I was giving the car a full service and check over at the weekend. All but one of the shocks (both at front, one at rear) had a couple of mm's of red gunk down the sides of them. This seemed pretty much dried on now. I've only seen a shock that had recently gone and it looked more like a black oil. Handling seems fine, but I only know what it feels like when a rear shock goes.
If I remove the shocks in question, what should I look for? Little resistance to depressing it? Should it extract itself again, or is it standard for a used but working shock not to extract? Removing and replacing the shocks is quite simple. Actually having the experience to know a good shock from a bad one is a different matter.
The car has 82K on the clock and hasn't had the shocks replaced yet. Good or bad?
Any suggestions appreciated.
