Go 75W-140 for towing. Regular driving, go with the 75W-90. I switched to Valvoline Synthetic. No friction modifier required and the LSD works great.<br>[/quote]<br><br><br>What about Friction modifiers for Limited Slip??

It seems no two clutch packs are the same, some chatter, some don't. A true synthetic lube will be a PAO/ester basestock, with the esters being the "internal" friction modifiers.

Ok, that's a 3500 I suppose.<br>Front: 7.6 pints (you'll need 4 quarts)<br>Rear: 10.25 pints (5 quarts, plus the remainder of the last bottle used in the front.

I just changed mine recently, and picked up a Suction Gun while I was at the parts store.
Think of a large automotive type turkey baster.
Made filling the diff after buttoning up the cover a breeze.
Very little spillage, and no figuring out how to make the fluid go uphill into the little hole. : ;D
A very worthwhile investment.

Re:Diff Fluids
Hi John, I'm sort of your neighbor, I live down in the Placerville area. I'd be happy to show you how to do this, it's quite simple as has been said already. <br><br>I would make the following suggestions, if you are so inclined and have the $$ to spend at this time.<br><br>Since you have to completely remove the stock diff cover(s) to change the fluid [thanks whoever > ] this is a great opportunity to go to an after market diff cover. The two most common are the Mag HyTec and MagView covers. They range from $200 - $250 each though. There are covers available for both front and rear diffs, I have a MagView on both ends.<br><br>Also, this is a good time to think about going to a synthetic lube, or at least a top quality dino lube such as Lubrication Engineers (I forget the right product for diff lube).<br><br>PM or email me if you'd like to get together to do this.<br><br>Tom

Re:Diff Fluids
TOM - as a decent alternative to the expense of an added aftermarket cover - consider the simple drilling and tapping for a plain pipe plug at the lower edge of the stock cover before replacing it - I use a 1/8 inch plug - which is nearly 1/2 inches in actual hole diameter - it drains quite well, and sure is cheaper than the aftermarket stuff... Just be careful of placement of the hole, and avoid any possible interference with internal rotating gears...<br><br>Cheap and easy (the plug, not me)(welllll, maybe...)

Re:Diff Fluids
.........I assume that Mag-Hytec provides enough clearance for the track bar rod end on the frame, but If you need to install a Luke's Link you may have clearance problems.
Man, hitting a brake drum? That sounds like fun.. :

Re:Diff Fluids
Yeah, well at least I dodged the tire that came first! <br><br>Actually, I was pretty impressed at how the diff cover held up. Pretty tough stuff!

Mine takes a full six quarts with the stock cover. I do get the half quart or so out of the sludge in the bottom though.

Re:Diff Fluids
OK it's done!! The final number is:
4.5 quarts after removing the cover (rear).
I used the total emjay solution: valvoline durablend 85W140 and the Ultra Grey silicon from Permatex to seal the cover.
Thanks to all who wrote in.
