Bed alignment fix


Recommended Posts

Has anoyone got this fixed by their dealership lately? I hung a plumb bob off of both fenders and it was off almost an inch and a half side to side (measured to the center cap). Last time i mentioned it to the dealer they said theyed look than basically sent me home with "yea its off but i don't know how we would fix it so...." I plan on running a lift soon with new wheels and its going to look like crap if the poke is different on each side so i want to get this taken care of. Whats the move here?

my box was half an inch to the right, there is a plastic locator pin at the front left of the box, i had to remove the pin in order to get the box straight

No problems in having the bed installed without the pin? I would assume you have to remove more than 1 pin to get it to move no?

UPDATE: Looks like i got a better service guy this time around. They are handling the recalls now, and when i pick it up we are going to schedule something with the body shop to get the bed straightened. One question though, the bed bolts on from the bottom up correct? I just want to remove my bedrug myself if they will have to do it for the fix.

UPDATE: just got the truck back from the dealer and its better but not acceptable by my standards yet. Sadly i got to speak with the body shop guys and realized im dealing with morons so i took the truck back. They removed the pins so the hard part i think is done.

As it sits now the "poke" is still off by about 3/4" one side to the other. Basically the driver side rear tire sits about 3/4" deeper in the wheel well than the passenger side. ALSO the drivers side of the bed is inline with the cab while the passenger side of the bed aligns inside of the cab so that if i put a flat edge across the rear door it does not touch the bed.

So my theory, which i will test as soon as i can get a warm day or access to a heated garage, is that if i shift the entire bed to the right 3/8" it will even everything out.

 

Wish me luck

Thank you very much for this information, I will use a PLS to determine the condition of my bed when our little warming spell arrives later this week.

I have years of experience sitting up this equipment that production workers use to manufacture a vehicle and cab and deck marriage to the frame unfortunately seems to be a nightmare and now I am scratching my head that a bed off 1.5" passed QC and made it out the door to the jockey lot or rail yard as some manufacturers use to transport new built vehicles.

The plastic alignment pins which I have seen referred too are not the alignment pins which the cab and deck are “married” installed to the frame, they are just used for keep in place of the cab and deck before the bolts are impacted “shot in”. The body frame holes should never been that large to allow movement of the cab and deck to the frame at most you should only get 3/8” or 10mm movement, anything more than that, the vehicle should have been flagged for QC inspection and they would take it to a specific area, disassemble the vehicle determining where the mistake is and correct it either with the frame manufacturer or bodyweld shop.

While you are aligning your bed could you get a dimension on the frame hole and the diameter of the plastic pin?

Production workers use long alignment metal pins that goes through the bottom of the frame “cab and deck mounts” then with a pendent they manually sit cab and deck to the frame, remove alignment pins and shoot the bolts which is registered on a torque management device or pokoyoke as it is known in the industry.

With your bed being off this much, there could be multiple or a single cause for this, but it definitely needs to be determined, isolated, and fixed.

1. Frame is not to spec

2. Bed was welded way off in the bodyweld shop which GM now has robot jig tables that are severely out of alignment.

3. Production workers leaning on your body as they are performing other processes, “which would mean cab and deck to frame marriage was not a completed process and GM has a huge failure there” thus causing alignment issues.

I can't measure the pins since they took them out. Im probably going to leave it till the spring. Don't feel like crawling under the truck in anything less than 60deg weather lol. But my hope is i can get that 3/8" movement in the correct direction.

 

side note: anyone know the torque spec for the bed mounting bolts?

54 FT. LB I believe is the torque spec for that bolt.

Mine is off by 1" and you can measure it between the rear tire clearance. I first noticed in my driver side mirror. I thought it was an illusion. When I was washing the truck my hand and sponge would not fit between the wheel and mud flap on the driver side. Did not take it in since it is always a pain to get a loaner or have somebody driving you to and from work.

Anybody else feel like the offset bed alignment could be the culprit of the shake/vibration issues with these trucks?

 

Checked and mine is pretty close... +,- 1/4 inch. Truck vibrates regardless :o/
