My car have a very rough feeling and bouncy ride even in a smooth road. I suspected wheel alignment and balance, but even I did wheel alignment it get wrong after a months. I have no idea which suspension part causes this and which one I need to replace. Can you help me?

Good morning,

The first thing I would check is the tires. Make sure the tires are not worn where there are high spots that will cause the car to ride unevenly.

Did anyone check the tires when it was aligned?

The other thing is the shocks. If they are worn out, it will not stabilize the ride and allow the car to constantly bounce giving you an uneven ride. You should bounce the car by hand and it should only bounce 1 complete time and return to being stable. if it keeps on bouncing, the shocks are worn out.

Compress and extend the shock absorber rod, and check that there is no abnormal resistance or unusual sound during operation.

If there is any abnormality, replace the shock absorber with a new one.
