Axle Gear Oil

[GREENMV]

I searched the Forums and am lost on this question. I am going to replace leaking right rear seal in my M1009. I know the TM shows adding 80/90 would It hurt to add a heavier weight oil? Is there any recommendations? I have no idea on this subject.

No you want to use the correct 80/90and add a tube of anti slip for the locker.

1009's have a locker? I thought the 08's only had them. If your talking about the gov bomb gm made. It shouldn't need an additive. It's not a LSD. Lockers don't require special additives.

If I recall correctly the M1009 with the Gov Lock does not require an additive. DO NOT use anything but the specified weight.

Thank's to all. I will use 80/90

its a clutch pack locker... thats the type you NEED the stuff in. In most cases if it was used before you really dont need it because it has soaked in to the packs... but if it has been flushed a few times use it. Cant hurt it.

So it's a limited skip then. Lockers are gear.

Per the lube order, the M1009 does NOT require the additive. The lube order specifies the additive for the front diff of the 1028 and 1031 only.
