[TR] TR4A upper wishbone bushing choices

[Greg]

Thanks Chris and John.

I've added ball joints to the task and will lube liberally.

    It depends on what you want from the suspension. The original rubber 
    bushings provide some compliance (softness) in the ride; 
    nylatron/Delrin/poly will not, so the ride will be stiffer (and perhaps 
    make the handling a little more precise).

    I did an experiment, long ago, with Delrin on one side and poly on the 
    other, on my autox GT6+, and didn't really notice a significant 
    difference in performance.

    The two part poly bushings are easy to install and last pretty much 
    forever (unlike the original rubber ones) and that's what I use on any 
    Britcar suspension that I rebuild. I haven't bought any for a while, but 
    used to get them from British Parts Northwest.

    Lube them up with a long lasting synthetic grease (Aqua Lube is a 
    popular choice, designed for trailer wheel bearings that will be 
    regularly submerged, but pretty much any silicone grease will do fine) 
    or they will drive you crazy with squeaking.

    If you've got the upper wishbone apart, you might as well put in a new 
    ball joint, too.
