Obviously I'm new here, but I have a quick question. I have an 04 coupe ex 4 cylinder, and i'm getting a slight shudder under second gear acceleration, mostly between 2500 and 3000 rpm. More apparent on turns, and most noticeable under moderate acceleration. both hard and very light acceleration seem to make it less noticeable. I'm going to check the grease in the CV axles, as well asmy wheel balance. Thanks for any input.

 

Looks like you are on the right path, if the "feeling" is coming from the driveline I would suspect the inner cv joint(s) are going bad.

 

I would agree with poorman on the CV joints, its seems like the most likely culprit. Especially since you said its more apparent during turns. Seem to be worse left vs right? If it is its usually the opposite side that is bad IE if its worse during left hand turns its probably the passenger side axle.
