 will be able to come through, and I can try to find a more local source. If not, I'll probably buy some bearings today, and explain to the wife that she has to go another several days w/o her van...

Oh, and get myself some access to a decent size press. We've got them here at work, but getting an */C by security isn't always the easiest thing in the world to do. Not impossible mind you, but difficult.

I'm thinking I'm going to have to go the grease route for now, and if I ever decide to start having fun with this car, I'd go back and do the bearings. Of course, at 190k (miles), that'* a little unlikely, but since I paid so little for it... who knows. It'* very liberating having a beater. This partiuclar one was had for $700, because the previous owner knew nothing about maintenance... it was low on */C oil, firing on a whopping 4 cylinders (bad plugs/wires), and several vaccum lines were disconnected - including the vac modulator on the trans, causing the almost brand new reman to feel like it was going to die. About $100 of TLC, and it ran like new (and until the LIM gaskets blew through, it still did)...

Anyway, enough of that rant. We'll see what the grease will cost (I expect it to be nasty...)

Sure. LIM gaskets failed. Started to pull it apart, and as it so often happens of cars with this many miles, I just started finding more and more things that needed to be fixed... next step was the */C coupler, as I could move the pulley more than a 1/4 of an inch without the rotors moving.

In the process, the rotors came out of the housing... now they need to go back in. But I'm not too terribly interested in adding several more days to the project (and keeping the car off the road for that much longer) and replacing the needle bearings. I don't have direct access to a press, and the procedure (while well documented) for replacing the needle bearings suggests to me that there'* a decent chance that a slipup could leave me in a far worse position than if I were to just put it back together as it sits. Drilling a might bit too far, or mis-aligning the tap, or cross threading the oil fitting... can I do it? Sure, I could pull it off. But when I'm working against a time table, it'* easy to slip - and again, since this is my DD, I really don't have time to play.

Now, if I had a spare */C and LIM (and heads for that matter), I'd be having a field day porting and replacing everything I could get my hands on... unfortunately, that'* just not an option right now
