TWIN TUBE PIVOT SLEEVES |
| DJM Suspension has solved a small problem with squeaky or rough
pivoting urethane bushing. This condition is mostly caused by over tightening
the pivot bolt to the bushing. When using urethane bushings, the steel pivot
sleeve must be able to move freely around the pivot bolt. Over tightening will
clamp either the sleeve or the bushing into the mounting flange restricting the
pivot movement. Using the new DJM Suspension twin pivot sleeves solves this
nagging problem. |
DRILL 1/8" HOLE |
This new
twin tube pivot design enables the inner sleeve to be clamped in the mounting
flange (fully tightening the pivot bolts) because the bolt is no longer used as
the pivot point. The inner sleeve also holds the flange width eliminating the
over tightening problem that crushes the urethane bushing. |

FILE BURRS |
The outer
sleeve is already installed in the control arms but still needs a small hole
for a grease path. Using a 1/8” drill, line drill though the zerk fitting
hole. The drilling operation will leave a burr on the inside of the sleeve that
must be removed. Use your rat tail file to completely remove all burrs from
drilling and on the ends of the sleeve. Make sure you clean all chips and
dirt. |
 |
INNER SLEEVES ARE .050" LONGER THAN THE OUTER
SLEEVE. |
Now that the outer sleeves are drilled and cleaned it
is important to check the inner sleeves. These sleeves should be about
.050” longer than the outer sleeve. You should assemble them before
greasing to check that the length is slightly longer and they rotate smoothly.
Now it is good to lightly grease the inner sleeve and insert it into the
control arm. Install the control arm per the installation instructions. The
pivot of the arm should be smooth. Tighten pivot bolts to 40ft lbs DO NOT OVER
TIGHTEN use a drop of thread lock on the nuts. |
