Medium Pimpin' developed a problem last week. It started to shake between 45 and 60 mpH. My first reaction was to rotate and balance my tires. It still shakes.
I noticed that it is not as pronounced when you let off of the accelerator or floor it. I noticed that the shakes (and the growl) also dimishes when turning right (at higher speeds). I knew that my passenger front hub was failing. I thought that it may have been really worn and that it would stop when I replaced it. All'* quiet now, but It still shakes.
I have checked for warped rotors, loose suspension components, etc. to no avail.
Monday afternoon I will get it up on the lift and go over the suspension with a fine tooth comb, and give it an alignment. I don't have a lot of faith that I will diagnose the problem at that point.
Does anyone have any ideas for things to check?
