Cab alignment issues
Hey All,
I am currently trying to get the cab and box to align on my 79 F-250 CrewCab. It was t-boned before I bought it and the cab was pushed out of alignment from the box by about 1 1/2" or so. I loosened up the rear cab mounts hoping I could simply pull/push the cab back into alignment without having to take the whole thing down but that hasn't worked very well. I got the alignment to within half and inch or so now but it still doesn't look quite right because of it. Any tips on how to get it realigned better? Or am I going to have to pull the entire front end and cab off the frame to get it? the frame as far as I can tell isn't bent at all so that is a plus.
Thanks

Before going any further, verify your cross-measurements in an "X" at identical points on the left and right frame rails to determine if the frame is bent.
It's as easy as using light fishing line and some washers.

Here's a question, where did you happen to check if the frame was bent? Most often times guys use too short of a cross measurement and or in the wrong areas and think the frame is straight when in reality it's not. The best thing to do would be to measure from the center of the front rad support mount holes to the front spring perch for the rear leaf springs. That way you will know for sure if the frame has any misalignment at all. Also be sure to keep the measure tape or string as straight as possible. Make sure not to allow the measuring tape to sag or bend around any obstacles on the frame as that will throw off your measurements. I say this because I wanted to make you didn't just pick two points to measure from that were just under the cab. An inch and a half difference in gaps is a huge difference. I find it hard to believe that you could have that big of a difference and the frame still be perfectly straight. Tolerance from the factory even on these old trucks is less then a quarter inch. Any more than that and you will have tracking and tire wear issues at the very least. I highly suggest that you go back and remeasure or take the truck to a frame shop to have it measured.
