Dana 300 Questions ?

[mx_scottj]

Will a Dana 300 bolt up too a AX4 in a 95 yj. I though at one time somebody has done this but not for sure.

It depends on what it's out of...

80 and newer CJ's had a circular pattern D300 with the right bolt pattern, but, the output will be on the wrong side. You can flip the case with modified shift linkage or a modified housing via a flip kit, but you'll have to oblong a couple of holes as they won't match the stock pattern upside down exactly. Further, the short shaft D300 in the 80 & 81 models won't accept the electronic spedo assembly on the newer YJ's. You'll want one out of an 82-85 CJ7 for the YJ speedo to work.

Also, I don't know what an AX4 is. If you're talking about the AX5 5 speed tranny behind a 4cyl Jeep motor, the spline count on the trans output is different from the input on the D300 so it won't work in that regard.

perhaps an AW4?

I thought that maybe too.

The same applies though as the AW4 and the AX5 have the same spline count on the output shaft.

just in case you meant the AX-15 5 speed behind the I6 you will need to get this http://novakconversions.com/ but at the same time unless you are going to run a passenger side drop axle you will need to get a flip kit.

Thanks for your replys. I have a 300 out of a 84cj7. But no need to flip because I'm going full size chevy one ton so the drop will be right on!

Flip kits are NOT required, save your money & get a proper adapter for a drivers side drop. Novak used to supply adapters for a Flipped D300 connection to an AX15, but I notice they no longer do that. The standard adapter (aka clocking ring) won't line up properly when you turn the case all the way around, but you could get a local machinist to make one for you.
