Hello All,

I am currently in the process of building a new Dana 30 including the WJ knuckle swap. I just came across someone on fb marketplace selling a dana 30 with mile marker locking hubs for a really good price. I would love to have locking hubs but passed due to the price of the conversion kits. My question is, is there anything I need to know about installing this with the WJ knuckle conversion or will everything mount up right? I truthfully know nothing about locking hubs as far as install.

 

How about contacting Mile Marker, tell them the part number, and ask if it will fit? That is what Id do in your situation. Consider what axle, length and diameter, spline count is required also, Some hubs may fit, but require non stock axle size. You may even obtain assembly instructions from them! If your doing the disco elimination, you will need at least one new axle at minimum.


If you do disco elimination you may need a different right hand axle oil seal, in which case beware that the seals sold for this purpose are substandard, and are very prone to leaking, so dont bother using that seal, instead do as done in link below for a superior seal....
