pulling dent out of engine crossmember

[zakt]

I have 1967 F350 2wd and the engine crossmember has a dent in it I want to pull out. Im thinking a slide hammer with a stud gun but not sure what size slid hammer 12lb?? Yea, I know it will take awhile to get it out but its boxed in underneath and can only be accessed from the top. Thoughts?

I think you'll need to use the attachment where you're pulling on 4-5 studs if it'll work at all. I have the stinger and would never believe it could pull out a crossmember. A portable hydro pusher(?) will be more suitable I guess.

are you sure that the frame and cross member are square? if you doubt it is, have someone from a frame shop look it over for you. i really doubt that a stud gun and a slap-hammer will be able to pull a dent out of the cross member, a porta-power definately will work the best in my opinion

It may be prudent to call a few junk yard to see if you can get one cheap.

I have attempted what you are describing and it doesn't work. At least I coudn't get it to work A crossmember is to thick. I even heated it until it was red hot but then the studs just stretched and broke. The heat conducted from the cross member to the studs. I have the bracket that ties a bunch of studs together and that didn't help either. What I did was cut out the dent and replaced that section with new metal.

I dont know exactly what your dealing with looks like but you may be better off cutting the section out beyond the damage,work it flat on the bench with some heat and weld it back in.
