Old Chevy Truck Cab Alignment Project


I have started a little project on getting the cab on the old truck back to as close to factory alignment as possible. Well….how did it get out of alignment. Old rubber cab bushings that isolate road vibrations and jarring from bumps are installed at the corners of the cab and this is also the mounting point for the cab to the frame.

Other than having a cab that rides rougher, cab alignment can be affected. take a look at this:

See where I marked this pic…..cab is a little lower than the bed. Well…the hope is that since my bushings are old and have “sunk” over time that new ones will line this back up. This is important for me to know if its these bushings or suspension. See below:

Were I have this picture marked…..this side is a little less than an inch lower that the other side. So, I am hoping that news cab bushings will fix this. It may not….as it may be suspension adjustments, but you have to get the cab at least closer to factory alignment.

Here are my bottom part removed. As you can tell….not the best shape. But the two on the left are in better shape than the front. I am just glad they came out. I have a feeling that they have been replaced before at least the rear….(left two). These are the bottom bushings and not the part that is affecting the cab alignment. I will be taking those out after I get the new ones ordered. I have to use a floor jack to raise the cab just enough (couple inches) to get the old upper bushings out and new ones in. Here is a pic from a catalog that shows how it all goes together.

Below is what I hope mine will look like when I am done.

These are some pictures of what new replacement ones look like. I have removed mine at least the bottom part just to see if the old rusty bolts would come out.

Hopefully I will get to these in a couple weeks. I am ordering Monday.

Update

I have got this project done. I will be posting pictures on Monday hopefully. I have the alignment very close. Still have a couple of things to try and do….very minor. So pictures coming soon.
