Other than the obvious fluid leaking or physical damage, what should I look for? they are OME Nitros. I pulled a shock and compressed it. Compression seems smooth and consistent. Return is slow but still comes back to full extension.
BTW, if you're in doubt and don't know the mileage of the shocks, then I'd probably replace them.
I know the mileage. I bought them new with the lift. Currently, 105K miles on them. Yeah I know, time to replace them. I think I'm going to try the RS5000X's.
I have the Rancho RS5000x shocks too and love them as well.I have those Ranchos and I love them.
