Dana 35 out and hello Dana 44

I am getting ready to put in the rear dana 44 with disc brake. Will this disc brake work with my current setup? It current have rear drum brakes. Will I need mod or swap or buy other stuff other than the e-brake cables? I have been hearing that the master brake cylinder or a proportioning valve needs to be changed for the brake to work properly. Please shed some light.

P.S- this is an 05 rubicon rear axle.

As I understood it your brake lines will work fine. I could be wrong though, so don't take just my word for it.

No mods are needed for the brake lines, you only need to connect then bleed them. You reuse the same brake proportioning valve as-is. No modification is needed like taking the o-ring out like you may read about. I did the same thing, converted from a TJ D35c to a TJ D44.

If you have taken the disk brakes off and have to remount them, be sure to get them on the right sides. Reversing the brakes will put the bleed screw too low and make bleeding them properly impossible.

Luckily, the brake fluid metal tube was still attached to the calipers and left it on when I removed them for axle painting. I used the fluid metal tube as a guide when I installed it back. Thanks for the heads-up.

Be aware you may need to slightly shorten your rear driveshaft as the D44's yoke is slightly closer to the transfer case.

Yea... I measured the dana 44 from the axle shaft housing to the middle of the yoke and got 11 1/4 inches using a right angle a tape measure. I don't know the measurement on the d35 though. Kind of hard to measure while still mounted to the vehicle.

I was told that I can get by if it is only a 1/4-1/2 inch difference.

It's about an inch if I recall correctly.

Cool...I hope I am within that range so I don't have to spend more money on shorting the driveline.
