Did my caliper lock up?

[Knucklehead97]

So driving to work a couple weeks ago my truck all of a sudden started pulling HARD to the right. And then when braking it pulled really hard to the left. It also took a bunch of gas to get moving. Once I got to work I immediately realized my right caliper had locked up (smelt horrible) so I rode home with my brother and was going to deal with it the next day. Then when I got in the Jeep the next day everything was fine! Checked the caliper and all and it was good! Drove for a couple weeks and until today everything was fine. Driving today I all of a sudden got a weird wobble in the front end. Then BOOM my truck goes nuts in the middle of the road wobbling. Once I get pulled over and settled down I head back out to limp home. After the major wobble the caliper locked up again! And there was a squeaking noise coming from the left side for a little bit. What do I need to change? I was thinking

 

For the wobble; tires rotated, balanced, possible front alignment.

 

For the brakes; calipers and rubber lines.

 

The squeaking; hubs?

Check wheel bearings. If 4x4, it's a unit bearing hub assembly.

It's my 2wd. Wheel bearings are basically part of the hub, correct? How do I check them?

If wheel Hub assembly is good, one question, how long has it been since you flushed your brake fluid?

Is this on your 2WD? If so, read this:

Difference between inboard and outboard pads:

To give more info this IS on my 2wd and I forgot to add that I swapped a 98 XJ's front beam in a couple months back. Changed everything on the axle other than... guess what.... THE CALIPERS AND HUBS! I noticed with the hubs when I bought the axle that they didn't spin freely very easily like my old 2wd axles rotor/bearing combo did. I'll have to check them out some more. I'm thinking my problem lies in the calipers and the slide pins because last time I checked there wasn't much grease in them. And also I have never flushed the brake fluid in this Jeep as I have only owned it for about 8 months. Was going to flush the system when I did my WJ MC/booster.

Hubs and brake lines (ordered the Dorman ones off rockauto that have an extra 4" of travel for when I decide to lift a couple more inches) are on the way. Calipers will be picked up from Advance the day I do the work so I can bring the core up theres. A little confused with the hubs though. In the middle of the ones I bought there is grooves and a hole in the middle instead of there being a castle nut and cotter pin? What's up with that? The description said they were 2wd hubs.

The hubs I bought say they're for a composite rotor? I didn't realize that there was multiple types of hubs other than 2wd or 4wd?
