Gears

[agamble]

I have searched around the world wide web but have not found a direct answer to my question. I am wanting to know if the gear set out of a grand cherokee lp dana 30 with be compatible with the lp dana 30 that is on the front of my comanche? From what I have seen it appears that it should be okay to swap as long as both are lp. Any input or comments would be appreciated.

4x4 Comanche were all Hi Pinion Dana 30 from factory, if someone has replaced your axle with a low pinion, then yes the gears will work.

^^^ What he said.

 

For reasons lost in the mists of time, Jeep was rather schizophrenic regarding their use of low- and high-pinion D30 axles. The YJ Wrangler was (IIRC) high-pinion. The TJ Wrangler, oddly enough, was low-pinion. The ZJ and WJ Grand Cherokees were low pinion. The early XJs and all MJs were high-pinion. The XJ was changed to low-pinion for the 2000 and 2001 production years.

 

So ... if your MJ really has a low-pinion front axle, it's a replacement. If so, you can use gears from a Grand Cherokee low-pinion axle.

 

If your front axle is a replacement, it would be wise to find out what year and model vehicle it came out of, because most likely the hub/bearing units, rotors and calipers will NOT be the same as what your MJ originally used.
