I have a back shock (pro comp es9000) that is leaking oil. It is about 3 or 4 years old. I was wondering if i should just replace it, or if i should go with both back ones new? $40 each, not a big deal to replace both but if I dont need to i could always spend it somewhere else.

 

Bothe, You shockes are 4 years old so the shockes preformance did degrad. If you whant to save the mony then chang the bad one and see how it preform and take it from ther.

 

How many miles? 4 years is a short life span for shocks...

 

there is only about 17000 miles one the truck and the lift was on it when i bought it. i would think it would last more than that, but doubt it has any kind of warranty being that old. i dont notice any difference when i drive, the only thing is that the shock is covered in oil and there is drip marks underneath it. the shock is the only thing that is oily. i was just curious if i should go with one or both.
