Is this a common problem with our trucks?

I've torn down 2 trucks lately and both had the same crack on the front crossmember. Also check out the cracked trailing arm mount on the rearend housing.

I'd bet that's from frame "flex", as in the type of flex that offroaders talk about.

Re: Check your front crossmembers for cracks!

Since the only 2 trucks I've torn down have this problem I would say there are a lot of cracked crossmembers out there...check yours out...this could lead to other problems.

I agree. Drill a hole at the end of the crack (to stop it from growing) then take a grinder "V" the crack out and weld it back together. It will be good for another 40 years or so. WES

Re: Is this a common problem with our trucks?

these for the most part were not pleasure vehicles they were used and abused work vehicles in extreme service situations most times
