I put the AMSOIL Series 2000 75w-90 (code TGR) Synthetic Gear Lube in both frt and rear ends.

You can also use the Amsoil 75w-90 (code AGR) Synthetic Gear Lube...it's about $2 cheaper per quart.

When I do it again, I'm gonna use the AGR stuff....I don't tow alot and don't see the need to use the Series 2000 stuff..I thought it would help with fuel mileage, but it hasn't.

 

I have never heard that getting oil on a reuseable gasket is a no-no. It is made from what appears to be the same material as rubber o-rings. Many instructions for o-rings and oil filters specify you put a thin coat of fresh oil on them. An example would be the oil filter cover on my ZX 11. A new rubber o-ring comes with the filter and the instructions say to coat it with a light coat of fresh oil. I did not completely remove the front cover when I changed my front differential fluid. I just loosened the bolts let it drain, retorqued the bolts and refilled. I have no signs of leaking. I did completely remove the rear cover but there was no need to. The magnetic plug caught what little metal particles there were. None were lying in the bottom of the differential. In the future I am going to just pump it out and wipe the magnetic plugs off.

 

I take it that this magnetic plug, which I admitted have not looked for, does not help drain the fluid? Now why couldnt it have been optimally placed to provide for both functions?

 

No way, that would make it way too easy. How do you say bean counter? Strikes again and again and again and again and again! Yea that's what it is, the Energizer Bean Counter. Oh well at least we don't have major problems like over at the other camps. We have to search for small annoyances to complain about.

The magnetic plugs we are talking about are the filler plugs. They did do a good job of catching what small amount of metal that was in my diffs. But it sure would be nice to have that drainplug on the bottom of the AM axles like the bowtie guys have.

 

Bulabula,
Here's how.....Wipe it off......... when you just loosen bolts and retighten, your retightening the lube right into the gasket, cant really get in there to wipe gasket clean with the cover just loose..

 

This info is just what the ******* told me when he pulled my diff cover? I normally pump mine out with my oil pump for my boat oil.

 

Dean,
Glad to have you on board. I've lurked around on the TDR a bunch and have read many of your posts. You'll be of great help here and a welcomed new member.

 

I f you look at the under the Dodge AAM pumpkin, you'ss see a large flat area cast for a plug. It was only a matter of drilling tapping and adding the plug.

The Mag Hytek takes care of it.

 

I put the thick Amsoil 2K in my front and rear. I don't think front was recommended but I did it anyway (woops).

It ruined my front pinion seal in a hurry (timing coincidence?) but the ******* fixed it for free.

All I know is that my rear differential gets HOT towing.

 

Are you saying the amsoil ruined your pinion seal?




I am currently looking at some leakage, rear > front, that I have been told was normal for a new truck. I have cleaned it now at 11,000 miles and if it continues I am considering dealership check again. Not bad enough to drip, just wet about 3-4inches back.
