Jeep Commander Help!!

All caliper bolts, etc are tight as I had to pull it all apart to put the cv shafts in. Yes it does have upper and lower control arms but when I pulled the steering knuckle loose all of the bushings are surprisingly tight for having 105,000mi on it.

Dave, I'll pull the front skid plate and check the front d/s. I have to find the axle ratio anyways.
There are a few diffs for sale on ebay for very reasonable prices. I'll probably end up purchasing one of those and doing a complete overhaul on it, then install it.....if it's not the drive shaft, lol.
