Is there a seal that goes between the strut and the control arm on each side to seal that area of the spindle pin? It looks like Jalex has the remnants of a seal showing but I didn't see anything on the carpartsmanual diagram

Somebody just asked about this, calling them "rubbers".  I thought he meant bushings but apparently he meant the seals.  Might be that Jalex doesn't really need the bushings.

Actually, Patcon, you were there in that thread.  I've not seen those inner "rubbers" but who knows.

There is no stock rubber or seal between the control arm and strut. It appears that someone did try to put something in there on this car.

I remember that now.

I think Jim is understanding what I was referring to. You can see what looks like 3/4 of a seal coming out between the control arm face and the strut tube.

Please look at the picture closely. The bushings i need are the ones that look bitten. Looks like a part of it fell down.

He did.  We did.  We know what you're talking about.  Those aren't supposed to be there.  They are not bushings.  They are rubber seals, to keep dirt and moisture out.  Somebody added them to your car, they are not normal.

I would say no. Leave it alone and enjoy driving your tuned Z!

This is the kit i bought 3 years ago and had a shop install each and every bushing. I am still wondering the name of the bushings installed ib those rear control arms.

Then they stiffed you on those bushings...  The Energy master kit comes with bushings and metal sleeves to replace both sides of the rear lower control arm bushings (inner and outer (inboard and outboard)).  I was going to make a comment on your pictures of the LCA, rear hub, and pristine (if dirty) lock pin nut.  It's obvious that no one has pulled your spindle pin.  And it's very obvious that a new set of poly bushings has NOT been installed on the outboard side.

(In the picture above, the bushings for the rear outboard LCA are just above the steering rack bushings (8 black "tophats" and 4 metal tubes) - just above them is half of the inboard bushings for the rear LCA (4 large "tophats" and 2 large tubes))

edit: Looking at the pics again, those might be poly bushings, and the shop might have had a bad time getting getting that hub and LCA back together again...  (Is it really that dirty in Panama??  Only 3 years?)  With the Energy poly bushings, there should be bushing showing between the LCA and the hub -  it's a VERY tight fit and difficult to get together without damaging the bushing.  They may have cut that one putting it back together...  Those bushings can be a real challenge if you haven't done it a time or two.

Please let me know which kit must i order for both arms. I guess that shop did not had the required experience and i am taking it to another shop where i can supervise what they are doing.

Don't mind that the listing is for the 280Z.  If you search the site for the 240Z rear lower control arm bushings, you'll see that they are the same part number.  The rear lower control arm is the same in all S30's.

Perhaps I have an insite. Fact. He had a set of poly bushings installed. If you have done this job, you will remember that the inner and outer half of each of the pairs of outer rear control arm bushings have a thin lip on them.

Here is a picture of rear control bushings from energy suspension. The outer set is in the center of the picture.

IMG_3459.JPGWhen installed that thin lip would visible/present in that gap, unlike stock where the inner bushing is completely different and has no lips. That's what is damaged in his picture, part of the lip is gone. Does it matter? No. If the pin bolt is properly torqued, the inner metal tube in the control arm is locked to the face of the strut where the pin goes through. Since the control rotates with respect to the strut at this point, that lip can get damaged. Does not matter.

As long as that horrible sticky grease the bushings come with is generously used on the spindle pin, it will last for ever.

I think that you're probably right.  If he had told the whole story from the beginning it might have been more clear.

Polyurethane is over-applied for the Z's I think.  The sellers are just replacing rubber willy-nilly, no deep thought about appropriate usage.  More parts equals more money.  It probably is falling apart because it has dried out and the lip is too think for the gap.  I'd replace them with stock Nissan rubber.

I wish I'd used rubber instead of the polyurethane in hindsight but the Energy Suspension kit was complete and readily available plus much cheaper.  The poly is okay just to harsh for me.  

I've learned a lot since I started reading/researching instead of asking what whomever happens to be replying to my post recommends.

Even better...

Okay. So you recommend stock nissan bushings instead of Energy suspension brand?

For that area, yes, I'd use Nissan's bushings if you can find them.

i only see this kit available:

https://www.amazon.com/Energy-Suspension-7-3104G-Control-Bushing/dp/B000CGUJOE/ref=sr_1_1?s=automotive&ie=UTF8&qid=1533832428&sr=1-1&keywords=Energy+Suspension+7.3104G

I dont think i need all of these bushings as i only need to replace the ones that were wrongly installed.

The ones i need are the ones pointed in the following site:

https://www.totalzparts.com/product/datsun-240z-260z-280z-rear-suspension-inner-control-arm-bushings-1970-78-nos/

Quite expensive indeed. Please confirm.
