My Explorer was diagnosed with a "leaky" right front shop while wintering in AZ. Returned to my home in Utah and went to the dealer. I asked him to check the "suspension". He said all looked o.k. I then told him of the AZ diagnosis. He put the car on the lift again and said the technician said there migh be a minor leak on the left front shock. I have not made any repairs as yet.
Is it necessary to change springs when changing shocks? on 2002 Ford Explorer
Unless you feel the ride quality is not what is should be, I would not worry to much about changing a slightly leaking shock. It is not commonly necessary to replace the springs when the shocks are replaced unless the spring is actually part of the shop.
