Default Should I swap hubs or not?

I own a 04 sti with approx. 38K and im starting to have serious drivetrain issues and want some opinions on how to go about solving these problems. First my most urgent problem is a very loud metallic grinding noise that comes and goes, i suspect that its a front passanger side wheel bearing. Second is the common rear strut clunk which seems to be getting nothing but worse. The third is a slipping clutch which unrelated but if the car needs to be layed up to get the rest done mine as well do it at the same time...

Ight so now to the much needed advice, i 've read alot about hub swap's for the 04's to the 05+ bolt in front hubs and was thinkin since i'm due for a set of coilovers and now wheel bearing's.. will it be worth investing money into hubs, rims(want some volks), rotors and etc. to complete the swap..

I plan on doing all the work myself, my father is in the auto body buisness and im a marine tech., and have access to press's and such, but not sure how much more tooling id need to complete the job.. So i guess my question is, will it be worth the swap to 5x114.5 or should i put new bearings in my 5x100 hubs and get suspension for that setup? Im looking to have a reliable auto X capable set up that will be clunk free. Also anyone that has experience making the swap plllease chime in.. Thanks

Can anyone describe what a bad wheel bearing sounds like.. I'm fairly confident thats the issue but i have a faint clunk/tick as the car is moving a slow speeds, when moving at higher speeds it almost sounds like i have excessive tire/road noise and occasionally i will have a violent vibration that will come and go depending on my driving.

Thanks for the responses

Quick and easy test... jack the car up and grab the tire (one with suspected issue) at 12 and 6 o'clock and push with one hand and pull with the other. If the there is play then more than likely you have a bad wheel bearing.

What you describe sounds like a bad wheel bearing but, you also describe a bad driveshaft bearing, driveshaft yoke, or even a diff. It depends on where the noise/vibration is coming from. Don't let that scare you, just check the wheel bearings first. You can check by jacking the car up and moving (or shaking) the tire. Move it side to side, up and down, and rotate it. There should no (or very, very little) movement and the rotation should be quiet and smooth.

The 5x114.3 hubs are meant to be Subaru's fix to the weak 5x100 bearings. It is quite a bit swapping to make them work but, if you plan on new struts and wheels, then go for it.

I got under the car this weekend and checked the suggested spots to determine if my issue is a wheel bearing, when i checked for play by grabbing the wheel at 12 and 6 o clock it didn't seem to have any play on any corner of the car. One thing i did notice while under there poking around was that the front half shafts seemed to have some play where it meets the transmission, not sure if this is normal.. wanted to see what you guys thought.... thanks

tex... forgot to mention i have a carbon driveshaft, installed about 5000 miles ago and had the problem prior but it wasn't nearly as noticable, so i believe that takes out the possibility of a driveshaft bearing but could still be a yoke issue
