[TR] rear leaf springs

[Mark Hooper]

I've never understood how leaf springs don't just build up a dust layer
between the leaves and then sand (abrade) themselves down to wafers in no
time. Always thought they must need a boot to avoid the problem, but having
seen many large dump trucks with huge leaf springs that spend their days in
dirt and dust, I guess it isn't so.

For a couple minutes yes.

To minimize the friction between the individual leaves. I like UHMW
(ultra-high molecular weight) Polyethylene plastic.

This plastic provides a low friction surface, similar to Teflon tape,
but with a much higher abrasion and puncture resistance. It was designed
specifically for commercial use on chutes, packaging lines, slides, and
anywhere high pressure metal to metal sliding contact occurs. It also
provides sound dampening, eliminating squeaks and rattles caused by
adjacent parts movement. The plastic's temperature range is -40 to +225
degrees F.

You disassemble the spring pack and stick the tape to the top side of
each individual leaf, except for the top leaf of course. This tape
virtually eliminates the friction between adjacent leaves in the leaf
pack and dramatically increases the spring's ability to react to bumps
in the road.
