troubleshooting suspension system

pump activates but no action

You probably need to put a new hydraulic line on your rear suspension system and properly fill it with oil. Traxxion probably sells the best hydraulic line as it has a braided cover.

Does the display indicate that it is changing? If so, you may just have to add fluid to the system. As far as the braided line, you can change it but just refilling the system will may solve the problem. The original hose may have stretched slightly, but probably won't happen again. Did this to my 2004 and never had ti happen again.
You should be able to hear the pump start to labor between one and two on the display. Mine didn't start until 12 and refilling did the job.

Don't expect the back end to jump up even when it's working properly.It really doesn't move very far at all compared to the Wings with air shocks.
