FRAME AND BODY ALIGNMENT - All Hudson Models 1948 through 1954

FRAME ALIGNMENT
The frames of all Hudson models 1948 thru 1954 are similar in design although there are differences in dimensions due to wheelbases and changes in other details.

To check the frame for any misalignment, determine the model and refer to the correct frame dimension illustration [in 1948-1954 Hudson Body Service Manual]. The various dimensions shown may be used as a guide in checking alignment and covers only the more important diagonal measurements that should be checked; however, many more diagonal measurements may be made in the same manner.

Diagonal measurements should be taken when straightening the frame, and the measurements from similar points on the right and left side should be equal. These measurements make an excellent cehck for any out-of-square condition and misalignment and will quickly determine which section of the frame is bent and where pressure should be applied to restore correct alignment.

One method of checking is by use of tram gauges. When using tram gauges, keep the cross bar level to insure accuracy when making all measurements.

Another method is by using a "plumb bob". To insure accuracy, the car should be on a level floor and the points measured should be transferred accurately from the frame to the floor, then the distances between chalk marks on the floor may be easily measured.

After the frame has been straightened, the side rails and members should be closely inspected. If cracks appear these members should be reinforced or replaced.

If it is necessary to weld-in a new frame section, localize the heat in order to retain the original steel hardness. All welding should be done with arc welding equipment.
