Push down on each corner of the car..

Both front sides when pushed - make a 'gasp' of air noise..

The back ones dont.


Time to get these changed? Monroes good enough?

first thing
Do the back ones come up to the original starting postion becuase if they don't or are really slow then yes it is time for a change

Monroes are good. One thing is for sure, buy decent shocks and it's well worth it
