MACK MAN Posted February 7, 2011 Share Posted February 7, 2011 I have a 1989 Superliner,I have had the truck about 8 years.The truck is on neway airride,I use it everyday,pulling a flatbed run about 55,000 miles local a year,loaded one way come back empty.Anyway double frame,right at the end of the 5th wheel plate at the rear,the inside frame has a crack,it is on the top side of the rail.The crack is only on the drivers side,leave it alone?am I asking for problems?I took it to a frame shop in Tulsa and I have used these guys before and think they are real good and know there stuff,they told me leave it alone.as long as its double frame I will be ok,no need to get into alot of money and time.

David Posted February 7, 2011 Share Posted February 7, 2011 If you can get to the end of the crack and drill a small hole at that point, it may keep it from going any further.

HK Trucking Posted February 7, 2011 Share Posted February 7, 2011 Vee out the crack, weld it up, and grind it off smooth so it's not noticeable.A crack in the frame if discovered by a DOT inspector is instant O.O.S.

BAD DOG Posted February 14, 2011 Share Posted February 14, 2011 I would vee it out weld it an grind it off nice to hide it too. You don't want the DOT to find a crack.
