4900 W/S cab frame bracket

First off, Howdy! Nice to see a good truck forum, great base just need more members! Anyway got a 4900 with integral bunk, drivers side rear cab frame bracket ripped right off the frame around the bolts, drivers side has the torque rod attached to it, the bracket is pretty lightly built. Had to weld the pieces back together as the new one is a few days away just shy of $600 Wondering if it's the extra weight of the bunk but the cab is pushing over to the drivers side, fair amount of pressure pushing on the torque rod.

Any pictures? Might tell a story. I thought Paccar parts were expensive?

Never had this problem with mine. It is a 99 with 1.1 mil on it. One thing that is an issue and you may want to check is the cross members on the frame seem to loosen up quite regular. These cross members are between the trans and the end of the sleeper. OEM members are aluminum. I had some steel ones made as I was told they would not get loose again. I was lied to as they are loose again. This summer I will get under and put larger bolts in with jam nuts. We will see how this works.
I ramble on as the loose cross members may be the cause of your broken bracket. - Too much frame flex when driving off road or even entering parking lots at an angle.

I forgot to mention the truck is an 07 model year. I checked the crossmembers and all is tight, one year later and I see that the new bracket has started to crack again around the bottom bolt... I'll take some pics next weekend when I do some repairs.
Thanks!
