Question DIY Straightening Frame, any ideas?

My '82 hit a guy that U-turned three years ago. Been driving it since but tires wear screwy and pulls to right a bit. The right front seems pushed in/over about 3/4-1 inch, hood miss aligns. Have you tried using those porta power rigs or what ever? I just wonder how resistent the frame is to pull or push back... I'm not sure if its bent at all nehind the cab but my drivers door is slightly off as it doesnt close as nice as before. Truck was hit in same place by po.

Is a come-along powerfull enough to pull the front back. Could chain it to a RR track Dont want any safety advice thank you........ Thanks, Bill

For all the grief and trouble just take it and have it done.

i can do this at home and have the anchor points in the floor but time wise it is cheaper to have it done.

The pulling is not that hard but knowing how far to pull and being able to measure as it is being done is so very nice .

The time spent measuring alone costs me well over a hour in labor that is not billable .

I can`t say about a Come Along ( How many Tons??) as I have always used Hydraulics to pull or push things most often at the lowest 20 tons usually 50 tons .

Good luck

I would think someone would have an idea of how resistant the frame is to pulling to one side about an inch, not talking about stretching which I know usually only a shop can do if possible. Not looking for perfection just to track better. I'd rather find a same year truck with bad drive train and switch but that will have to wait for $$$ and time. Theres no sign of a warp or kink in the box frame but the hump might be compressed a bit behind the right wheel?

The accident was a hard hit and bent the front axle housing, found a good one and had the front end rebuilt. I drove it home after putting the spare on but was weird driving. Then I had a frame shop pull the frame but did a crap job, more of a temporary fix to get around.

I am guessing more to this story then your telling so be it.

If you all ready had it pulled and your not happy with the job why did you not address that then.

if people do poor work and continue to get away with it it keeps on happening .

If it was hit hard there is only so much one can do.

Does this have the stock suspension??

Are you able to get the alignment within specs??

If the cab is twisted getting the frame straight will not help.

If the truck tracks straight but looks off kilter because the cab is twisted on the mounts you have a whole other problem

Pictures would be a big help!!!

I was surprised at how strong a core support was. I worked in a body shop one time and the owner had me to chain the rear axle to some anchors and it still drug the car until the chains tighten. I can only imagine how strong both of the frame horns and the cross links adding to more strength.

We did have a guy that would come and straighten frames and he had a pneumatic/hydraulic set up and it was powerful. I don't think a come along would work. I would suggest several or a chain driven assembly like a hoist of some sort for that kind of power.

If the frame isn't kinked, I would try another shop somewhere. I have had frames fixed for around $250 for what sounds like the type of damage you are explaining. Just need to shop around.

I'm not explaing right or your not reading right? I had to have a shop pull frame and axle a bit just to be drivable and price was ok,dont remember what i paid and wasn't going to spend more with those guys, they had a real attitude. At least i could travel to get the newer axle housing. I went to another frame shop later that gave me a quote of $670 i think. He wasn't sure the right side could be streached all the way?
-stock suspension....
-Cab is ok just the slight door alignment on drivers side, sometimes have to close it twice to latch.
-Wont spend to align till frame is straighter.
-I think it tracks a bit off but not so most people would notice.
Do u really want pics.lol

Avatar pic is after i did repairs to pass the BAR Test to get it registered as i bought it back from insurance co.
Maybe all i can do is chain it to the caboose of a train?

Honestly, if you want to do it yourself and do it properly you would have to measure how bent it is and where. Then pull in the right direction. If you have it aligned, you can see how far off every thing is and have real data that can help you too, having an alignement checked is often cheap.

It can't really be aligned with the right frame rail pushed back as far as it is. The toe adjustment is correct. Your right of course to measure everything to know what needs to go where...If it turns out I can actually get it better then might not cost much to make a streach pull on the right rail at a shop. Thing is i know a pull or push from one spot can move things off in another making it tricky.

Not sure how but have read of guys in the wild bending there frames and straightening them in wild also. maybe they weren't that bad?

Take it to a shop with a quality frame machine, preferably a Car-O-Liner system....end of story. I can't even begin to think about a frame pull without a quality machine to measure the points. You can't simply "eye ball" a frame pull.

If i could afford a frame shop I would have had it done and never have asked here. Eye balling it could be 60% improvement till i can do things right.
