Default Different names for Posi rear carriers

davids2toys Dave there are about 10-15 different posi carriers for sale that all do about the same thing. This is to apply power to both rear tires evenly. There are gear types, clutch types, cones types, heli gear, and air types. Your rearend is a clutch type unless ERA put in an aftermarket. For the best preformance out of the posi, change the fluid every other year. Remove the cover and clean the best you can. refill the rearend and drive. THIS is important, go to a parking lot and do tight circles in both directions. This gets the fluid between the clutch packs and the new friction modifier on the discs. I do about 5 and 5 2 times. best test after this is to wet a patch on the road and do a small burn out to see if both tires spin. The water makes it easier on the diff and car to check. The other way is to get a person to hold the other wheel and measure with a torque wrench how much resistance there is before the diff carrier slips. Would need to find the spec on this from my manual. Clutch packs due wear out over time or the springs inside the rearend get soft. I spent the money and went with a Locker rearend that is mechanical. No clutches. It is harder on the street and sometimes drags a wheel around a turn. Other thing is a rearend cover to help strengthen the carrier caps and stop cap walking. This is more for abuse or racing than street cruising. I over build any part I can because of track racing and autocross. As for the tranny fluid, new trannies now run automatic trans fluid in them. It's all how the trans is setup with clearances and wear and tear. I also think it's about how good the trans gets fluid to all locations, lubes and cools gears and bearings inside the case. I couple of guys run coolers and pumps for helping cool the trans. I have a kit for this buit have tryed just a small 4" blower fans to move the dead hot air from the tunnel of the car. It seams to help the rear inboard brakes as well to push out that hot air also. Rick L.

Good info Rick, thanks.
Did some checking on the MOROSO climbing gear lube today, the MOROSO engineer said it is 80-90 wieght, GL-5, no posi fluid added. he would definately recommend it for the rear end plus adding frition modifier, but a big NO for the toploader because of the GL-5 rating...needs to be GL-4.
With the rear, how much friction modifier should be added? I have an old 8oz unopened bottle of Amalie on the shelf, but i read somewhere this was not a good choice to use, but I forgot the reason why???

There's nothing wrong with Amalie -- it's good stuff. Here are the specifications for the Jag/Salisbury differentials that ERA uses (in both the Jag inboard and ERA outboard braked flavors):

Quote:
The filler and drain plugs are square. Fill to about below the bottom of the hole with Moroso climbing gear lube, SAE 90, part number 34800, mixed with 4 to 8 oz. of Amalie limited slip additive (part # 505-6775). If the above are not available, you may use 80W-90 GL5 lubricant with an equivalent limited slip additive. If the limited slip seems to be sticking (ratcheting around sharp corners), drain add refill, replacing the Amalie additive with 2 tubes of GM additive 1052358.

why not just visit your Ford dealer and buy a bottle of the motorcraft friction modifier additive. You add the whole container, it's about 8 oz.

Where did you find this?

thanks...Dave

Ratcheting of the rear used to have its own section in the super-secret part of the site reserved for owners only and lubrication details were outlined there. The last time I accidentally posted a direct link to that area Bob P. came by my house and threw rocks at my windows (broke two of them, in fact). But, as luck would have it, that info is also included in the "free version" of the ERA manual that is available to all. Click here: Download instructions for the manuals and web site and then click on the Free Assembly Manual for the 427 to download it (it's in PDF format). Then go to page 150 and you'll find it there, along with the capacities and suggested lubricants for transmissions as well (like the Toploader). I don't know what the true viscosities of any of the recommended stuff is, but I wouldn't second guess the manual since Jag based rears have been used exclusively in ERA cars for the last thirty years or so.

Very good, thank you. I love that ERA site. I have found a lot of great info their in the past
Their info for the tranny goes against what I have heard about Toploaser do's and dont's...specifically GL-5 and synthetic being OK

I found GL4 at NAPA about 2 years ago. Haven't read all of this thread but if you are looking for a source for GL4 check there.

Well, I don't know the answer to that either. I have a TKO600; but if I had a Toploader, I would probably just ring up David Kee and then do whatever it was that he told me to do....

I called NAPA yesterday and pick some up today, I don't know if this is the one you are talking about. It is called STA-LUBE and is made by CRC.
Multi-Purp[ose HYPOID SAE 85w-90 GEAR OIL.
API/GL-4
Part # SL24229
This was the only stuff that was pure GL-4. I am not sold on using it yet, but I grabbed it because they only had two bottles. I can always return it. Even the weight was weird, 85w90, hmmmmmmm.
They had the REDLINE MT-90 right next to it...I was tempted, but the synthetic is suppose to be NG. I guess I will just get more knowledgeable and then finally make my decision.
