I've been noticing a nasty rattle or hop in my front right side tire when I pass 3000RPM in every gear.
I have already re-balanced that tire, had the tie rods changed, and the alignment was done about a month ago.
Now just alil 411 on the Coupe, it has the full Front ES Bushings so I know its not that, and the left hand side Ball Joint was just replace. Axles have also been replace recently.
Now bascally when I get on the freeway and punch it a little over 3500RPM the Right-side tire starts vibrating alot, I was possibly thinking it can be the ball joint, but can it also be the A-Arm?

TIA...Juice

 

Check your engine mounts. Have you checked your axles at all?

 

I have the same problem -- I think... Mine only vibrates when there is power going through the axles ( if i'm coasting it's fine) so I figured it was the CV joints... I know they are going bad anyways because they pop every now and then, but maybe it is something else. hopefully you'll figure it out so i don't have to :-)

 

Engine Mounts are perfect, Axels are almost brand new and CV joints aren't torn.
Could the Half-shaft be the problem, because I grabbed one of the CV Joints on the left hand side of the car and where it connects to the half shaft it seems to be a little loose.
But just like e_r_i_c , mines doesn't seem to have that problem when i'm coasting.
I guess i'll just go ahead and change the half shaft and see if that fixes the problem.
