Installing zerks for suspension bushings?

[pbs911]

I am going to replace the a-arm front and rear bushings and intall the sway-away control arms on my 78SC this next weekend. Well maybe over the next 2 weekends. Being that the polygraphite bushings resinate noise, I want to install zerks so I can periodically inject a little lube into those areas. I've heard of others on this board doing this. Does anyone have pictures, directions or other tips for this procedure? I understand I need the zerks and a tap, but what size and where are the best places to install them? Thanks.

I installed zirks on sway-a-ways on the bottom. I drilled a hole through the bushing to the zirk fitting so the grease can reach the inner portion. On the inner portion of the bushing, I cross hatched it to allow some grease to reside in it. The best this will do is grease the outer portion. There is no way to get the inner area without removing the entire plate. I have had mine in for most of the track season with no noise so far.

Thanks for the tip on the rears.

Any tips on installing zerks to lube the the a-arm bushings? Thanks.

Paul:
I know European Car Magazine has had a couple of articles on how & where to install these on the front A arms & rear swing arms. It's been during the last couple of years. I think I saved a couple of them, but I don't know where they are right now. If you have time, you might go to the library & check out when those articles were & which issues & copy them. Did you do a search on that subject on the board?

I did it.

When I installed modifed poly bushings on my '66 912, I drilled and tapped the front A-arm rear crossmember and the brackets that hold the front of tha A-arm to the pan. Looking at the arms from the front of the car, the zerks are at about the 8 o'clock position-as far away from the ground as possible, but just far enough from the mounting bolts so a socket can fit over them and just clear the zerks.

I used 3/8-24 thread zerks-available at any auto parts store-drill all the way through the crossmember or bracket, through the bushing to the inner hole so grease can get to where it's needed. Use zerks long enough to protrude slightly into the bushing itself so they won't rotate, but not so long that they interfere with the control arm.

Thanks. That's a great looking web site Clay. If anyone has not checked it out, I'd recommend it.
