I'm replacing the kingpins on my '39 Chevy Master 85 (solid beam axle - not knee joint). The shop manual specifies that if the clearance between the steering knuckle and the I-beam is greater than .006' then shim(s) should be installed. There were three shims in place when I took mine apart. When I installed new kinpin, bushings, and bearing the clearance was about .011' .

Here's my question: I added two shims, a really tight fit. Can a fit be too tight, or is it the case that if I got it together it's by definition not too tight? Sorry that I can't tell you the thickness of the shims - they came with the Kanter (TRW) kingpin kit.

All answers are appreciated. Thanks in advance,

Jeff Wilson

If the added shims brought the clearance within specification then it has to be right unless there are other worn parts that resulted in needing the additional shims. Of course there is always the possibilty the new parts were not really manufactured to original factory specs or the wrong part got into the box. Even the best of vendors can have the latter happen to them when someone is not paying attention.

If you can get as many shims in as possible - under the bearing, not on top, then you are about right. After the car settles in, you may find that there is more clearance than when you started.
