Are there any steering knuckle and/or brake upgrades for 2wd comanches?

Take a look on NAXJA about the WJ conversion. It's a real popular conversion for those with the D30 axle which the 2wd beam uses the same outers and everything so it could be used as well.

I agree, the WJ front conversion would be the way to go. Youll need to make sure you get knuckles from a 2wd WJ so you have the right stub axles to keep the bearings together. Though the WJ has a different bolt pattern than the MJ, so that will have to be adressed with either adapters, or having the the rotors and hubs redrilled for the correct pattern. Another issue is that your 15 inch wheels may no longer fit over the calipers, so some 16 or 17's may be in order. One option might be to retain the WJ front bolt pattern, and use adapters on the rear, as the MJ rear is a little narrower than the front already, and then use a set of WJ wheels all around.

 

If doing this, youll also want to swap to a WJ brake booster and master cylinder, or 96 XJ dual diaphragm booster and master and do away with the rear height sensing brake valve, and install a normal or adjustable proportioning valve. This combo will make a huge improvement over stock. And if you could get rear discs too, that would be even better. There are ways to do all this. Good luck

A stock rear axle is (almost) the same width as a stock front axle. It looks narrower because our bodies are a lot wider in the rear.

 

Going with WJ knuckles, since you will get new rims anyway I would look for a set of stock WJ, WK, KK or JK wheels. They all have the correct 5 on 5 bolt pattern, are all 16" or larger to clear the larger brakes and will have the corect backspacing. Then on the rear run a pair of the Spidertrax JK conversion adapters.

Cool, any year WJ will work? I'm already thinking of upgrading to the 8.25 with rear discs in the future.

Any year WJ WILL work. Though 2wd ones may be harder to come by than 4wd. One trick with the 4wd ones if you can't find a 2wd, is to take apart the CV shaft and just leave the end stub shaft in the knuckle to keep the bearing bolted together without having the rest of the axle.
