I know what you mean brother, life just has a way of gut-punching you at the most inconvenient times.
Well, if it was me, I'd roll-up your sleeves and see if you can't get the ball-joint taken care of on your daughter's Liberty.
Do you know anyone that could maybe give you a hand? I wouldn't think a replacement ball-joint would cost that much if you can try & tackle it yourself with an extra pair of hands.
While was multitasking and letting the POR 15 dry on my Grand Cherokee, I gave my daughter's Liberty an oil change. Now that I got a better look, it isnt the ball joints but rather the tie rod ends which should be easier. I have been soaking them in PB Blaster. The Liberty has the same setup as the Commander. And like my Commander I went ahead and checked the boot at the end of the driveshaft and sure enough it was cracked open. Only this time there is no warranty. I ordered a CV Joint kit to repair instead of replace along with new tie rod ends. I do hear a low moaning sound when driving and when coasting. After more research it looks like its most likely the wheel hub assemblies/bearings.
Now I have an actual Commander question. I needed new tires and I got a great deal on Wrangler Moab wheels. I went to put them on and one just clears the front caliper but the other side rub one part of the caliper bracket near the bottom bolt. They are Power Stop calipers. Would different calipers clear better? I dont know much about wheel spacers but I dont need much more clearance at all. May 1/4". I started looking at some and It looks like I may need longer wheel studs? The Power Stop calipers are starting to corrode. So much for powder coating. Also I saw they make a one piece caliper and bracket but it was some generic or no name brand.
