I recieved 2 parts springs for pusher axle that i ordered. After my mechanic evaluated pusher axle we decided it was in to bad of condition to repair so i took axle off and decided to put strerable axle on. I contacted Kenworth Northeast of Buffalo that i needed to return springs they picked up parts and took back, 2 days later they were back on my porch with slip saying no returns if i new i couldnt return i would never have ordered as the cost is 450.00 per spring.uve contacted them several times and they avoid me and will not accept return. I cant afford to 900.00 for parts i cant use . I dont know what to do your help would greatly appreciated.
