thumping sound

maybe the plastic liner is coming loose on the inside front portion of the wheel-well?

Sounds that either come or go when turning the wheel in one direction or another generally point to a wheel bearing, or in far less cases, to a CV joint. It's kind of hard to say though since the term "thumping" is really not very descriptive.

I don't get a real feeling from reading your post that you do a great deal of car repairs. Am I reading that wrong? If that's true, there probably isn't a lot you'll want to get into on your own in the front end of your car.

so you?re thinkin? cv joint or bearing?

Jack up the right front wheel off the ground and let the wheel spin free -- slowly. A bad wheel bearing will make a pronounced vibration at one point of the rotation. Check the CV joints while you're there for holes in the boots and grease leakage.

PS: Wheel bearing and/or driveaxle replacement you /could/ do yourself...but much better to let a competent garage do it for you.
