First off , the car suddenly started having serious vibrations from the front right side wheel at about 70-80 MPH on the highway. Then i noticed at low speeds a squealing sound coming from the front right wheel. Any ideas what this could be ?

you are taking righthand turns too fast

say what ?

lay off the four leaf clovers a little bit...huh?

Check your belts. They might be worn down and slipping or the tensioner might need to be tightened a bit. I don't have an answer to why your car was vibrating from the right, front end.

oh snap,,,,

had the belts replace a couple of weeks ago. noise just started about 3 days ago. doesnt happen when i am stopped, only when rolling and the wheels are moving. you think is still might be related to the belts ?

bad rotor?

The tension on the belt might not be adjusted correctly. Check out this link. It's a part of the "how-to" for replacing the alternator.

Check your axle?

VIBRATION PROBLEM SOLVED!

it was as simple as balancing the wheels. Squealing problem however is still intermittenly there.

Any update on the status of your rotor? Take it to a local Midas or something and they'll give you a free inspection, measure your rotors, etc. I took mine recently and found out it was below the discard thickness.
I think I'm having the same problem as you are with the squealing from the front right side. I'm going to replace my front rotors and see if there is any difference. Needless to say I'm going to try to replace my pads and rotors myself tomorrow (Midas quoted me $400 for parts & labor for pads on all 4 wheels and new rotors for the front axle) I went to Autozone and got both sets of pads, the front rotors (nothing fancy), brake cleaner, and some packet of grease all for about $85.
