diff fluid question for 06 crown vic police.....

[P555]

with a traclok rear end. Our wally world has synthetic shell 80/140. I know nothing about gear lubes and just want to make sure this will be ok. Thanks.

I run Amsoil Severe Gear 75W-90 with 4oz of Slip Lock in my CVPI with LSD.

80W-140 would do fine, just don't forget to add the friction modifier. Motorcraft Synthetic 75W-140 and friction modifier is what it comes with from the factory IIRC.

 

[P555]

Thanks for the replies. This friction modifier, is this sold at most auto parts stores?

 

[Falcon_LS]

I'm not sure about its availability to be honest. But I know a Motorcraft one is available through dealers.

Amsoil 75W-140 Amsoil 75W-140 LINK and Slip Lock

IMHO I wouldn't go thinner than 75W-110 LINK

Ill have to give them a call. Thanks.

XY-75W140-QL with a bottle of XL-3 is what the car had from the factory. if you take the cover off, use silicone to put it back on as there is no gasket for that application from FoMoCo.

RTV sealant would be a good choice I would imagine.

 

[P555]

Are you guys using anything to clean out the rear end after draining the fluid? Like an aerosol spray of some sort?

 

[bdcardinal]

bunch of brake cleaner.

 

[AzFireGuy79]

Check out Permatex The rightstuff. It works much better than most RTV sealants.

 

[chevrofreak]

Forget the RTV! I can not be more emphatic about that.

Buy yourself a LubeLocker gasket.

Been using RTV on rearends for years with not a single leak. Forget the gasket.
