Our 2006 is showing its age and miles 228,000. It does this little shudder or shake accelerating around 30 mph. Not sure if it is transmission or suspension. Also not sure if it is worth putting $s into at this point. Front suspension very spongy. What to do. Every thing else good. Like those heated seats!

 

You might be starting to feel a worn cv joint - the right axle usually wears out first.
