The TT twin axle will make some creaks and moans under some TV turning conditions....., you may even notice that the tires appear to be flexing a little as well....... all normal. If you find that the axle noise is excessive after a few camping trips compared to other TT's in the campground, then have your RV dealer inspect the suspension. Also, make sure that the TT tires are at maximum PSI, and check the wheel lug-nut torque once in awhile during the camping season.

The Equal-i-zer brand WDH is a great hitch (with integrated sway control) and even when adjusted correctly may at times make some nosies. The dealer tech may not have told you, but the WDH should be re-adjusted once more when your TV/TT is under loaded conditions (ready to camp).
Once you have your WDH re-adjusted under loaded conditions, re-evaluate the level of noise it makes. The Equal-i-zer WDH installation instructions also identify's specific points for lubrication. Usually the heavier tongues weights can influence WDH noise issues.
