Regear: what oils/ lubes do I need?

[SSgDan1009]

@grimmjeeper @CarbonSteel I read in a different post that the M186 doesn’t use Adventec; this is misinformation to me; what’s your thoughts?

Im planning to use Dana #10026645

Those are the wrong gears--they are for a JK and you need JL.

It could be (Advantek is only D35 and up). Since Dana lists the same part number, I would trust them over a reseller like Summit to have the correct information (the weird thing is summit specifically states JK and does not list JL).

Buy the Yukon shim kit for both axles. The Spicer does not include enough carrier shims.

Did you use Dana gears on your install?

Yes. M186 front, M220 rear, and the Dana master install kits didn't have enough carrier shims. The two sides of the carrier are different sizes, and I think the kits only have to 0.100", and I needed something like 0.105" on one side. My factory shims were something above 0.100" as well.

There is no Dana 35 any more. Or Dana 30 or Dana 44 for that matter.

The Advantek axles are the M186 and M210 front, M200 and M220 rear. Those are the axles installed in the JL.

Most parts stores get the names wrong. And most people, even on this forum (I am guilty of it too) call the JL axles by the Dana 30/35/44 name.

Don't get hung up on whatever name some under paid data entry clerk put in the sales computer.

Great info. Thank you
