Some strut bushing info
Nice edit, but your childish response is still quoted here.
Clearly you can't have a logical discussion on the topic. If you understood how the suspension actually works, you could.
And, I have plenty of friends. Just none that work for Napa with access to storehouse inventories. I have what I need anyway, my cars all have adjustable strut rods. If the ones I ordered ever come in I have a little side project for them, but I'm not holding my breath and it really isn't important.
72 Have you used PST Polygraphite LCA bushings? Apparently they self lubricate to some degree.
Thinking of putting a set in my 67 Barracuda
I have not. I have used the Energy Suspension poly LCA bushings with great success, and have recently started using BAC's Delrin LCA bushings. The Delrin is also supposed to be self lubricating. I have found that the Firm Feel greaseable LCA pivots fit both of those bushings very well, so, I'm not particularly concerned about the self lubricating bit. The FFI pivots are far better made than the stock pivots were, so no, I'm not worried about the grease hole reducing the integrity of the pivot either.
I have had some experience with heims used in suspension systems.
IMHO
Yes - if set up correctly they are easy to adjust, in particular say for changing conditions at the track.
Yes - they do allow for freedom of movement when tuned correctly.
Yes - they look cool.
No - they do not last long, even the really tough expensive ones.
No - they are not quiet, they do tend to rattle in some applications.
Unless you are into some serious driving like autocross I cant recommend them for your average street machine.
Actually, I've found that the life of the heims depends a lot on the location. The heims on the adjustable strut rods on my Challenger have gone over 70k year-round street miles and they're still tight and quiet.
But at the UCA's on the same car I've only been getting about 7-10k out of the heims, obviously it's the same car so they're seeing the same road and weather conditions.
So for me, I have absolutely no issues recommending adjustable strut rods with heims for the street. They'll outlast everything else in the suspension. By the same token, I don't recommend heims on the UCA's for street use, poly or delrin bushings at the UCA on the street for me.
What pins do you have the Delrin bushings on?
I have my Delrin bushings on Firm Feel greaseable pivot pins. They had the best fit of all the ones I tried, but BAC has since started selling their own. I'm sure that theirs fit well too but they weren't available when I bought my Delrin bushings.
