Hello Teriann and others,
The tape idea seams like a good plan, but I think you might be creating a
possible squish problem with a relatively soft material between the leafs. I
would think that the tape can collapse a bit under the axle and between the
U-bolts. This might be evident if the U-bolts can be further tightened later
on. I've read that even a thick coat of paint between the leafs can cause
problems and should be avoided. Google leaf spring rebuilding. I disassemble
the springs on my TR3, cleaned them, repainted the leafs separately with a
light coat of paint then scuffed them with a Scotch Brite pad where they
contact each other, applied a little bit of high pressure grease between the
leafs and reassemble them. I also dressed the sharp edge at the end of each
leaf with a sanding disc to limit the gouging that occurs. That's my 2 cents. I
think they are working beautifully. I also installed the ARE axle locating kit,
this is a great product.

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.
