Air line to connector popped out of the push in, 2004 FLH shock

Hi it could be the seal in the shock. These are air assisted shocks not just air. If the leak is not too bad leave it alone otherwise you may need to replace the whole shock. Regards Jim...

Raise the rear wheel off the ground and then with a no loss air pump apply more pressure to force any oil down the lines into the shocks, then release all air pressure and press the air line fitting collar in and disconnect the lines. THEN remove the upper shock mounting bolt and lockwasher and flat washer and then remove the lower shock mounting bolt and lockwasher and flat washer and remove the shock absorber assembly from the motorcycle. BUT do not lay it down as the oil will leak out and cannot be replaced so the shock would then be garbage. You could remove the air line fitting and plug the hole with a 1/8 NPT thread plug if the shock is to be retained and stored or etc.

Yes , the oil seal is available from Honda. If too much air pressure is put into the shock it is not uncommon for the seal to pop. A 5wt or 10wt shock oil should work just fine. Consider changing the oil in the other shock also.

Sounds like the shock you ordered was a dud! I would contact them and have them to send You a new one! Because they should not leak if they are new!

Either you have an air line leak or one of your shocks are leaking air. Soapy water can be used to check both problems. Put soapy water on the air line connections and if there are bubbles then that connection is leaking. If you don't find any air line leaks then put soapy water around the shaft goes into the body of the shock and again if you have air bubbles that shock is leaking. It is always best to replace shocks in pairs. In other word replace all of the shocks on an axel even if you just have to replace one. Please rate my answer for helpfulness.

you can get push on spring loaded couplings and other air hose parts at nappa auto store.

Could be just a leak at fitting or line, but try not to let it run too low on air while checking, that's not good for them. Spray bottle with mixture of a little dish soap & water may help you isolate it. Start at shock fitting and work your way back down the line(s)

you could replace the one shock but do you know why it is leaking oil? Typically unless there was something traumatic to happen to one of the rear shocks, then if one is going you can almost be the other one will go soon. I ended up having too many problems with the air ride suspensions. If you haven't yet, look into conversion kits as something to consider for down the road if nothing else. www.strutmasters.com has a great kit that is made in America and comes with a lifetime warranty. They have a good reputation and track record and can help you save some money and find the permanent solution if anything else goes wrong.
