Can Donahoe Front Coil-Overs Leak Fluid?

A long time ago I installed Donahoe front coil-overs. Is there liquid in there that can leak? I am trying to figure out if the coil-over is leaking or the half-axle CV boot. If it is coil-over, are those Donahoes rebuild-able? I noticed they are no longer in business. If they cannot be re-built, who makes the best coil-over these days?

 

Donahoe turned into Icon vehicle dynamics and yes they can still be rebuilt and should be if they haven't even been before. They would be at a minimum 8 years old by now since donahoe changed their name. They can leak as well, and after at least 8 years it wouldn't surprise me if they are leaking. They should be rebuilt every 30-40k miles

 

Wow, I installed them like 14 years ago and they have 180K miles on them.

 

Yup then I'd say it's time, they probably haven't been performing their job very well for a solid 9-10 years haha
