Whirlpool washer spin cycle towels only problem

I have a whirlpool WTW4955HW washer that’s when washing towels, it’ll go unbalanced during the spin cycle. Things I have done… 1. Distributed the towels evenly in drum 2. Did less towels did not overload 3. Leveled washer 4. Replaced all 4 suspension springs/rods old ones seemed fine but replaced anyway Washer is less two yrs old. Had no other problems with it. It only does this with towels. Any info would be appreciated. Thanks
