CAUTION
CHECKING FOR LEAKS
1. Inflate the air spring to 30 PSI and spray all connections and the inflation valves with
a solution of 1/5 liquid dish soap and 4/5 water to check for leaks . Spot leaks easily by
looking for bubbles in the soapy water .
2. After the test, deflate the springs to the minimum pressure required to restore the normal
ride height, no less than 5 PSI .
3 . Check the air pressure again after 24 hours . A 2-4 PSI loss after initial installation is
normal . Retest for leaks if the loss is more than 5 lbs .
FIXING LEAKS
1. If there is a problem with the swivel fitting:
a. Check the air line connection by deflating the spring and removing the line by pulling
the collar against the fitting and pulling firmly on the air line. Trim 1” off the end of
the air line. Be sure the cut is clean and square (see fig. 31). Reinsert the air line
into the push-to-connect fitting.
b. Check the threaded connection by tightening the swivel fitting another 1/2 turn. If
it still leaks, deflate the air spring, remove the fitting, and re-coat the threads with
thread sealant . Reinstall by hand tightening as much as possible, then use a wrench
for an additional two turns .
2. If there is a problem with the inflation valve, then:
a . Check the valve core by tightening it with a valve core tool .
b. Check the air line connection by removing the air line from the barbed type fitting.
DO NOT CUT THE AIR LINE COMPLETELY OFF AS THIS WILL NICK THE BARB AND
RENDER THE FITTING USELESS .
3 . If the preceding steps have not resolved the problem, call Air Lift customer service at
(800) 248-0892 for assistance .
