My 05 Fox DHX 5.0 on my Turner DHR has been feeling really wallowie.. Like theres no much life in it. I don't see any oil leaks but I bought the bike used two seasons ago and haven't had it rebuilt.

I usually run 75 psi to 125 psi.. no bottom out and a few clicks of propedal.

fyi I weigh 145ish with gear and run a 300 spring.
Would a rebuild make it feel more alive?

couldnt tell you if it would make it more "alive" but it would certainly help the shock live longer. I would rebuild it, to make it lively try the rebound.
 
If you have a 'squelching' sound under compression it's normally a sign of air in the oil, which if left unchecked means a lack of damping eventually. I rebuild my DHX every 3-6 months, just for safety's sake, and the oil normally comes out pretty dark.

Welshy. I have that exact sound. I'll get it in the shop this weekend.. I was going to wait for a push tune but a rebuild from a lbs should help tons then?

Yeah, definitely get it serviced then. Air getting into the oil normally occurs most often when the PSI in the boost chamber drops below spec, allowing air to work past the seals in a vacuum type scenario.

It's amazing when you service it the first time, it comes back feeling worlds better, and you wonder how you ever rode it before!

If you are relatively mechanically minded, consider giving it a go yourself, or if not that confident, but friendly with your LBS, ask to watch and help out, then give it a go yourself. I'd put it at a difficulty level parallel with Boxxers... Piss easy!

that's the plan next time...
It's the DHX with the external piggy though. not sure if that'll add to the difficulty

The same principles still apply, it will just use marginally more oil (to fill the connecting tube).

Aside from that, you just have the option to replace a few more O-rings. God i love replacing them. Nothing better than walking into a seal shop, buying enough O-rings to service your forks and shock a good 15+ times, and having the total cost come below $20.
