Hello.
I have a gurgling sound in my bath tub whenever the lift station is run in the basement. Basement has bathroom rough in, but nothing else, other then laundry. Tub gurgles when lift station expels water form washing machine. This sound is not present when flushing or using upstairs fixtures. Does this sound like a venting issue. Any ideas? Thanks??

Does this sound like a venting issue.
Sure does! Gurgles are produced when a vent's blocked forcing the discharge to vent through a fixture trap. In this case your bathtub trap. I would snake two roof vents. The washer vent and the lavatory vent in the bathroom. Put out enough cable to reach the base and 20 feet more. Good luck, Tom
