Can only be warped discs, seized/stuck calliper(s) causing uneven pad wear, worn wheel bearing, or loose wheel nuts really.

I'm leaning towards seized/stuck callipers. You can get a calliper service kit for around $30 for both fronts from most good brake places, and they are easy enough to fit/service following the instructions that come in the packaging.

Just warped rotors, we all get it, I run DBA slotteds, and theyll be starting to warp 5000k's after a skim.

Id be leaning towards warped rotors also. Pretty common with the ABS apparently.

it is not the ABS that causes it on the hat type rotors if you don't get all the scale etc off the mating surfaces before puting rotors on it runs out of square and warps. here is an article from DBA that explains it http://www.dba.com.au/2006/techdocs/T026.asp

Yeah, JC has just about covered it but I'll go with a front wheel bearing.
