hi..i just bought some fourth gen rims and after i put them on theres a little problem..sometimes when i brake, the car pulls to the left ..i got an alignment done a month ago without the new rims...today i brought my car to get the tires balanced ..the mechanic said tat they were off balance and i need two tires soon.. left rear and front right....could that be causing the problems and should i just rotate the bad tires to the back...one more question...i get this weird noise from the right side of my engine compartmnent..sounds like its from around the alternator..wat could it be ... its gone when i drive around for a little bit ....should i worry about it..i just had a new alternator put on a year and a half ago..so i dont think its the alternator..thanks for the help...
