suspension knock...I found the source......
I found the source of my nokcing in the suspension. Its the new plastic bushings I installed...they squeak making a sound like a nock...and its only on the passenger side.
Any ideas how to quiet them down? |

You could try it in stages. First, pray in some spray lubricants or silicon spray to see if that takes care of it. If it does, it will probably be temporary. Second, you could try an liquid product with molybdenum disulfide suspended in it. It's sort like of a penetrating fluid with moly in it. Spray it or drip it in. Lubecon makes some in the U.S. It would penetrate & (hopefully) leave a dry, lubricating film of moly disulfide. That might last a little longer. Last you might try drilling, tapping & installing a grease zerk (zert ?), so you can force grease into it.

I just finished adapting and installing polyurethane bushings for the front control arms on my '66 912, and went ahead and fitted them with drilled and tapped zerk fittings so I'll be able to lube them when (not if) they start to squeak. I used liberal amounts of the special poly grease when I installed them, but it only lasts so long-I did the same thing when I installed a full set of poly bushings on my daily driver/autocrosser 5.0 Mustang a few years ago, and it sure was easy to crawl under the car and hit the zerks with a little grease to quiet the bushings down. On the 912, I simply drilled through the crossmember and the front brackets, all the way through the bushing to the interior, then tapped the hole just deep enough for the zerk (3/8x24, if I remember correctly), but leaving the hole open all the way to the control arm to allow the grease to flow around it, between it and the bushing. One handy side effect of doing it this way is that the zerk fittings act to keep the hard poly bushings from spinning inside the crossmember.
