I'm hoping I can get some feedback regarding the rear leaf spring U-
Bolt top-plate on a 1991 Chevy K1500 pickup.
I have attached two gif drawings for reference. Here is the download
link for the drawings, only 201.19 KB...
Referring to the drawings, my questions are regarding part # 5
(spacer) of drawing A, or what is called the "top plate" in drawing B.
I purchased the top-plate from the GM dealer and I know it's the right
part because I used the Vin # to order it and I verified the part
number at two different dealers.
When I installed the top-plate, the nut on top of the leaf spring
center-bolt would not go all the way through the hole in the top-
plate. If anything, the hole in the new top-plate looked a little
bigger than the hole in the old top-plate. I went ahead and torqued
the U-bolts to factory specs of 81 foot-pounds and followed the
correct tightening sequence, thinking this would force the nut through
the hole in the U Bolt top-plate (it seemed close enough).
The ends of the top-plate are now clamped tight against the top of the
leaf springs. However, the center of the top-plate is not touching the
top of the leaf springs. The nut on top of the leaf spring center-bolt
was not pushed all the way through the hole in the top-plate. I can
only guess that its' designed this way for some reason but I wanted to
check to make sure. I replaced the drivers side today and I'm
replacing the passenger side tomorrow. I cannot just look at the old
one that is still on the passenger side because there is so much rust
present, I cannot tell if there used to be a space there or not.
According to the factory service manuals I have, there does not appear
to be any other spacer or anything that would "take up" the space.
I did not install the plate upside down, it's installed just as shown
in drawing A and that's how the plate was originally installed as
I would really appreciate any feedback anyone might have on this.
